Rev 009C REVISED DOCUMENT 2/1/2007 4 Product Description Cellular Specialties, Inc. (CSI) developed the Wireless Engine Digital Repeater for use within enclosed structures where sufficient signal from local cell sites to operate cell phones is unavailable. Adequate signal must be available outside the structure as a prerequisite to achieving in-building coverage. The Digital Repeater is connected to an external antenna, usually on the roof, and to one or more internal antennas placed strategically throughout the area where wireless services are desired. The external antenna typically is a directional type such as a “yagi”. Internal antennas are typically omni-directional, although various other types may be used depending on the coverage application. The Frequency Agile Repeater (FAR) amplifies both the “Uplink” (phone to tower) & “Downlink”(tower to phone) signals thus facilitating communications to and from the intended wireless infrastructure. There are seven amplification stages on either the downlink or the uplink creating a total of +85 dB nominal gain on each link. Ga…

MODEL DSP85-1W-S Frequency Programmable Repeater FCC ID LABEL FCC ID NVRCSI-DSP85-1W-S IC: 4307A-DSP85-1W-S This device complies with parts 90 and 2 of the FCC rules and with Industry Canada specification RSS-131

December 7, 2006 Mr. Scott Wentworth Retlif Laboratories 101 New Boston Rd. Goffstown, NH 03045 Re: Adjustment of the Model DSP85-1W-S In-building Amplifier in the Field The CSI Model DSP85-1W-S 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.

MPE Compliance-DSP85-S-Rev-2-yagi.doc 1 Evaluation of the CSI Model DSP85-1W-S Frequency Programmable Repeater For Compliance with FCC Guidelines For Human Exposure to Radio Frequency Electromagnetic Fields 7 December 2006 MPE Compliance-DSP85-S-Rev-2-yagi.doc 2 General The CSI Model DSP85-1W-S Repeater is considered to be a “mobile” device operating in 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, as defined in 2.1091 of FCC rules. Downlink For the downlink portion of the Model DSP85-1W-S, the maximum rated output power is +30dBm (1000 mW). As stated in the Model DSP85-1W-S Manual, the maximum authorized antenna gain is 3 dBi, corresponding to an Omni-Directional antenna. Neglecting cable losses, the worst-case EIRP will be 2.0 watts or an ERP of 1.22 watts, (ERP=EIRP/1.64). This is well below the 3.0 watts ERP limit and therefore excludes the downlink from routine evaluation. The Cautions in the Model DSP85-1W-S manual clearly define the antenna selection and installation criteria in order to maintain a minimum 20-centimeter separation. Uplink For the uplink portion of the Model DSP85-1W-S, the maximum rated output power is +30dBm (1000 mW). As stated in the Model DSP85-1W-S Manual, the maximum authorized antenna gain is 14 dBi, corresponding to a Multi Element Yagi-Directional or Corner Reflector antenna. Neglecting cable losses, the worst-case EIRP will be 25.1 watts or an ERP of 15.3 watts. Under these conditions the unit 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: Po = 1000 mw average Cable Loss = 0 dB Ant Gain = 11.8 dBd (14 dBi) Frequency = 806-824 MHz Main Beam (worst-case) Rooftop 100% reflection Reasonable Distance = 4 feet (120 cm) MPE Compliance-DSP85-S-Rev-2-yagi.doc 3 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 4 feet (120 cm) gives, S = (1000) (25)/ π (120) 2 = 0.55 mw/cm 2 From FCC rules 1.1311, Table 1B, the allowable limit for uncontrolled exposure is f(MHz)/1500 mw/cm 2 in the frequency range of 300 to 1500 MHz. At 815 MHz this corresponds to 0.55 mw/cm 2 . The calculated value of 0.55 is equal to the limit of 0.55 thereby showing compliance under worst-case operating conditions. As in the case of the downlink, the Cautions in the Model DSP85-1W-S manual clearly define the antenna selection and installation criteria in order to maintain a minimum 4- foot separation.

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 for each modulation. See attached test data. 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 one frequency within each passband (uplink and downlink). See Occupied Bandwidth Data. An explanation of the data is as follows: There are two signals superimposed on each plot, one signal is the waveform before modulation, the other is the modulated carrier. In each case the center of the grid shows a narrowband signal projecting out from the center of the modulation envelope. This signal is actually the stored unmodulated signal. Test Report No. R-4733N-1 FCC ID: NVRCSI-DSP85-1W-S 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 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 types. 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 a 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 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 TIA/EIA-603. 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. RF POWER OUTPUT A signal generator was connected in turn to the uplink and downlink input ports of the test sample. The signal generator was set to maximum input rating and the amplifier was operating at maximum gain. The maximum single channel output power for both the uplink and downlink was measured with a spectrum analyzer connected to the output port. The measured output power was 0.724W for the uplink and 0.871W for the downlink which matched the manufacturer’s rated output power. See attached test data. Test Report No. R-4733N-1 FCC ID: NVRCSI-DSP85-1W-S FREQUENCY STABILITY MEASUREMENTS The test sample was placed into a temperature chamber with AC input power supplied through a variable power source. A signal generator was used to provide the input signal and the output was measured with a frequency counter. With the test sample operating at maximum output power the test sample’s output frequency was measured and recorded at the extremes of the temperature range and at 10 degree increments from -30 degrees C to +50 degrees C while the AC input voltage was varied from 85 to 115% of nominal. The output frequency for both the uplink and the downlink stayed within the assigned frequency band. See attached test data.
