1 DESCRIPTIVE INFORMATION FCC FILING FOR MICROBTS TYPE B SYSTEM The information in this exhibits 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(d) Technical Description of the equipment. Section 2.983(d)(1) Type or types of emission The emission designator is 1M25G7W(per FCC Part 2.201, Subpart C). Section 2.983(d)(2) Frequency Range This transmitter operates within the 1930 to 1990 MHz Band(per FCC Part 24). This Base Station will support CDMA operations on channel numbers 25 through 1175 as defined ANSI J-STD- 008(1931.25MHz – 1988.75MHz). Section 2.983(d)(3) Range of Operating Power Levels The rated maximum average power out of the Front End Filter is 10Watt(40dBm). However, in PCS 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. Section 2.983(d)(4) Maximum Output Power Rating The maximum output power is 10 Watts(40dBm) Section 2.983(d)(5) Final RF Amplifying Device Power Consumption The power consumption of the Powerwave High Power Amplifier is 162Watt( 27volts , 6 amps) Section 2.983(d)(6) Function of Each Active Device Refer to Exhibit #XX Section 2.983(d)(7) Complete Circuit Diagrams Refer to Exhibit #XX Section 2.983(d)(8) Instruction/Installation Manual Refer to Exhibit #XX 2 Section 2.983(d)(9) Tune-up Procedure All frequency adjustments are set by X-terminal. Refer to Exhibit #XX Section 2.983(d)(10) Circuit Description for Frequency Determining and Stabilizing. GPS(Global Positioning Systems) Receiver in BTS System provides highly accurate Frequency output signal(10MHz), synchronized to UTC(Coordinated Universal Time) signals transmitted by the GPS satellites. This GPS is optimized for synchronization of wireless base stations. Frequency output signal are subjected temperature conditions of 0 to 50 °C. The stability of 10 MHz output is not more than 5 x 10 -11 . Section 2.983(d)(11) Circuit Description for suppression of spurious radiation The transmi front end filter provides filtering of the RF signal in order to meet FCC Specifications. Fot Radiated spurious suppression proper design techniques ans the use of proper shielding techniques reduced the emission levels well below the permissible FCC limits. Section 2.983(d)(12) Description of Modulation Limiting Circuits and Modulation Characteristics 1)Baseband Filtering(FIR Filter) for Modulation Limiting Following the spreading operation, the I and Q impulses are applied to the inputs of the I and Q baseband filters . The baseband filters shall have a frequency response S(f) that satisfies the limits given in Figure 1. Specifically, the normalized frequency response of the filter shall be contained within ±δ 1 in the passband 0  f  f p and shall be less than or equal to -δ 2 in the stopband f  f s . The numerical values for the parameters are δ 1 = 1.5 dB, δ 2 = 40 dB, f p = 590 kHz, and f s = 740 kHz. 3 Figure 1. a Baseband Filters Frequency Response 2) Phase Response Characteristic of FIR Filter π −π 20kHz Frequency Phase 0 -2.5 Figure 1.b Baseband Filters Phase Response 3) After baseband filtering , the binary data (‘0’s and ‘1’s), I and Q mapped into phase according to Table 1. The resulting signal constellation and phase transition are shown in Figure 2. 4 Table 1. Forward CDMA Channel I and Q Mapping IQPhase 00c/4 103π/4 11-3π/4 01-π/4 Figure 2 Forward CDMA Channel Signal Constellation and Phase Transition 5 Section 2.983(e) Standard Test Conditions The following conditions and procedures were followed during testing of this transmitter: Room temperature : +25 o C Room Humidity : 50% AC Supply Voltage : +208VAC(Nominal) Prior to testing, the unit was tuned up according the tune up procedure(Exhibit #xx). All data presented represents the worst case parameter being measured. All test data required by section 2.985 through 2.997 can be found in Exhibits #xx through #XX.

The site address is 6660-B Dobbin Road, Columbia, MD 21045. The test site is one of the highest points in the Columbia area with an elevation of 390 feet above mean sea level. The site coordinates are 39° 11'15" N latitude and 76° 49'38" W longitude. The facility is 1.5 miles North of the FCC laboratory, and the ambient signal and ambient signal strength are approximately equal to those of the FCC laboratory. There are no FM or TV transmitters within 15 miles of the site. The detailed description of the measurement facility was found to be in compliance with the requirements of § 2.948 according to ANSI C63.4 on October 19, 1992. PCTEST Lab is recognized under the National Voluntary Laboratory Accreditation Program for satisfactory compliance with criteria established in Title 15, Part 285 Code of Federal Regulations. These criteria encompass the requirements of ISO/IEC Guide 25 and the relevant requirements of ISO 9002 (ANSI/ASQC Q92-1987) as suppliers of calibration or test results. The Scope of PCTEST Accreditation are for Electromagnetic Compatibility and Telecommunications and FCC. 1.2 PCTEST Location The map at right shows the location of the PCTEST Lab, its proximity to the FCC Lab, the Columbia vicinity area, the Baltimore- Washington International (BWI) airport, and the city of Baltimore, and the Washington, D.C. area.
