The ID shall follow the form of “CHPAFF2k050800”. The list below shows all the proposed Product Model numbers. AFF2k050ADDBUA4AA AFF2k100ADDBUA4AA AFF2k200ADDBUA4AA AFF2k400ADDBUA4AA AFF2k800ADDBUA4AA See “FCC ID” document, included with this submission, for details. 2 Document #: 36-0044 AFF2k050800 Operational Description 06/15/07 05/30/07 3) Installation and Operating Instructions: (c)(3) Instructions for installation and operation are given in the equipment manual , included with this submission. See the document: 453375-108 (submitted in 2 parts). 4) Type of Emission: (c)(4) 6M00W7W COFDM modulation based on Qualcomm’s MediaFLO modulation. This is in the process of being standardized through the Telecommunications Industry Association (TIA). Bandwidth is 6MHz. 5) Frequency Range: (c)(5) 698-746 MHz band. 6MHz Channels 6) Operating Range and Power Variation: (c)(6) 50W – 800W (model dependant) Variation of output power: For a description on how to set the output power of the transmitter, see section 1.6.3 of the User Manual. (This can be found in “Part 1” of the User Manual submitted as part of this filing.) 7) Power Rating: (c)(7) 50W – 800W average power out of the transmitter before antenna with MediaFLO (COFDM) modulation. This application is for a family of transmitters designed to provide power up to 800W. At this time, test data is available for a maximum of 800W, so we are requesting certification for the family of transmitters up to this power level. Power shall be limited to 50kW ERP when antenna gain is taken into account. In all cases, the transmitter installation shall conform to limits set forth in the FCC rules, Part 27. 8) E & I on Final PA Devices: (c)(8) Drain voltage 32V Drain current @6-7A per device @ nominal power (current is a function of driving power) 3 Document #: 36-0044 AFF2k050800 Operational Description 06/15/07 05/30/07 9) Tune-up procedures: (c)(9) AFF2k050800 transmitter tune-up procedures are provided as part of the user manual.

Operational Description

Digital Modulation Characteristics 1 Document #: 25-0024 June 15, 2007 DIGITAL MODULATION CHARACTERISTICS - MediaFLO The digital modulation format is Coded Orthogonal Frequency Division Multiplexing (COFDM) with a QPSK, 16-QAM, or layered constellation with the OFDM symbol rate and occupied bandwidth optimized for a 6 MHz Forward Link Only (FLO) RF channel. FLO Modulation techniques applied in use with this product adhere to the FLO Air Interface Specification, Rev 1.1, which is a FLO TM Forum 1 approved specification that is currently being standardized within the TIA (TR47.1 sub-committee). The Forward Error Correction (FEC) used employs a concatenated approach consisting of an outer Reed-Solomon (RS) code and an inner Parallel Concatenated Convolutional Code (PCCC), or Turbo Code. The outer RS code is intended for use as an erasure correction code, with each RS code block distributed over the duration of 1 second, referred to as a superframe. The RS code can correct erasures caused by impulsive- type interference and time-selective fading, ensuring robust operation over a wide range of mobile speeds from pedestrian (e.g., 3 km/hr) to highway (over 100 km/hr) reception. Each RS code block consist of multiple packets, to each of which is appended a Cyclic Redundancy Checksum (CRC). After addition of the CRC, the packet is Turbo encoded using one of the supported data rates {1/3, ½, 2/3}. The bits in each Turbo encoded packet are interleaved, scrambled and then mapped to modulation symbols from either a QPSK or 16-QAM constellation. FLO also supports the use of layered modulation, which enables the transmission of two component bit streams through the Physical layer with different levels of robustness to reception. The two components are referred to as the base and enhancement components. In the case of layered modulation, a packet each for the base and the enhancement component is independently Turbo encoded, bit interleaved, and scrambled prior to combining the bits in the processed packets to generate modulation symbols from either a 16-QAM or non-uniform 16-QAM constellation. The constellations supported by FLO are depicted in Figures 1 – 3. 1 Further information on the FLO TM Forum can be found at www.floforum.org.
