This report assesses the Maximum Permissible Exposure (MPE) of a device to ensure compliance with FCC regulations §1.1310 and §2.1091. The document outlines the applicable standards, which mandate that devices operate in a manner that does not expose the public to radio frequency energy levels exceeding the Commission's guidelines.
The report provides limits for Maximum Permissible Exposure for general population/uncontrolled exposure across various frequency ranges, specifying electric field strength, magnetic field strength, power density, and averaging time. It includes a calculated formulary for predicting MPE limits at a given distance, considering factors such as power input to the antenna, antenna gain, and distance from the radiation source.
Calculated data is presented for different modes of operation, including LoRa, 2.4G Wi-Fi, 5G Wi-Fi, BLE, and Classic BT, detailing antenna gain, tune-up output power, evaluation distance, power density, MPE limit, and MPE ratio. The analysis concludes that the device meets FCC MPE requirements at a 20 cm distance, with simultaneous transmission considerations taken into account.
