    Opinion by Judge Bybee
    SUMMARY**
    Wiretap Act
    The panel granted in part a petition for rehearing, filed an
    amended opinion affirming the district court, and denied a
    petition for rehearing en banc on behalf of the court in an
    interlocutory appeal from the district court’s order denying a
    motion to dismiss claims that Google violated the Wiretap
    Act when it collected data from unencrypted Wi-Fi networks
    in the course of capturing its Street View photographs.
    The Wiretap Act imposes liability on a person who
    intentionally intercepts any electronic communication,
    subject to a number of exemptions. In the amended opinion,
    the panel held that data transmitted over a Wi-Fi network is
    not a “radio communication” exempt from the Wiretap Act
    under 18 U.S.C. § 2511(2)(g)(i) as an “electronic
    communication” that is “readily accessible to the general
    public.”

    The panel held that the phrase “radio communication” in
    18 U.S.C. § 2510(16) excludes payload data transmitted over
    a Wi-Fi network, and that as a consequence, the definition of
    “readily accessible to the general public [ ] with respect to a
    radio communication” set forth in § 2510(16) does not apply
    to the exemption for an “electronic communication” that is
    “readily accessible to the general public” under §
    2511(2)(g)(I).

    OPINION
    BYBEE, Circuit Judge:
    In the course of capturing its Street View photographs,
    Google collected data from unencrypted Wi-Fi networks.
    Google publicly apologized, but plaintiffs brought suit under
    federal and state law, including the Wiretap Act, 18 U.S.C.
    § 2511. Google argues that its data collection did not violate
    JOFFE V. GOOGLE, INC.                    5
    the Act because data transmitted over a Wi-Fi network is an
    “electronic communication” that is “readily accessible to the
    general public” and exempt under the Act. 18 U.S.C.
    § 2511(2)(g)(i). The district court rejected Google’s
    argument. In re Google Inc. St. View Elec. Commc’n Litig.,
    
    794 F. Supp. 2d 1067
    , 1073–84 (N.D. Cal. 2011). We affirm.
    I. BACKGROUND
    A. Facts and History
    Google launched its Street View feature in the United
    States in 2007 to complement its Google Maps service by
    providing users with panoramic, street-level photographs.
    Street View photographs are captured by cameras mounted on
    vehicles owned by Google that drive on public roads and
    photograph their surroundings. Between 2007 and 2010,
    Google also equipped its Street View cars with Wi-Fi
    antennas and software that collected data transmitted by Wi-
    Fi networks in nearby homes and businesses. The equipment
    attached to Google’s Street View cars recorded basic
    information about these Wi-Fi networks, including the
    network’s name (SSID), the unique number assigned to the
    router transmitting the wireless signal (MAC address), the
    signal strength, and whether the network was encrypted.
    Gathering this basic data about the Wi-Fi networks used in
    homes and businesses enables companies such as Google to
    provide enhanced “location-based” services, such as those
    that allow mobile phone users to find nearby restaurants and
    attractions or receive driving directions.
    But the antennas and software installed in Google’s Street
    View cars collected more than just the basic identifying
    information transmitted by Wi-Fi networks. They also
    6                     JOFFE V. GOOGLE, INC.
    gathered and stored “payload data” that was sent and received
    over unencrypted Wi-Fi connections at the moment that a
    Street View car was driving by.1 Payload data includes
    everything transmitted by a device connected to a Wi-Fi
    network, such as personal emails, usernames, passwords,
    videos, and documents.
    Google acknowledged in May 2010 that its Street View
    vehicles had been collecting fragments of payload data from
    unencrypted Wi-Fi networks. The company publicly
    apologized, grounded its vehicles, and rendered inaccessible
    the personal data that had been acquired. In total, Google’s
    Street View cars collected about 600 gigabytes of data
    transmitted over Wi-Fi networks in more than 30 countries.
    Several putative class-action lawsuits were filed shortly
    after Google’s announcement, and, in August 2010, the cases
    were transferred by the Judicial Panel on Multidistrict
    Litigation to the Northern District of California. In
    November, 2010, Plaintiffs-Appellees (collectively “Joffe”)
    filed a consolidated complaint, asserting claims against
    Google under the federal Wiretap Act, 18 U.S.C. § 2511;
    California Business and Professional Code § 17200; and
    various state wiretap statutes. Joffe seeks to represent a class
    comprised of all persons whose electronic communications
    were intercepted by Google Street View vehicles since May
    25, 2007.
    Google moved to dismiss Joffe’s consolidated complaint.
    The district court declined to grant Google’s motion to

    Google may have also used its software to capture encrypted data, but
    the plaintiffs have conceded that their wireless networks were
    unencrypted.

