`Although the preamble to Claim 1 does not limit the scope of the claim, the preamble describes
`T-Mobile’s wireless networks and related devices, as outlined below.
`T-Mobile makes, uses, sells, or offers to sell wireless network services and wireless networking
`equipment that operates according to standards, including 3G UMTS, 3G EVDO, 3G HSPA+, 4G
`LTE, 4G LTE-Advanced, and IEEE 802.11 a, b, g, n, and ac (“T-Mobile wireless networks”). These
`technologies are standardized by bodies, such as 3GPP and IEEE, and rely on electromagnetic radio
`frequencies to transmit voice and data. These networks implement methods of operating a plurality of
`paging carriers in a single mask-defined, bandlimited channel.
`The following is a non-exhaustive list of exemplary Accused Products: all devices supporting
`802.11n/ac that implement multiple subcarriers, including:

`from the base station and sends it over many parallel sub-carriers, which operate at different
`frequencies all within one assigned channel. These OFDM sub-carriers are the claimed plurality of
`paging carriers. In addition, channels, such as the Physical Downlink Shared Channel (PDSCH) in the
`LTE specification, carry paging messages to mobile devices to alert them of incoming calls. PDSCH

`Wireless operators, including T-Mobile, must operate their radio equipment consistent with FCC
`requirements. The FCC requires, for example, that the waveform output of transmitters conform to
`emission masks, which are intended to reduce adjacent-channel interference. Masks require the power
`spectral density to be attenuated at the band edge.

`LTE specifications define the following:22
`Channel edge: The lowest and highest frequency of the carrier, separated by the channel bandwidth.
`Channel bandwidth: The RF bandwidth supporting a single E-UTRA RF carrier with the
`transmission bandwidth configured in the uplink or downlink of a cell. The channel bandwidth is
`measured in MHz and is used as a reference for transmitter and receiver RF requirements.
`Occupied bandwidth: The width of a frequency band such that, below the lower and above the upper
`frequency limits, the mean powers emitted are each equal to a specified percentage β/2 of the total
`mean power of a given emission.
`Reference bandwidth: The bandwidth in which an emission level is specified.
`Transmission bandwidth: Bandwidth of an instantaneous transmission from a UE or BS, measured in
`Resource Block units.
`Transmission bandwidth configuration: The highest transmission bandwidth allowed for uplink or
`downlink in a given channel bandwidth, measured in Resource Block units.

`802.11 channels are masked-defined, bandlimited channels. 802.11 devices operate within unlicensed
`spectrum called the Industrial, Scientific and Medical (ISM) bands.40 Part 15 of the FCC Rules sets
`aside these bands in the United States for industrial, scientific, and medical equipment. The IEEE
`802.11 specification follows FCC guidelines to regulate radio operations and channel usage within the
`ISM bands.

`In a 10 MHz band, for example, the base station transmits using 50 resource blocks (600 subcarriers),
`giving a transmission bandwidth of 9.015 MHz. This leaves room for 0.5 MHz guard bands,
`approximately 200 guard subcarriers, at the upper and lower edges of the frequency band, which
`minimize the amount of interference with the next band along.70
`Therefore the claimed frequency distance between the center frequency of the outermost carrier and
`the band edge is more than half of the difference between center frequencies of each adjacent carrier.
`In the case of a 10 MHz channel, the frequency distance between the outermost used sub-carrier is 0.5
`MHz, which is more than one-half the 15 kHz subcarrier spacing.71
