10 November 2010 Federal Communications Commission Authorization and Evaluation Division Re: Adjustment of the Model CSI-DSP85-25X-S8 In-building Amplifier in the Field The CSI Model DSP85-25X-S8 In-Building Amplifier offers only adjustment of gain (below its factory-set maximum gain level) to the technician during installation and maintenance activities. This adjustment is dependent on the physical environment in which the amplifier is to be installed and is described in the Installation and Users Manual. This is the only adjustment accessible without opening the amplifier. Frequency response and gain thresholds are factory set and in no circumstance are they to be adjusted in the field.

Evaluation of the CSI Model CSI-DSP85-25X-S8 BDA For Compliance with FCC Guidelines For Human Exposure to Radio Frequency Electromagnetic Fields Rev-2 8 December 2010 General The CSI Model CSI-DSP85-25X-S8 Bi-directional amplifier is considered to be a dual- band “mobile” device operating in both the Cellular Service authorized under part 90. As such, the equipment is required to be evaluated for RF exposure if operated below 1.5 GHz with an effective radiated power (ERP) of 1.5 watts or more or if operated above 1.5 GHz with an effective radiated power (ERP) of 3.0 watts or more, as defined in 2.1091 of FCC rules. Downlink For the downlink portion of the Model CSI-DSP85-25X-S8 BDA, the maximum rated output power is +30.0dbm (1000 mW) in the 800 MHz band (<1.5 GHz). As stated in the Model CSI-DSP85-25X-S8 Manual, the maximum authorized indoor antenna gain is 3 dBi, corresponding to a typical Multi-Band Omni-Directional antenna. The Table below shows the results of the calculated ERP, neglecting cable losses. Frequency Power Out Ant Gain EIRP ERP Limit 851-869 MHz 31.1 dBm 3 dBi 34.1 dBm 1,562 mW 1.5 W As shown in the above table, the level exceeds the allowable limit and must be evaluated for minimum separation distances in order to comply with the exposure limits of 1.1310 of the FCC rules. Using the guidelines in FCC OET Bulletin 65 and Supplement C, the power density at a reasonable distance from the maximum gain antenna was calculated. The minimum safe distance was also determined based on the uncontrolled exposure limits defined in Table 1B of FCC rules 1.1311. The following assumptions are made concerning these calculations: SMR Band Po = 1288 mw average Cable Loss = 0 dB Ant Gain = 3 dBi Frequency = 860 MHz Main Beam (worst-case) Rooftop 100% reflection Reasonable Distance = 2 feet (60 cm) Therefore, from OET Bulletin 65, S = (PG)/4πR 2 or S = EIRP/4πR 2 For 100% reflection, a doubling of the field strength can be expected. The above equation can be modified to, S = (2) 2 PG/4πR 2 = EIRP/πR 2 Solving for S at a distance of 2 feet (60 cm) gives, S = (1288) (2)/ π (60) 2 = 0.23 mw/cm 2 From FCC rules 1.1311, Table 1B, the allowable limit for uncontrolled exposure is f(MHz) / 1500. At a frequency of 860 MHz, the limit is 0,57 mw/cm 2 . The calculated values of 0.23 is below both the limit thereby showing compliance under worst-case operating conditions. The Cautions in the Model CSI-DSP85-25X-S8 manual clearly define the antenna selection and installation criteria in order to maintain a minimum 60-centimeter separation. Uplink For the downlink portion of the Model CSI-DSP85-25X-S8 BDA, the maximum rated output power is +30.0dbm (1000 mW) in the 800 MHz Band (<1.5 GHz). As stated in the Model CSI-DSP85-25X-S8 Manual, the maximum authorized outdoor antenna gain is 14 dBi, corresponding to a typical Multi-Element Yagi-Directional antenna. The Table below shows the results of the calculated ERP for this case, neglecting cable losses. Frequency Power Out Ant Gain EIRP ERP Limit 806-824 MHz 31.6 dBm 14 dBi 45.6 dBm 22,071 mW 1.5 W As shown in the above table, the level exceeds the allowable limit and must be evaluated for minimum separation distances in order to comply with the exposure limits of 1.1310 of the FCC rules. Using the guidelines in FCC OET Bulletin 65 and Supplement C, the power density at a reasonable distance from the maximum gain antenna was calculated. The minimum safe distance was also determined based on the uncontrolled exposure limits defined in Table 1B of FCC rules 1.1311. The following assumptions are made concerning these calculations: SMR Band Po = 1445 mw average Cable Loss = 0 dB Ant Gain = 14 dBi Frequency = 815 MHz Main Beam (worst-case) Rooftop 100% reflection Reasonable Distance = 6 feet (183 cm) Therefore, from OET Bulletin 65, S = (PG)/4πR 2 or S = EIRP/4πR 2 For 100% reflection, a doubling of the field strength can be expected. The above equation can be modified to, S = (2) 2 PG/4πR 2 = EIRP/πR 2 Solving for S at a distance of 6 feet (183 cm) gives, S = (1445) (25)/ π (183) 2 = 0.34 mw/cm 2 From FCC rules 1.1311, Table 1B, the allowable limit for uncontrolled exposure is f(MHz) / 1500. At a frequency of 815 MHz, the limit is 0,54 mw/cm 2 . The calculated values of 0.34 is below both the limit thereby showing compliance under worst-case operating conditions. As in the case of the downlink, the Cautions in the Model CSI-DSP85-25X-S8 manual clearly define the antenna selection and installation criteria in order to maintain a conservative 6-foot separation.