    dismiss Joffe’s federal Wiretap Act claims.2 In re Google
    Inc. St. View Elec. Commc’n 
    Litig., 794 F. Supp. 2d at 1084
    .
    On Google’s request, the court certified its ruling for
    interlocutory appeal under 28 U.S.C. § 1292(b) because the
    district court resolved a novel question of statutory
    interpretation. We granted Google’s petition, and we have
    jurisdiction under 28 U.S.C. § 1292(b).
    B. District Court’s Decision
    Google maintained before the district court that it should
    have dismissed Joffe’s Wiretap Act claims because data
    transmitted over unencrypted Wi-Fi networks falls under the
    statutory exemption that makes it lawful to intercept
    “electronic communications” that are “readily accessible to
    the general public.” 18 U.S.C. § 2511(2)(g)(i). The question
    was whether payload data transmitted on an unencrypted Wi-
    Fi network is “readily accessible to the general public,” such
    that the § 2511(2)(g)(i) exemption applies to Google’s
    conduct.
    To answer this question, the district court first looked to
    the definitions supplied by the Act. In re Google Inc. St.
    View Elec. Commc’n 
    Litig., 794 F. Supp. 2d at 1075
    –76. The
    statute provides in relevant part that “‘readily accessible to
    the general public’ means, with respect to a radio
    communication, that such communication is not . . . (A)
    scrambled or encrypted.” 18 U.S.C. § 2510(16). An
    unencrypted radio communication is, therefore, “readily
    2
    The district court granted Google’s motion to dismiss Joffe’s claims
    under California law and other state wiretap statutes. In re Google Inc. St.
    View Elec. Commc’n 
    Litig., 794 F. Supp. 2d at 1085
    –86. These claims are
    not at issue here.
    8                      JOFFE V. GOOGLE, INC.
    accessible to the general public.” In short, intercepting an
    unencrypted radio communication does not give rise to
    liability under the Wiretap Act because of the combination of
    the § 2511(2)(g)(i) exemption and the § 2510(16) definition.
    The district court then considered whether data
    transmitted over a Wi-Fi network is a “radio communication”
    because the phrase is not defined by the Act. In re Google
    Inc. St. View Elec. Commc’n 
    Litig., 794 F. Supp. 2d at 1076
    –81. The court reasoned that “radio communication”
    encompasses only “traditional radio services,” and not other
    technologies that also transmit data using radio waves, such
    as cellular phones and Wi-Fi networks.3 
    Id. at 1079–83.
    Since Wi-Fi networks are not a “radio communication,” the
    definition of “readily accessible to the general public”
    provided by § 2510(16) does not apply because the definition
    is expressly limited to electronic communications that are
    radio communications.
    Finally, the court addressed whether data transmitted over
    unencrypted Wi-Fi networks is nevertheless an “electronic
    communication” that is “readily accessible to the general
    public” under § 2511(2)(g)(i). 
    Id. at 1082–84.
    Although the
    court determined that Wi-Fi networks do not involve a “radio
    communication” under § 2510(16) and are therefore not
    “readily accessible to the general public” by virtue of the
    definition of the phrase, it still had to resolve whether they
    are “readily accessible to the general public” as the phrase is
    ordinarily understood because the statute does not define the
    phrase as it applies to an “electronic communication” that is
    3
    It is less clear whether the district court’s definition also excludes
    television broadcasts. Joffe argued at oral argument that television
    broadcasts are “traditional radio services.”
    JOFFE V. GOOGLE, INC.                    9
    not a “radio communication.” The court reasoned that
    “without more, merely pleading that a network is unencrypted
    does not render that network readily accessible to the general
    public and serve to remove the intentional interception of
    electronic communications from that network from liability
    under the [Electronic Communications Privacy Act].” 
    Id. at 1084.
    The court accordingly declined to grant Google’s
    motion to dismiss Joffe’s Wiretap Act claims. 
    Id. II. OVERVIEW
    OF THE WIRETAP ACT
    The Wiretap Act imposes liability on a person who
    “intentionally intercepts . . . any wire, oral, or electronic
    communication,” 18 U.S.C. § 2511(1)(a), subject to a number
    of exemptions. See 18 U.S.C. § 2511(2)(a)–(h). There are
    two exemptions that are relevant to our purposes. First, the
    Wiretap Act exempts intercepting “an electronic
    communication made through an electronic communication
    system” if the system is configured so that it is “readily
    accessible to the general public.” 18 U.S.C. § 2511(2)(g)(i).
    “Electronic communication” includes communication by
    radio, 18 U.S.C. § 2510(12), and “‘readily accessible to the
    general public’ means, with respect to a radio
    communication” that the communication is “not . . .
    scrambled or encrypted,” 18 U.S.C. § 2510(16)(A). Second,
    the Act exempts intercepting “radio communication” by “any
    station for the use of the general public;” by certain
    governmental communication systems “readily accessible to
    the general public,” including police, fire, and civil defense
    agencies; by a station operating on an authorized frequency
    for “amateur, citizens band, or general mobile radio
    services;” or by a marine or aeronautical communications
    system. 18 U.S.C. § 2511(2)(g)(ii)(I)–(IV).
    10                  JOFFE V. GOOGLE, INC.
    Google only argues, as it did before the district court, that
    it is exempt from liability under the Act because data
    transmitted over a Wi-Fi network is an “electronic
    communication . . . readily accessible to the general public”
    under § 2511(2)(g)(i). It concedes that it does not qualify for
    any of the exemptions for specific types of “radio
    communication” under § 2511(2)(g)(ii). Joffe, however,
    argues that if data transmitted over a Wi-Fi network is not
    exempt as a “radio communication” under § 2511(2)(g)(ii),
    it cannot be exempt as a radio communication under the
    broader exemption for “electronic communication” in
    § 2511(2)(g)(i). This argument has some force, and we wish
    to address it before we consider Google’s claims.
    Joffe contends that the definition of “readily accessible
    to the general public” in § 2510(16) does not apply to
    the § 2511(2)(g)(i) exemption. Instead, Joffe argues,
    the § 2510(16) definition applies exclusively to
    § 2511(2)(g)(ii)(II), which exempts specifically enumerated
    types of “radio communication” when they are “readily
    accessible to the general public.” We ultimately reject Joffe’s
    alternative reading of the statute, although—as we will
    explain—we find § 2511(2)(g)(ii) useful as a lexigraphical
    aid to understanding the phrase “radio communication.”
    As noted, § 2510(16) defines “readily accessible to the
    general public” solely with respect to a “radio
    communication,” and not with respect to other types of
    “electronic communication.” Although § 2511(2)(g)(i) does
    not use the words “radio communication,” the statute
    nevertheless directs us to apply the § 2510(16) definition to
    the § 2511(2)(g)(i) exemption. First, “radio communication”
    is a subset of “electronic communication.” See 18 U.S.C.
    § 2510(12) (providing that, subject to certain exceptions,
    JOFFE V. GOOGLE, INC.                     11
    “‘electronic communication’ means any transfer of signs,
    signals, writing, images, sounds, data, or intelligence of any
    nature transmitted in whole or in part by a wire, radio,
    electromagnetic, photoelectronic or photooptical system”)
    (emphasis added). Second, the statute directs us to apply
    § 2510(16) to the entire chapter. The definitions in 18 U.S.C.
    § 2510 are prefaced with the phrase, “As used in this
    chapter.” We cannot disregard this command by holding that
    the definition of “‘readily accessible to the general public’ [ ]
    with respect to a radio communication” applies to
    § 2511(2)(g)(ii), but not § 2511(2)(g)(i).
    Admittedly, following the plain language of the statute
    creates some tension with § 2511(2)(g)(ii)(II), which provides
    an exemption for intercepting “any radio communication
    which is transmitted . . . by any governmental, law
    enforcement, civil defense, private land mobile, or public
    communications system, including police and fire, readily
    accessible to the general public.” Under our reading of the
    statute—which is the same reading adopted by the district
    court, Google, and Joffe in his lead argument—
    § 2511(2)(g)(i) exempts all electronic communications
    (including radio communications) that are “readily accessible
    to the general public” as the phrase is defined in § 2510(16).
    This reading likely renders § 2511(2)(g)(ii)(II) superfluous.
    As discussed, that section exempts specific kinds of radio
    communications that are “readily accessible to the general
    public,” such as those transmitted by a law enforcement
    communications system. But this exemption is unnecessary
    when § 2511(2)(g)(i) already exempts all radio
    communications that are “readily accessible to the general
    public.”
    12                JOFFE V. GOOGLE, INC.
    Although our reading may render § 2511(2)(g)(ii)(II)
    superfluous or at least redundant, we understand that
    Congress “sometimes drafts provisions that appear
    duplicative of others—simply in Macbeth’s words, ‘to make
    assurance double sure.’ That is, Congress means to clarify
    what might be doubtful—that the mentioned item is covered.”
    Shook v. D.C. Fin. Responsibility & Mgmt. Assistance Auth.,
    
