MODEL CSI-DSP95-255-U7C Repeater FCC ID LABEL FCC ID: NVRCSIDSP95255U7C This device complies with parts 27 and 2 of the FCC rules

Evaluation of the CSI Model CSI-DSP95-255-U7C BDA For Compliance with FCC Guidelines For Human Exposure to Radio Frequency Electromagnetic Fields 27 March 2011 General The CSI Model CSI-DSP95-255-U7C Bi-directional amplifier is considered to be a dual- band “mobile” device operating in both the Cellular Service authorized under part 27. 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-DSP95-255-U7C BDA, the maximum rated output power is +38.1dbm (6457 mW) in the 700 MHz band (<1.5 GHz). As stated in the Model CSI-DSP95-255-U7C 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 746-757 MHz 38.1dBm 3 dBi 41.1dBm 7,852 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: 700 MHz Band Po = 6457 mw average Cable Loss = 0 dB Ant Gain = 3 dBi Frequency = 751 MHz Main Beam (worst-case) 100% reflection Reasonable Distance = 4 feet (122 cm) Therefore, from OET Bulletin 65, S = (PG)/4R 2 or S = EIRP/4R 2 For 100% reflection, a doubling of the field strength can be expected. The above equation can be modified to, S = (2) 2 PG/4R 2 = EIRP/R 2 Solving for S at a distance of 4 feet (122 cm) gives, S = (6457) (2)/  (122) 2 = 0.28 mw/cm 2 From FCC rules 1.1311, Table 1B, the allowable limit for uncontrolled exposure is f(MHz) / 1500. At a frequency of 751 MHz, the limit is 0.50 mw/cm 2 . The calculated value of 0.28 is below the limit thereby showing compliance under worst- case operating conditions. The Cautions in the Model CSI-DSP95-255-U7C manual clearly define the antenna selection and installation criteria in order to maintain a minimum 4 feet (122 cm) separation. Uplink For the uplink portion of the Model CSI-DSP95-255-U7C BDA, the maximum rated output power is +29.25dbm (841 mW) in the 700 MHz Band (<1.5 GHz). As stated in the Model CSI-DSP95-255-U7C 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 779-787 MHz 29.25 dBm 14 dBi 43.25 dBm 12882 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: 700 MHz Band Po = 841 mw average Cable Loss = 0 dB Ant Gain = 14 dBi Frequency = 781 MHz Main Beam (worst-case) Rooftop 100% reflection Reasonable Distance = 6 feet (183 cm) Therefore, from OET Bulletin 65, S = (PG)/4R 2 or S = EIRP/4R 2 For 100% reflection, a doubling of the field strength can be expected. The above equation can be modified to, S = (2) 2 PG/4R 2 = EIRP/R 2 Solving for S at a distance of 6 feet (183 cm) gives, S = (841) (25)/  (183) 2 = 0.2 mw/cm 2 From FCC rules 1.1311, Table 1B, the allowable limit for uncontrolled exposure is f(MHz) / 1500. At a frequency of 781 MHz, the limit is 0.52 mw/cm 2 . The calculated value of 0.2 is below both the limit thereby showing compliance under worst-case operating conditions. The Cautions in the Model CSI-DSP95-255-U7C manual clearly define the antenna selection and installation criteria in order to maintain a conservative 6 feet (183 cm) separation.
