Valerann Ltd. FCC ID:2AR64A2200 Exposure limit according to §15.247(i) The stud module is classified as a mobile device. The FCC limit for power density for general population/uncontrolled exposure is f/1500 mW/cm2 for 300 – 1500 MHz frequency range: P = 915/1500 = 0.61 mW/cm2 The power density P (mW/cm2) = PT / 4 r2 PT is the transmitted power, which is equal to the peak transmitter output power 21.11 dBm plus maximum antenna gain (-5) dBi, the maximum equivalent isotropically radiated power EIRP is PT = 21.11 dBm - 5 dBi = 16.11 dBm = 41 mW. The power density at 20 cm (minimum safe distance, required for mobile devices), calculated as follows: Compliance with FCC limit: 41 mW / 4 (20 cm) 2 = 0.008 mW/cm2 << 0.61 mW/cm2 General public cannot be exposed to dangerous RF level.