    132 F.3d 775
    , 782 (D.C. Cir. 1998). This interpretation is
    especially plausible given that Congress was concerned that
    radio hobbyists not face liability for intercepting readily
    accessible broadcasts, such as those covered by
    § 2511(2)(g)(ii)(II), which can be picked up by a police
    scanner. See 132 Cong. Rec. S7987-04 (1986) (“In order to
    address radio hobbyists’ concerns, we modified the original
    language of S. 1667 to clarify that intercepting traditional
    radio services is not unlawful.”).
    In short, we agree with Google that the definition of
    “readily accessible to the general public” in § 2510(16)
    applies to the § 2511(2)(g)(i) exemption when the
    communication in question is a “radio communication.”
    With that understanding, we now turn to whether data
    transmitted over a Wi-Fi network is a “radio communication”
    exempt from the Wiretap Act as an “electronic
    communication” under § 2511(2)(g)(i).
    III. ANALYSIS
    Google contends that data transmitted over a Wi-Fi
    network is a “radio communication” and that the Act exempts
    such communications by defining them as “readily accessible
    to the general public,” 18 U.S.C. § 2511(2)(g)(i), so long as
    “such communication is not . . . scrambled or encrypted,”
    JOFFE V. GOOGLE, INC.                           13
    18 U.S.C. § 2510(16)(A). We reject this claim.4 We hold
    that the phrase “radio communication” in 18 U.S.C.
    § 2510(16) excludes payload data transmitted over a Wi-Fi
    network. As a consequence, the definition of “readily
    accessible to the general public [ ] with respect to a radio
    communication” set forth in § 2510(16) does not apply to the
    exemption for an “electronic communication” that is “readily
    accessible to the general public” under 18 U.S.C.
    § 2511(2)(g)(i).
    A. The Ordinary Meaning of “Radio Communication” Does
    Not Include Data Transmitted over a Wi-Fi Network
    The Wiretap Act does not define the phrase “radio
    communication” so we must give the term its ordinary
    meaning. See Hamilton v. Lanning, 
    130 S. Ct. 2464
    , 2471
    (2010) (“When terms used in a statute are undefined, we give
    them their ordinary meaning.”); United States v. Daas,
    
    198 F.3d 1167
    , 1174 (9th Cir. 1999) (“If the statute uses a
    term which it does not define, the court gives that term its
    ordinary meaning.”).
    According to Google, radio communication “refers to any
    information transmitted using radio waves, i.e., the radio
    frequency portion of the electromagnetic spectrum.”
    Appellant’s Br. at 28. The radio frequency portion of the
    4
    This case raises a question of statutory interpretation, which we review
    de novo. Phoenix Mem'l Hosp. v. Sebelius, 
    622 F.3d 1219
    , 1224 (9th Cir.
    2010). We begin by “determin[ing] whether the language at issue has a
    plain and unambiguous meaning with regard to the particular dispute in
    the case.” Barnhart v. Sigmon Coal Co., 
    534 U.S. 438
    , 450 (2002). We
    must assume that “the ordinary meaning of that language accurately
    expresses the legislative purpose [of Congress].” Park 'N Fly, Inc. v.
    Dollar Park & Fly, Inc., 
    469 U.S. 189
    , 194 (1985).

    spectrum is “the part of the spectrum where electromagnetic
    waves have frequencies in the range of about 3 kilohertz to
    300 gigahertz.” 
    Id. at 27.
    Google’s technical definition does not conform with the
    common understanding held contemporaneous with the
    enacting Congress. See United States v. Iverson, 
    162 F.3d 1015
    , 1022 (9th Cir. 1998) (“When a statute does not define
    a term, we generally interpret that term by employing the
    ordinary, contemporary, and common meaning of the words
    that Congress used”) (emphasis added). The radio frequency
    portion of the electromagnetic spectrum covers not only Wi-
    Fi transmissions, but also television broadcasts, Bluetooth
    devices, cordless and cellular phones, garage door openers,
    avalanche beacons, and wildlife tracking collars. See Fed.
    Commc’n Comm’n, Encyclopedia – FM Broadcast Station
    Classes and Service Countours, available at
    http://www.ntia.doc.gov/files/ntia/publications/2003-
    allochrt.pdf (last visited Aug. 13, 2013). One would not
    ordinarily consider, say, television a form of “radio
    communication.” Not surprisingly, Congress has not
    typically assumed that the term “radio” encompasses the term
    “television.” See, e.g., 18 U.S.C. § 1343 (imposing liability
    for “[f]raud by wire, radio, or television”) (emphasis added);
    18 U.S.C. § 2101 (imposing liability for inciting a riot by
    means of “mail, telegraph, radio, or television”) (emphasis
    added); 7 U.S.C. § 2156 (defining an “instrumentality of
    interstate commerce” as “any written, wire, radio, television
    or other form of communication); see also FCC v. Nat'l
    Citizens Comm. for Broad., 
    436 U.S. 775
    , 815 (1978) (noting
    that “radio and television stations are given different weight,”
    under the regulations at issue, and describing regulations
    governing “a radio or television broadcast station”) (emphasis
    added).

