RF EXPOSURE CLASSIFICATION Systems operating under the provision of 47 CFR 1.1307(b)(1) shall be operated in a manner that ensures that the public is not exposed to radio frequency energy levels in excess of the FCC guidelines. The Cisco router platform will only be used with a separation of 20 centimeters or greater between the antennas and the body of the user or nearby persons and can therefore be considered a mobile transmitter per 47 CFR 2.1091(b).

EQUATIONS The equations used are based on methods described in OET Bulletin 65 and appendices. Given E = √ (30 * P * G) / d and S = E ^ 2 / 3770 where E = Field Strength in Volts/meter P = Power in Watts G = Numeric antenna gain d = Distance in meters S = Power Density in milliwatts/square centimeter Combining equations and rearranging the terms to express the distance as a function of the remaining variables yields: d = √ ((30 * P * G) / (3770 * S)) Changing to units of Power to mW and Distance to cm, using: P (mW) = P (W) / 1000 and d (cm) =100 * d (m) yields d = 100 * √ ((30 * (P / 1000) * G) / (3770 * S)) d = 0.282 * √ (P * G / S) where d = distance in cm P = Power in mW G = Numeric antenna gain S = Power Density in mW/cm^2 Substituting the logarithmic form of power and gain using: P (mW) = 10 ^ (P (dBm) / 10) and G (numeric) = 10 ^ (G (dBi) / 10) yields d = 0.282 * 10 ^ ((P + G) / 20) / √ S where d = MPE distance in cm P = Power in dBm G = Antenna Gain in dBi S = Power Density Limit in mW/cm^2 Rearranging terms to calculate the power density at a specific distance yields S = 0.0795 * 10 ^ ((P + G) / 10) / (d^2) Page 7 of 11 COMPLIANCE CERTIFICATION SERVICES DOCUMENT NO: CCSUP4031A 561F MONTEREY ROAD, MORGAN HILL, CA 95037 USA TEL: (408) 463-0885 FAX: (408) 463-0888 This report shall not be reproduced except in full, without the written approval of CCS.

MPE LIMITS §1.1310 The criteria listed in Table 1 shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation as specified in §1.1307(b), except in the case of portable devices which shall be evaluated according to the provisions of §2.1093 of this chapter. 8.2. CO-LOCATED MPE LIMITS Per OET Bulletin 65, for frequency bands with the same MPE limits, the Power Densities produced by each transmitter are summed. The summation must be under the limit for the band. Per OET Bulletin 65, for frequency bands with different limits the Power Densities are calculated separately for each band, divided by the limit for the band and the results are then summed. The summation must be less than 1.

CONTRIBUTION OF EACH TRANSMITTER For the Part 22 Transmitter, 824 MHz is used for the calculation. For the Part 24 Transmitter, 1850 MHz is used for the calculation. For the 2.4 GHz band Transmitter, 2412 MHz is used for the calculation, both the highest power level and the highest antenna gain are used for the calculation. For the 5 GHz band Transmitter, 5180 MHz is used for the calculation.
