Greg VaughtMay 8, 2001 Motorola Inc Confidential FCC Cover Letter Re. Comments on Test Report Exhibit: We realize this device is a new version of a previously certified transmitter. Since the RF section was not changed we are accepting the RF conducted data from the previous submittal, along with your new data for the radiated tests. The Test Report Exhibit and data were accepted based on the following: 1. Radiated Measurements: FCC has recently stressed that the “substitution method”, detailed in TIA- 603, be used to measure radiated emissions from licensed transmitters. We will accept your data, which is based on a calculated power level rather than the substitution method, since FCC had accepted similar data in your previous submittals. We are confident that this device is compliant since the emission levels are well below the required limit. Please use the substitution method in the future. Also, please note that the FCC limits are based on the power level radiated from a dipole antenna and not isotropic. In the future, please indicate the measurement bandwidths used for all measurements. 2. Spurious a nd Har mo nic E missions Co nd ucted Measure me nts: These meas ure me nts s ho uld have been performed using a 30 kHz bandwidth instead of a 30 Hz bandwidth. Again we are accepting this data since the FCC had accepted it in your previous submitted (1999). In order to compare your data to the FCC Limits, we applied a BW correction factor of 30 dB (10log (30kHz/30Hz) to the data. With this correction, your emission levels remained below the –13dBm limit. Please use the proper BW in future submittals. 3. Occupied BW: In the future, please apply the proper emission mask to the plots to simplify evaluating the data. We evaluated the data against the TIA IS-97 mask. We welcome any questions or comments. Please froward your question to me. Sincerely, Raymond Klouda Senior Engi neer Elite Electronic Engineering Inc. cc. FCC

FCC Filing: -48V SC4812T @ 800 MHz CDMA BTS 1 DESCRIPTIVE INFORMATION FCC FILING FOR -48V SC4812T @ 800 MHz CDMA BTS The Information in this exhibit is in accordance with the FCC Rules and Regulations, Vol. II, Part 2, Subpart J. Sections 2.983 through 2.999 are addressed. Section 2.983 (a)Name of Applicant and Manufacturer: MOTOROLA Section 2.983 (b) Identification of Equipment: IHET5AW1 Section 2.983 (c) Quantity Production: Quantity Production is Planned. Section 2.983 (d) Technical Description This Transmitter is intended for use in the Public Cellular Radio Telecommunications Service and is designed in compliance with the FCC Rules and Regulations Title 47, Part 22(H).This transmitter is capable of spread spectrum (CDMA) operation, and allows up to 64 Walsh codes to support Pilot, Sync, Paging and Traffic channels. (1) Types of Emissions This equipment will be capable of operation using wide band spread spectrum techniques employing Direct Sequence Code Division Multiple Access (DS-CDMA) digital communication techniques. For this transmitter, the emission designator is 1M25F9W (per FCC Part 2.201, subpart C). (2)Frequency Range This transmitter operates within the 869.70 to 893.31 MHz Band (per FCC Part 22). This base station will support CDMA operations on channel numbers 1013 through 1023 and 1 through 777 inclusive. (3) Range of Operating Power The rated maximum average power out of the -48V SC4812T @ 800 MHz CDMA BTS is 44 W (46.5 dBm). However, in CDMA the actual power output is based on the number of traffic channels in operation. The minimum power occurs when only a pilot signal is present. The maximum power occurs when a pilot along with synchronization, paging, and traffic channels are present. For a typical system setup, the theoretical difference between minimum power and maximum power is 8dB. The output power is variable in 0.25 dB steps. The range is 12 dB. FCC Filing: -48V SC4812T @ 800 MHz CDMA BTS (3) Range of Operating Power (cont.) In addition, the dynamics of a CDMA system allow for what is called “cell breathing”. This allows an operator to vary the range of a cell by controlling the power of the pilot signal. (4) Maximum Power Limits The peak output power of a base station transmitter may not exceed 500 Watts as defined in Part 22.913 (a) (5)Applied voltages and currents into the final transistor elements of the transmitter output: In the CDMA system, the applied voltages and currents into the final transistor elements SRF7042X4 for 44 W output: Drain 27.7 VDC Drain Current 2.0 AMPS x 3 Gate Voltage 4 VDC (6) Function of Each Active Device Refer to the Operational Description Exhibit. (7) Complete Circuit Diagrams Refer to the Schematics Exhibit. (8) Instruction/Installation Manual Refer to the Installation Manual Exhibit. (9) Tune-Up/Optimization Procedure Refer to the Users Manual Exhibit. FCC Filing: -48V SC4812T @ 800 MHz CDMA BTS (10) Means for Frequency Stabilization Refer to Section F of the Test Report Exhibit. The Clock Synchronization Module (CSM/CSM2) provides clock and time signals for an SC4812T @ 800 MHz CDMA BTS. In addition, it provides the primary source, a 3 MHz clock, for the transmit synthesizer in the Broadband Transceiver. The CSM/CSM2 relies on a GPS receiver, either riding piggyback onto the CSM/CSM2 card or remotely located in an integrated package with the GPS antenna as the primary time reference for the ovenized oscillator. Two types of redundancy are provided: 1) Dual CSM/CSM2 cards provide redundancy in case of primary CSM/CSM2 failure. 