    The Wiretap Act itself does not assume that the phrase
    “radio communication” encompasses technologies like
    satellite television that are outside the scope of the phrase as
    it is ordinarily defined. For example, the statute’s damages
    provision sets out specified penalties when the “violation of
    this chapter is the private viewing of a private satellite video
    communication that is not scrambled or encrypted or if the
    communication is a radio communication that is transmitted
    on [frequencies specified by regulation].” 18 U.S.C.
    § 2520(c)(1) (emphasis added).             Congress described
    separately the act of “viewing [ ] a private satellite video
    communication” even though such communication is
    transmitted on a radio frequency and would fall within
    Google’s proposed definition of “radio communication.”
    Taken together, these disparate provisions offer evidence that
    Congress does not use “radio” or “radio communication” to
    reference all of the myriad forms of communication that use
    the radio spectrum. Rather, it uses “radio” to refer to
    traditional radio technologies, and then separately describes
    other modes of communication that are not ordinarily thought
    of as radio, but that nevertheless use the radio spectrum.
    Google’s proposed definition is in tension with how
    Congress—and virtually everyone else—uses the phrase. In
    common parlance, watching a television show does not entail
    “radio communication.” Nor does sending an email or
    viewing a bank statement while connected to a Wi-Fi
    network. There is no indication that the Wiretap Act carries
    a buried implication that the phrase ought to be given a
    broader definition than the one that is commonly understood.
    See Mohamad v. Palestinian Auth., 
    132 S. Ct. 1702
    , 1707
    (2012) (favoring a definition that matches “how we use the
    word in everyday parlance” and observing that “Congress
    remains free, as always, to give the word a broader or
    16                 JOFFE V. GOOGLE, INC.
    different meaning. But before we will assume it has done so,
    there must be some indication Congress intended such a
    result”).
    Importantly, Congress provided definitions for many
    other similar terms in the Wiretap Act, but refrained from
    providing a technical definition of “radio communication”
    that would have altered the notion that it should carry its
    common, ordinary meaning. See, e.g., 18 U.S.C. § 2510(1)
    (defining “wire communication”); 18 U.S.C. § 2510(12)
    (defining “electronic communication”); 18 U.S.C. § 2510(15)
    (defining “electronic communication service”); 18 U.S.C.
    § 2510(17) (defining “electronic storage”). As Google writes
    in its brief, “[t]he fact that the Wiretap Act provides
    specialized definitions for certain compound terms—but not
    for ‘radio communication’—is powerful evidence that the
    undefined term was not similarly intended [to] be defined in
    a specialized or narrow way” but rather “according to its
    ordinary meaning.” Appellant’s Br. at 29. We agree and,
    accordingly, we reject Google’s proposed definition of “radio
    communication” in favor of one that better reflects the
    phrase’s ordinary meaning.
    B. A “Radio Communication” is a Predominantly Auditory
    Broadcast, Which Excludes Payload Data Transmitted
    over Wi-Fi Networks
    There are two telltale indicia of a “radio communication.”
    A radio communication is commonly understood to be (1)
    predominantly auditory, and (2) broadcast. Therefore,
    television—whether connected via an indoor antenna or a
    satellite dish—is not radio, by virtue of its visual component.
    A land line phone does not broadcast, and, for that reason, is
    not radio. On the other hand, AM/FM, Citizens Band (CB),
    JOFFE V. GOOGLE, INC.                          17
    ‘walkie-talkie,’ and shortwave transmissions are
    predominantly auditory, are broadcast, and are, not
    coincidentally, typically referred to as “radio” in everyday
    parlance. Thus, we conclude that “radio communication”
    should carry its ordinary meaning: a predominantly auditory
    broadcast.5
    The payload data transmitted over unencrypted Wi-Fi
    networks that was captured by Google included emails,
    usernames, passwords, images, and documents that cannot be
    classified as predominantly auditory. They therefore fall
    outside of the definition of a “radio communication” as the
    phrase is used in 18 U.S.C. § 2510(16).
    5
    We need not reach the question of what exactly constitutes a
    “broadcast” because the Wi-Fi transmissions in question were not
    predominantly auditory. Whether cell phone calls—which are projected
    wirelessly over great distances—are broadcast would similarly be a close
    question.
    We also need not fully consider the extent to which non-auditory
    transmissions may be included in a broadcast before that broadcast is no
    longer a radio broadcast. Modern FM radio stations, for example,
    commonly transmit small amounts of data denoting the artist and title of
    the song. But because such data is ancillary to the audio transmission,
    they likely do not remove the transmissions from the domain of a “radio
    communication” under the Act.
    And, finally, we do not address how to classify a traditional radio
    broadcast delivered to a web-enabled device connected to a Wi-Fi
    network, such as a radio station streamed over the internet. Here,
    Google’s collection efforts were not limited to auditory transmissions.

