FCC Filing- SC4812ET 1X/EVDO @ 800 MHz CDMA BTS 1 of 12 DESCRIPTIVE INFORMATION FCC FILING FOR SC4812ET 1X/EVDO @ 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 2.1033 through 2.1055 are addressed. Section 2.1033 (a) Name of Applicant and Manufacturer: MOTOROLA Section 2. 1033 (b) Identification of Equipment: IHET5EG1 Section 2. 1033 (c) Quantity Production: Quantity Production is planned. Section 2. 1033 (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 128 Walsh codes to support Pilot, Sync, Paging, Supplemental, 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 1M30F9W (per FCC Part 2.201, subpart C). (2) Frequency Range This transmitter operates within the 869.70 to 893.31 MHz Band for 1X/EVDO operation (per FCC Part 22). This base station will support CDMA operations on channel numbers 1013 through 1023 and 1 through 777 inclusive for 1X operation. The base station will support CDMA operations on channel 1020 through 1023 and 1 through 770 inclusive for EVDO operation (3) Range of Operating Power The rated maximum average power out of the SC4812T Lite 1X @ 800 MHz CDMA BTS is 90 W (49.77 dBm) per RF carrier. 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. (3) Range of Operating Power (cont.) FCC Filing- SC4812ET 1X/EVDO @ 800 MHz CDMA BTS 2 of 12 For a typical system setup, the theoretical difference between minimum power and maximum power is about 8 dB. The output power is variable in 0.25 dB steps. 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: The applied voltages and currents into each of the Linear Power Amplifier’s final transistor elements are as follows: Drain 27.0 VDC Drain Current 1.0 AMPS 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- SC4812ET 1X/EVDO @ 800 MHz CDMA BTS 3 of 12 (10) Means for Frequency Stabilization Refer to the Test Report Exhibit. The Clock Synchronization Module (CSM2) provides clock and time signals for an SC4812ET 1X/EVDO @ 800 MHz CDMA BTS. In addition, it provides the primary, source a 3 MHz clock, for the transmit synthesizer in the Broadband Transceiver. The CSM2 relies on a GPS receiver, either riding piggyback onto the 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 CSM2 cards provide redundancy in case of primary 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 CSM2 uses the received signals as a reference to provide the required clock for the site. The 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 CSM2 is also responsible for configuration and management of the GPS and LFR systems. 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 CSM2 from the GLI2. The 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 CSM2 cards, which derive the appropriate time references for the RF section. The current LFR is a LoranC receiver. In areas where LoranC is unavailable, the HSO may be used. FCC Filing- SC4812ET 1X/EVDO @ 800 MHz CDMA BTS 4 of 12 (11) Means for Attenuation of Spurious Emissions Refer to the Test Report Exhibit. Band pass 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. In addition to the digital filters described below, the baseband also employs a discrete anti-alias filter that attenuates signals greater than 2MHz. Out of band emissions are also attenuated by ceramic filters in the transmit RF lineup. In addition, suppression of spurious radiation is obtained by proper shielding techniques. Means for Limiting Modulation Refer to 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 approximately 1.25 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…
