ATTACHMENT FCC ID: PBN-EX18100 ** MPE Calculations ** The MPE calculation for this exposure is shown below. The peak radiated output power (EIRP) is calculated as follows: EIRP = P + G EIRP = 10.41 dBm + 3.423dBi EIRP = 13.833 dBm Where, P = Power input to the antenna (mW) G = Power gain of the antenna (dBi) Power density at the specific separation: S = PG/(4R 2 π) S = (10.99 * 2.2) / (4 * 20 2 * π) S = 0.0048 mW/cm 2 Where, S = Maximum power density (mW/cm 2 ) P = Power input to the antenna (mW) G = Numeric power gain of the antenna R = Distance to the center of the radiation of the antenna (20cm = limit for MPE) The Maximum permissible exposure (MPE) for the general population is 1 mW/cm 2 . The power density at 20cm does not exceed the 1 mW/cm 2 limit. Therefore, the exposure condition is compliant with FCC rules. Estimated safe separation: R = √(PG / 4π) R = √(10.99 * 2.2 / 4π) R = 1.39 Cm Where, P = Power input to the antenna (mW) G = Numeric power gain of the antenna R = Distance to the center of the radiation of the antenna (20cm = limit for MPE) The numeric gain(G) of the antenna with a gain specified in dB is determined by: G = Log -1 (dB antenna gain / 10) G = Log-1 (3.423 / 10) G = 2.2

Page 6 of 24 3.2 Transmitter requirements 3.2.1 Carrier Frequency Separation Procedure: The carrier frequency separation was measured with a spectrum analyzer connected to the antenna terminal, while EUT had its hopping function enabled. After the trace being stable, the reading value between the peaks of the adjacent channels using the marker-delta function was recorded as the measurement results. The spectrum analyzer is set to: Span = 15 MHz (wide enough to capture the peaks of two adjacent channels) RBW = 30 kHz (1% of the span or more) S…