    C. Defining “Radio Communication” to Include Only
    Predominantly Auditory Broadcasts is Consistent with the
    Rest of the Wiretap Act
    Crucially, defining “radio communication” as a
    predominantly auditory broadcast yields a coherent and
    consistent Wiretap Act. Google’s overly broad definition
    does not. See K Mart Corp. v. Cartier, Inc., 
    486 U.S. 281
    ,
    291 (1988) (“In ascertaining the plain meaning of the statute,
    the court must look to the particular statutory language at
    issue, as well as the language and design of the statute as a
    whole.”)
    Throughout the Wiretap Act, Congress used the phrase
    “radio communication”—which is at issue here—and the
    similar phrase “communication by radio.” Even within the
    very provision that we are construing—18 U.S.C.
    § 2510(16)—Congress used both phrases. We must ascribe
    to each phrase its own meaning. See SEC v. McCarthy,
    
    322 F.3d 650
    , 656 (9th Cir. 2003) (“It is a well-established
    canon of statutory interpretation that the use of different
    words or terms within a statute demonstrates that Congress
    intended to convey a different meaning for those words.”).
    The phrase “communication by radio” is used more
    expansively: it conjures an image of all communications
    using radio waves or a radio device. See, e.g., 18 U.S.C.
    § 2510(16)(E) (describing radio communication that “is a
    two-way voice communication by radio transmitted on a
    frequency “not exclusively allocated to broadcast auxiliary
    services.”).
    When read in context, the phrase “radio communication”
    tends to refer more narrowly to broadcast radio technologies
    rather than to the radio waves by which the communication
    JOFFE V. GOOGLE, INC.                    19
    is made. “Radio communication” is typically surrounded by
    words that evoke traditional radio technologies whenever it
    is used in the Act. See Gustafson v. Alloyd Co., 
    513 U.S. 561
    ,
    575 (1995) (“”[A] word is known by the company it keeps
    (the doctrine of noscitur a sociis). This rule we rely upon to
    avoid ascribing to one word a meaning so broad that it is
    inconsistent with its accompanying words, thus giving
    ‘unintended breadth to the Acts of Congress.’”). For
    example, 18 U.S.C. § 2511(2)(g)(ii), inter alia, exempts from
    liability the interception of “any radio communication which
    is transmitted . . . by a station operating on an authorized
    frequency within the bands allocated to the amateur, citizens
    band, or general mobile radio services.” These are traditional
    audio broadcasts that fit squarely within the ordinary meaning
    of “radio communication.”               The phrase “radio
    communication” is used five times in the Wiretap Act. See
    18 U.S.C. § 2510(16), 18 U.S.C. § 2511(2)(g)(ii), 18 U.S.C.
    § 2511(2)(g)(v), 18 U.S.C. § 2511(5)(a)(i)(B), 18 U.S.C
    § 2520(c)(1). Defining the term as a predominantly auditory
    broadcast would not distort the meaning of any of these
    provisions or otherwise lead to incoherence or inconsistency.
    On the other hand, the Wiretap Act uses “communication
    by radio” to refer more broadly to any communication
    transmitted by radio wave. See 18 U.S.C. § 2510(12)
    (defining “electronic communication” to include any
    communication “transmitted in whole or in part by . . .
    radio”); 18 U.S.C. § 2511(1)(b)(ii) (prohibiting the use of a
    “device to intercept any oral communication” if the “device
    transmits communications by radio”); 18 U.S.C. § 2511(2)(b)
    (authorizing FCC employees, in carrying out their official
    duties, “to intercept . . . [an] oral communication transmitted
    by radio”). Congress’s decision to use both of these phrases
    implies that it intended to distinguish “radio communication”
    20                 JOFFE V. GOOGLE, INC.
    from “communications by radio.” See 
    McCarthy, 322 F.3d at 656
    . Ideally, Congress would have supplied definitions to
    make the distinction between these terms more apparent.
    Nevertheless, by relying on their ordinary meaning and
    evaluating how they are used in context, we conclude that the
    former refers more narrowly to a predominantly auditory
    broadcast while only the latter encompasses other
    communications made using radio waves.
    The way the phrase “radio communication” is used in
    18 U.S.C. § 2511(2)(g)(ii) is particularly relevant in defining
    the term because that provision specifically exempts from
    liability the interception of certain kinds of radio
    communication. The provision is not directly at issue here
    because—as Google acknowledges—Google’s conduct is not
    encompassed by any of the § 2511(2)(g)(ii) exemptions,
    hence its reliance on § 2511(2)(g)(i). But it is instructive to
    understand the types of communication exempted by
    § 2511(2)(g)(ii) since the phrase “radio communication” is
    “known by the company it keeps,” 
    Gustafson, 513 U.S. at 575
    .      The exemptions include, inter alia, radio
    communications transmitted “by any station for the use of the
    general public,” 18 U.S.C. § 2511(2)(g)(ii)(I), “by a station
    operating on an authorized frequency within the bands
    allocated to the amateur, citizens band, or general mobile
    radio services,” 18 U.S.C. § 2511(2)(g)(ii)(III), and “by any
    marine or aeronautical communications system,” 18 U.S.C.
    § 2511(2)(g)(ii)(IV). Other than the fact that they all use the
    radio spectrum, these radio communications have little in
    common with a home Wi-Fi network.                   Of course
    § 2511(2)(g)(i) exempts radio communications that are
    “readily accessible to the general public” even if they are not
    specifically set out in § 2511(2)(g)(ii). But it would be odd
    for Congress to take pains to identify particular kinds of radio
    JOFFE V. GOOGLE, INC.                     21
    communications that should be exempt in § 2511(2)(g)(ii)
    only to exempt broad swaths of dissimilar communications,
    such as data transmitted over a Wi-Fi network, under the
    auspices of § 2511(2)(g)(i). It is more sensible to read the
    general exemption in § 2511(2)(g)(i)—insofar as it applies to
    “radio communication” rather than other kinds of “electronic
    communication”—in light of the specific exemptions in
    § 2511(2)(g)(ii).
    Relatedly, giving “radio communication” its ordinary
    meaning as a predominantly auditory broadcast also avoids
    producing absurd results that are inconsistent with the
    statutory scheme. See Griffin v. Oceanic Contractors, Inc.,
    
