FCC ID: 2A3MU-C5 Prediction of MPE at a given distance According to 447498 D04 Interim General RF Exposure Guidance v01 The MPE-based test exemption condition is in terms of ERP, defined as the product of the maximum antenna gain and the delivered maximum time-averaged power. For this case, a RF source is an RF exempt device if its ERP (watts) is no more than a frequency-dependent value, as detailed tabular form as below. These limits have been derived based on the basic specifications on Maximum Permissible Exposure (MPE) considered for the FCC rules in § 1.1310(e)(1). “f” is in MHz Simultaneous Transmission with MPE-based Exemptions For these cases, a device with multiple RF sources transmitting simultaneously will be considered an RF exempt device if the condition of following Formula is satisfied. As this equipment: Distance=60cm BLE:f1 = 2440, WIFI:f2 = 2437, UHF:f3= 469.95 So P th1 = P th2 =6912.0mW, P th3 = 2165.5mW Where: EIRP = Pm + Gi Pt=10 (EIRP/10) =10 (EIRP-2.15/10) Pm = measured transmitter output power in dBm, Pt = transmitter output power in milliwatts, Gi = numeric gain of the transmitting antenna (unit-dBi) FCC ID: 2A3MU-C5 Ant gain Gi1=1.56 dBi, Gi2=1.56 dBi, Gi3=4 dBi Pm1=4.09 dBm, Pm2=21.58 dBm, Pm3=29.883 dBm So BLE: Pt1=10 (5.65/10) mW =3.673 mW<6912.0mW WIFI: Pt2=10 (23.14/10) mW =206.063 mW<6912.0mW UHF: Pt3=10 (33.883-2.15/10) mW =1490.390 mW<2165.5mW Σ= Pt1/P th1 + Pt2/ P th2 + Pt3/ P th3 =0.72<1 The MPE-based test exemption condition is meets the requirements.