2) Redundancy is also provided by either a High Stability Oscillator (HSO) or a Low Frequency Reference (LFR), such as a Loran C receiver, residing in a separate slot. The HSO is provided in case of GPS system failure. The CSM/CSM2 uses the received signals as a reference to provide the required clock for the site. The CSM/CSM2 distributes CDMA time, a 19.6608 MHz clock, and a two second synchronization pulse every even second of universal time to the CDMA Clock Distribution (CCD) Cards . The CSM/CSM2 is also responsible for configuration and management of the GPS and LFR systems. CSM/CSM2 software determines on a site basis what the GPS and LFR configurations should be. For future Commercial CDMA systems, GPS and LFR configuration information could optionally be downloaded to the CSM/CSM2 from the GLI2. The CSM/CSM2 is managed by the GLI2. The High Stability Oscillator (HSO) or Low Frequency Time Reference (LFR) is used to provide a stable time reference in case of a GPS system failure or shutdown. The output of the LFR card is routed to the CSM/CSM2 cards, which derive the appropriate time references for the BTS. The current LFR is a LoranC receiver. In areas where LoranC is unavailable, the HSO may be used. FCC Filing: -48V SC4812T @ 800 MHz CDMA BTS (11) Means for Attenuation of Spurious Emissions Refer to Section C of the Test Report Exhibit. Bandpass filters are employed in the transmit RF circuit to attenuate far out spurious emissions. The filter used here is of an air dielectric cavity resonator type. The baseband employs a discrete L-C 7-pole elliptic filter. This filter is used to attenuate sideband noise and close in spurious emissions. In addition, suppression of spurious radiation is obtained by proper shielding techniques. Means for Limiting Modulation Refer to Sections B and F of the Test Report Exhibit. In a CDMA system, the input signal (voice for example) is sampled and coded in a vocoder. This signal is then spread to 1.23 MHz by a pseudo-random spreading code. This spreading code sets the bandwidth of the spread-spectrum signal. If more than one signal is in operation (i.e. more than one voice channel), then the two signals are simply layered one atop the other within the 1.23 MHz band. So, to some extent, the bandwidth of the transmitted signal is limited by the chip rate of the PN spreading code. Primary limiting of the CDMA signal bandwidth is accomplished by the use of a prog…

FCC Filing: -48 V SC4812T @ 800 MHz CDMA BTS BTS Tune-up Procedure/Bay Level Offset Calibration Overview: The BTS Tune-up procedure, also known as the Bay Level Offset Calibration, is to be performed upon installation of the BTS, once a year after installation, and whenever certain components in the TX path are replaced. Reference: Pages 3-59 and 3-60 of the “SC4812T CDMA BTS Optimization/ATP” manual gives a more detailed description of the Bay Level Offset Calibration Procedure and when it should be performed. Required Test Equipment and Software: The Bay Level Offset Calibration Procedure requires using a computer which has LMF (Local Maintenance Facility) software, developed by Motorola in order to communicate with the BTS. Additionally, an RS-232 / GPIB interface box is required so that the computer may control the test equipment. The test equipment needed is a communication test set, which can only be from certain vendors defined by Motorola. There is additional cabling, couplers, and attenuators that are required. Reference: Pages 3-39 through 3-58 of the “SC4812T CDMA BTS Optimization/ATP” manual give a detailed description of the required test equipment, cabling, couplers, and attenuators, as well as how to calibrate the entire test system. Description of Procedure: The Bay Level Offset Calibration can be performed at whichever CDMA channels are to be used at the particular cell site, at the desired output power for that cell site. Using the test equipment and LMF terminal, a calibration program, developed by Motorola, determines the required output power from the BBX2 modules in order to get the desired output power at the TX antenna terminal. The calibration program will thus determine the proper Bay Level Offset, which is basically the difference between the BBX2 and TX antenna output powers, for each CDMA channel. These Bay Level Offsets are subsequently downloaded from the LMF terminal to the BBX2 modules, thus guaranteeing that the proper output power is being obtained at each TX antenna. Reference: Pages 3-60 through 3-66 of the “SC4812T CDMA BTS Optimization/ATP” manual give the details for the Bay Level Offset Calibration procedure. Audit Procedure: The Bay Level Offset Calibration can be audited whenever chosen by the customer. Motorola supplies the customer with an audit procedure, which is a software program developed by Motorola, that can be performed at the customer’s discretion to verify proper output power is being obtained.