    458 U.S. 564
    , 575 (1982) (“[I]nterpretations of a statute
    which would produce absurd results are to be avoided if
    alternative interpretations consistent with the legislative
    purpose are available.”); Ariz. State Bd. for Charter Schools
    v. U.S. Dep’t of Educ., 
    464 F.3d 1003
    , 1008 (9th Cir. 2006)
    (“[W]ell-accepted rules of statutory construction caution us
    that ‘statutory interpretations which would produce absurd
    results are to be avoided.’ When a natural reading of the
    statutes leads to a rational, common-sense result, an alteration
    of meaning is not only unnecessary, but also extrajudicial.”).
    Under the expansive definition of “radio communication”
    proposed by Google, the protections afforded by the Wiretap
    Act to many online communications would turn on whether
    the recipient of those communications decided to secure her
    wireless network. A “radio communication” is “readily
    accessible to the general public” and, therefore, exempt from
    Wiretap Act liability if it is not scrambled or encrypted.
    18 U.S.C. § 2510(16). Consider an email attachment
    containing sensitive personal information sent from a secure
    Wi-Fi network to a doctor, lawyer, accountant, priest, or
    spouse. A company like Google that intercepts the contents
    22                 JOFFE V. GOOGLE, INC.
    of that email from the encrypted home network has, quite
    understandably, violated the Wiretap Act. But the sender of
    the email is in no position to ensure that the recipient—be it
    a doctor, lawyer, accountant, priest, or spouse—has taken
    care to encrypt her own Wi-Fi network. Google, or anyone
    else, could park outside of the recipient’s home or office with
    a packet sniffer while she downloaded the attachment and
    intercept its contents because the sender’s “radio
    communication” is “readily accessible to the general public”
    solely by virtue of the fact that the recipient’s Wi-Fi network
    is not encrypted. Surely Congress did not intend to condone
    such an intrusive and unwarranted invasion of privacy when
    it enacted the Wiretap Act “to protect against the
    unauthorized interception of electronic communications.”
    S. Rep. No. 99-541 (1986), at 1; see also Konop v. Hawaiian
    Airlines, Inc., 
    302 F.3d 868
    , 875 (9th Cir. 2002) (“The
    legislative history of the [Wiretap Act] suggests that
    Congress wanted to protect electronic communications that
    are configured to be private, such as email.”); In re
    Pharmatrak, Inc. Privacy Litig., 
    329 F.3d 9
    , 18 (1st Cir.
    2003) (“The paramount objective of the Wiretap Act is to
    protect effectively the privacy of communications.”).
    The definition of “readily accessible to the general
    public” in § 2510(16) is limited to “radio communication,”
    and does not encompass all “electronic communication.”
    Congress’s decision to carve out “radio communication” for
    less protection than some other types of “electronic
    communication” makes sense if “radio communication” is
    given its ordinary meaning. Traditional radio services can be
    easily and mistakenly intercepted by hobbyists. See 132
    Cong. Rec. S7987-04 (1986) (“In order to address radio
    hobbyists’ concerns, we modified the original language of
    S. 1667 to clarify that intercepting traditional radio services
    JOFFE V. GOOGLE, INC.                     23
    is not unlawful.”). But “radio hobbyists” do not mistakenly
    use packet sniffers to intercept payload data transmitted on
    Wi-Fi networks. Lending “radio communication” a broad
    definition that encompasses data transmitted on Wi-Fi
    networks would obliterate Congress’s compromise and create
    absurd applications of the exemption for intercepting
    unencrypted radio communications.               For example,
    § 2511(2)(g)(ii)(II) exempts from liability, inter alia, the act
    of intercepting “any radio communication which is
    transmitted . . . by any governmental, law enforcement . . . or
    public safety communications system, including police and
    fire, readily accessible to the general public.” This provision
    reinforces the work performed by § 2511(2)(g)(i), which
    already exempts a “radio communication” that is “readily
    accessible to the general public.” Congress’s decision to
    ensure that these communications were exempt makes sense
    if “radio communication” encompasses only predominantly
    auditory broadcasts since these transmissions can be picked
    up by widely available police scanners. But if “radio
    communication” includes data transmitted over Wi-Fi
    networks, then § 2511(2)(g)(ii)(II) also underscores that
    liability should not attach to intercepting data from an
    unencrypted Wi-Fi network operated by, say, a police
    department or government agency. It seems doubtful that
    Congress wanted to emphasize that Google or anyone else
    could park outside of a police station that carelessly failed to
    secure its Wi-Fi network and intercept confidential data with
    impunity.
    Next, Google strenuously argues that the rest of the
    Wiretap Act supports its position that “radio communication”
    in 18 U.S.C. § 2510(16) means “any information transmitted
    using radio waves.” Google leans heavily on § 2510(16)(D)
    and the accompanying legislative history, which together
    24                 JOFFE V. GOOGLE, INC.
    suggest that cellular telephone and paging systems are a form
    of “radio communication.” If cell phone and paging systems
    are a type of “radio communication,” Google argues, it must
    be the case that Congress intended that the phrase include Wi-
    Fi networks and the rest of the radio spectrum because these
    technologies differ from paradigmatic radio communications
    like AM/FM, CB, and shortwave transmissions. But cell
    phone communications were not dissimilar from CB,
    shortwave, or other two-way forms of traditional radio
    broadcasts when § 2510(16)(D) was added to the Wiretap Act
    in 1986 as part of the Electronic Communications Privacy
    Act, Pub. L. No. 99-508, 100 Stat. 1848. When Congress
    enacted § 2510(16)(D), cell phones were still called “cellular
    radiotelephones.” See H.R. Rep. No. 99-647, at 20 (1986).
    As with other audio broadcasts, cellular conversations were
    often inadvertently picked up by radio hobbyists “scanning
    radio frequencies in order to receive public communications.”
    S. Rep. No. 99-541, at 3560 (1986); see also H.R. Rep. No.
    99-647, at 20 (“Cellular telephone calls can be intercepted by
    either sophisticated scanners designed for that purpose, or by
    regular radio scanners modified to intercept cellular calls”).
    The fact that technology has evolved and cellular
    communications are no longer as similar to CB broadcasts as
    they once were does not require us to read “radio
    communication” to include all communications made using
    radio waves. Rather, the historical context surrounding
    Congress’s protection of cellular conversations as a form of
    a “radio communication” is consistent with the commonsense
    definition of the term because, at the time of the enactment of
    the definition in 1986, cellular conversations could have
    reasonably been construed as analogous to a form of two-way
    JOFFE V. GOOGLE, INC.                           25
    radio.6 Assuming, arguendo, that the phrase “radio
    communication” covers cell phone transmissions as they
    existed in 1986 does not inevitably lead to the conclusion that
    it also encompasses transmissions that are plainly not
    predominantly auditory broadcasts, such as payload data
    transmitted over a Wi-Fi network.
    Google also looks beyond the Wiretap Act in an effort to
    fit its expansive definition of “radio communication” into the
    statutory scheme. It points out that the Communications Act
    expressly defines the phrases “radio communication” and
    “communication by radio” broadly to include “the
    transmission by radio of writing, signs, signals, pictures, and
    sounds of all kinds.” 47 U.S.C. § 153(40). But when
    Congress wanted to borrow a definition from the
    Communications Act to apply to the Wiretap Act, it expressly
    said so. See 18 U.S.C. § 2510(1) (giving the phrase
    “communication common carrier” the meaning that it has “in
    section 3 of the Communications Act”). Here, Congress
    refrained from incorporating the definition of “radio
    6
    With modern advances in cellular technology, it is less clear how cell
    phones would fit within the statutory scheme today. We need not resolve
    this question here. Whether cell phone transmissions are an example of
    a “radio communication” is relevant to defining the phrase, but it is not a
    precursor to observing that a “radio communication” is ordinarily a
    predominantly auditory broadcast or to holding that payload data
    transmitted over a Wi-Fi network is not a “radio communication.” We
    previously held that cell phone communications are “wire
    communications” for purposes of the Wiretap Act, but we did not address
    whether they are an example of a “radio communication.” See In re U.S.
    for an Order Authorizing Roving Interception of Oral Commc'ns, 
    349 F.3d 1132
    , 1138 n.12 (9th Cir. 2003) (“Despite the apparent wireless nature of
    cellular phones, communications using cellular phones are considered
    wire communications under the statute, because cellular telephones use
    wire and cable connections when connecting calls.”).
    26                JOFFE V. GOOGLE, INC.
    communication” used in the Communications Act. And, as
    previously discussed, the Wiretap Act uses the phrases “radio
    communication” and “communication by radio” differently,
    indicating that Congress did not intend to import the
    Communications Act’s definition, which treats them as
    synonyms. See 47 U.S.C. § 153(40). Furthermore, the
    Communication Act’s definition of “radio communication”
    encompasses technologies like television by including “the
    transmission by radio of . . . pictures . . . of all kinds,”
    47 U.S.C. § 153(40), while the Wiretap Act sometimes
    distinguishes them. See, e.g., 18 U.S.C. § 2520(c)(1)
    (providing specified penalties when the “violation of this
    chapter is the private viewing of a private satellite video
    communication that is not scrambled or encrypted or if the
    communication is a radio communication that is transmitted
    on [frequencies specified by regulation]”).         Separate
    references to television-related communications would be
    redundant when paired with the phrase “radio
    communication” if we were to assume that the
    Communication Act’s definition applied to the Wiretap Act.
    Importantly, the presumption that a definition set out in one
    part of the code is intended to govern another is hardly
    unyielding in the face of such contradictory evidence. See,
    e.g., General Dynamics Land Sys., Inc. v. Cline, 
    540 U.S. 581
    , 595 (2004) (holding that the word “age” carries a
    different meaning in different sections of the ADEA);
    Robinson v. Shell Oil, 
    519 U.S. 337
    , 343 (1997) (holding that
    the term “employees” carries a different meaning in different
    sections of Title VII).
    Google also leans heavily on a series of amendments to
    18 U.S.C. § 2510(16) to argue that Congress impliedly gave
    the phrase “radio communication” a meaning other than the
    ordinary one that we adopt here. In 1990, Senator Patrick
    JOFFE V. GOOGLE, INC.                     27
    Leahy commissioned a task force to study the effect of new
    technologies, including the precursors to wireless networking,
    on the statutory scheme created in 1986 by the Electronic
    Communications Privacy Act. See S. Hrg. 103-1022, at 179
    (1994). In its report, the task force indicated it was concerned
    that communications by “‘wireless modems’ which can
    transmit data between computers . . . will not be protected
    unless the user goes to the expense of full data encryption.”
    