Test Report No. R-5408N Retlif Testing Laboratories R CERTIFICATION APPLICATION SUMMARY Applicant/Manufacturer: Cellular Specialties 670 North Commercial Street Manchester, NH 03101 Equipment under Test (EUT): The EUT is a Digital Repeater System operating in the 800 MHz smr band. Model: CSI-DSP85-25X-S8 FCC ID Number: FCC ID: NVRCSI-DSP25XS8 IC ID Number: 4307A-DSP25XS8 Applicable Test Standards: FCC Parts 2 & 90, RSS-131, Issue 2 Measurement Procedure: ANSI/TIA-603-C-2004 RSS-131, Issue 2 Device Classification: Mobile EUT Frequency Range Band: Uplink: 806 MHz to 824 MHz Downlink: 851 MHz to 859 MHz Power Output Rating for Uplink: 1.44W Certification Grant based on Downlink: 1.30W Intermodulation Data Composite Power Modulation Type: TDMA (DXW) RF Exposure + Antenna Installation: See Attached Installation/Users Manual and MPE Evaluation Measurements Required by FCC: See Report Section 1 (Summary of Test Program) - RF Power Output - Occupied Bandwidth - Intermodulation Characteristics - Frequency Stability - Spurious Emissions at Antenna Terminals - Effective Radiated Power of Spurious Radiation Additional Measurements Required by RSS -131: - Mean Output Power - Passband Gain & Bandwidth - Spurious Emissions (two tone) - 99% Bandwidth Test Report No. R-5408N Retlif Testing Laboratories R SECTION 1 SUMMARY OF TEST PROGRAM OCCUPIED BANDWIDTH Measurement Procedure: For Occupied Bandwidth, measurements were made to compare the input signal to the output signal. The signal generator output was connected to the spectrum analyzer. A TDMA modulation signal was then applied to the carrier. Waveforms were then noted on an X-Y plot. Next, the signal generator was connected to the EUT and the output of the EUT was connected to the spectrum analyzer. The output waveform after amplification was then compared to the original input signal to ensure that no significant differences occurred between the input signal and the amplified signal. Testing was performed at three frequencies within each passband (uplink and downlink). See Occupied Bandwidth Data. SPURIOUS EMISSIONS AT ANTENNA TERMINALS Measurement Procedure: The signal generator output was connected in turn to the uplink and downlink input ports of the EUT. The input power level was at the maximum level which was ascertained during the Power Output test. A spectrum analyzer was connected to the output of the EUT. The input test frequencies used were three frequencies (low, mid & high) within each passband (uplink and downlink). The level of any spurious emission was recorded. Testing was performed in the frequency range of 30MHz to 9GHz. Testing was performed for TDMA modulation type. The spurious emissions limit is -13dBm as specified in FCC Part 90. All emissions were below the specified -13dBm limit. See attached test data. EFFECTIVE RADIATED POWER OF SPURIOUS RADIATION Measurement Procedure: The test sample was placed on an 80cm high wooden test stand which was located 3 meters from the test antenna on an FCC listed test site. A signal generator was connected to the input of the amplifier. The signal generator output was set to provide the input power level necessary to achieve maximum output power of the amplifier at 3 frequencies (low, mid & high) within each passband (uplink and downlink). The effective radiated power of each out of band spurious emission was measured using the substitution method specified in ANSI/TIA-603-C-2004. The frequency range of the test was 30MHz – 9GHz. The limit for out of band spurious emissions is -13dBm as specified in Part 90. All emissions were below the specified -13dBm limit. See attached test data. Test Report No. R-5408N Retlif Testing Laboratories R RF POWER OUTPUT (Composite Power) Measurement Procedure: The RF Power Output test was performed using RMS channel power measurements of a single TDMA channel. The measurements were taken with the AGC turned off at maximum output power with all spurious emissions below the -13dBm limit. The measured output power matched the manufacturer’s rated output power. See attached test data. INTERMODULATION CHARACTERISTICS (TWO TONE) Measurement Procedure: Two signals were injected, in turn, to each uplink and downlink frequency band via a two way power combiner. Testing was performed at both the low band edge and high band edge of each pass band. The output of each signal generator was adjusted so that the two output fundamental frequencies were equal in magnitude. Testing was performed for TDMA Modulation type. At the maximum specified input power levels all intermodulation products were at -13dBm or below. See attached test data. FREQUENCY STABILITY MEASUREMENTS Measurement Procedure: The test sample was placed into a temperature chamber with the AC input power supplied…
