U2ZBT3101 MPE calculation Dear Reviewer, The maximum measured power output is: 7.6dBm The maximum antenna gain for integral antenna is: 1.9dBi The maximum permissible exposure is defined in 47 CFR 1.1310 with 1 mW/cm². The Transmitter is using integral antennas that operate at 20 cm or more from nearby persons. The maximum permitted level is calculated using the general equation: S = P’ / 4πR² P’ = 7.6dBm+1.9dBi =9.5dBm=8.9mW R = 20cm π = 3.1416 Solving for S, the power density at 20 cm is: 0.018mW/cm²