    Id. at 183.
    The section of the report on “Wireless Data
    Communications” concluded that “[t]he task force
    recommends appropriate amendments to legally protect
    digital communications of this type from unauthorized
    interception.” 
    Id. In short,
    the task force was of the opinion
    that the version of 18 U.S.C. § 2510(16) enacted in 1986 did
    not adequately protect unencrypted “wireless data
    communications.” The task force must have implicitly
    decided that “wireless data communications” were a “radio
    communication” because otherwise it would not have been
    concerned with § 2510(16), which only applies to “radio
    communication.” See 
    id. In 1994,
    Congress amended § 2510(16) to add a new
    category of communication—which it called an “electronic
    communication”—that it deemed to be a “radio
    communication” that was not “readily accessible to the
    general public.” In relevant part, the statute provided that
    “‘readily accessible to the general public’ means, with respect
    to a radio communication, that such communication is not . . .
    (F) an electronic communication.” 18 U.S.C. § 2510(16)
    (1994). Google claims that Congress added § 2510(16)(F) in
    1994 in order to protect from interception new technologies
    that transmitted data using radio frequencies, including the
    contemporary versions of wireless networks. There is some
    support for this proposition in the congressional record. See
    28                 JOFFE V. GOOGLE, INC.
    H.R. Rep. No. 103-827, at 18 (1994) (explaining that the bill
    “[e]xtends privacy protections of the Electronic
    Communications Privacy Act to cordless phones and certain
    data communications transmitted by radio”).
    The significance of all of this is that Congress repealed
    18 U.S.C. § 2510(16)(F) in 1996. Google attempts to draw a
    series of inferences from the 1994 and 1996 amendments:
    The 1994 Congress thought that data transmissions across the
    wireless networks of the day were a type of “radio
    communication.” Otherwise, Congress would not have
    needed to amend § 2510(16) in order to shield them from
    interception given that the provision only applies to “radio
    communication.” By deleting § 2510(16)(F), the 1996
    Congress removed the sole protection for unencrypted data
    transmissions over wireless networks by returning § 2510(16)
    to its pre-amendment form. From Google’s perspective, the
    upshot of this historical narrative is that payload data
    transmitted over an unencrypted Wi-Fi network is a “radio
    communication” that is “readily accessible to the general
    public” before the 1994 amendment and, crucially, after the
    1996 repeal.
    This evidence of congressional action and inaction is far
    more equivocal than Google acknowledges. First, the task
    force’s report does not control what the phrase “radio
    communication” meant to Congress when it enacted
    § 2510(16) in 1986. The task force’s report suggests that it
    thought that the “wireless data communication” technology
    that existed in 1991 entailed “radio communication” as the
    phrase is used in § 2510(16). But the task force’s opinion on
    questions of statutory interpretation has no independent
    authority; it is not charged with divining congressional intent.
    The task force’s recommendation informs us that in 1991 a
    JOFFE V. GOOGLE, INC.                   29
    group of fifteen individuals thought that early versions of
    wireless networks involved “radio communication” under the
    statute. Their opinion is not indicative of what Congress
    intended when it included the phrase in the Wiretap Act. It
    may be considered evidence of the phrase’s ordinary
    meaning. But it does not outweigh the more substantial
    evidence, discussed at length above, indicating that the
    ordinary meaning of “radio communication” excludes data
    transmitted over a Wi-Fi network.
    Second, Congress’s decision to add § 2510(16)(F) in 1994
    does not prove that it thought data transmitted over a Wi-Fi
    network constituted a “radio communication.” The 1994
    Congress was certainly concerned about ensuring that
    “certain data communications transmitted by radio” were
    protected from interception. But that does not necessarily
    mean that it was of the view that such communications were
    a “radio communication” under § 2510(16). Congress might
    have been forestalling the possibility that evolving
    technologies would be construed as radio communications,
    contrary to the ordinary meaning of the phrase.
    Third, and perhaps most importantly, there is no reliable
    indication of what the 1996 Congress intended to accomplish
    by repealing § 2510(16)(F). Google mines the 1991 task
    force report and the 1994 congressional record, but it cannot
    close the loop on its argument because the 1996 Congress did
    not leave behind the snippets of enactment history that are
    essential to Google’s narrative. Consider two possible
    rationales for the 1996 repeal of § 2510(16)(F): first,
    Congress might have deleted the provision because it found
    it redundant. That is, Congress might have thought that data
    transmitted over a radio frequency was not a “radio
    communication,” which would render the additional
    30                 JOFFE V. GOOGLE, INC.
    protection for such communications offered by § 2510(16)(F)
    unnecessary.
    Alternatively, Congress might have (correctly)
    determined that § 2510(16)(F) made the statute incoherent.
    Recall that the short-lived provision provided that “‘readily
    accessible to the general public’ means, with respect to a
    radio communication, that such communication is not . . . (F)
    an electronic communication.” 18 U.S.C. § 2510(16)(F)
    (1994). The phrase “electronic communication” has been
    broadly defined since the Electronic Communications Privacy
    Act of 1986. In 1994, when § 2510(16)(F) was added, the
    Wiretap Act provided—as it still does today—that
    “‘electronic communication’ means any transfer of signs,
    signals, writing, images, sounds, data, or intelligence of any
    nature transmitted in whole or in part by a wire, radio,
    electromagnetic, photoelectronic or photooptical system that
    affects interstate commerce.” 18 U.S.C. § 2510(12). As
    Google stresses in its briefs, and the statute plainly states,
    “radio communication” is a subset of “electronic
    communication.” Yet § 2510(16)(F) conveyed that a “radio
    communication” was not “readily accessible to the general
    public” if it was an “electronic communication,” which
    incoherently implies that the latter was a subset of the former.
    The repeal of § 2510(16)(F) could, therefore, have been a
    housekeeping matter designed to resolve this internal tension
    without affecting the protection afforded “electronic
    communications, including data” that the 1994 Congress
    sought to protect.
    Neither of these entirely plausible explanations for the
    amendment and repeal are consistent with Google’s
    assumption that the pre-1994 conception of “radio
    communication” included data transmitted over a Wi-Fi
    JOFFE V. GOOGLE, INC.                     31
    network and the 1996 repeal of § 2510(16)(F) sought to
    restore that conception. The point is that we do not know
    why the 1996 Congress deleted § 2510(16)(F). We choose to
    rely on the ordinary meaning of the phrase “radio
    communication” rather than follow a trail of enactment
    history that culminates in silence and then speculate as to
    Congress’s unexpressed intent.
    Finally, Google’s fall back position is that the rule of
    lenity dictates that we accept its proposed definition of “radio
    communication.” Although this is a civil suit, the Wiretap
    Act also carries criminal penalties so Google’s reliance on the
    rule of lenity is not unfounded. See Leocal v. Ashcroft,
    
    543 U.S. 1
    , 11 n.8 (2004) (“Because we must interpret the
    statute consistently, whether we encounter its application in
    a criminal or noncriminal context, the rule of lenity
    applies.”). But we do not resort to the rule of lenity every
    time a difficult question of statutory interpretation arises.
    Rather, “the rule of lenity only applies if, after considering
    text, structure, history, and purpose, there remains a ‘grievous
    ambiguity or uncertainty in the statute.’” Barber v. Thomas,
    
    130 S. Ct. 2499
    , 2508 (2010) (citations omitted); see also
    Smith v. United States, 
    508 U.S. 223
    , 239 (1993) (“The mere
    possibility of articulating a narrower construction [ ] does not
    make the rule of lenity applicable. Instead, that venerable
    rule is reserved for cases where, ‘[a]fter “seizing every thing
    from which aid can be derived,”’ the Court is ‘left with an
    ambiguous statute.’”) (citations omitted).             Here, the
    traditional tools of statutory interpretation are sufficient. The
    ordinary meaning of “radio communication” is consistent
    with the structure of the Act and avoids absurd results without
    running afoul of any clearly expressed congressional intent.
    We need not resort to the rule of lenity where, as here, the
    ambiguity can be fairly resolved.

    IV. CONCLUSION
    For the foregoing reasons, we agree with the district court
    that data transmitted over a Wi-Fi network is not a “radio
    communication” under 18 U.S.C. § 2510(16).
    AFFIRMED.
