This document presents an analysis of Maximum Permissible Exposure (MPE) in accordance with FCC regulations §1.1310 and §2.1091. The primary objective is to ensure that devices operating under these regulations do not expose the public to radio frequency energy levels exceeding the Commission's safety guidelines.
The report details the applicable standards, including limits for general population/uncontrolled exposure across various frequency ranges. It outlines the calculation formula used to predict power density at a specified distance, considering factors such as power input to the antenna, antenna gain, and distance from the radiation source.
Specific calculations are provided for BT and DECT modes, including antenna gain, maximum tune-up power, evaluation distance, power density, and MPE limits. The analysis also addresses simultaneous transmission scenarios, demonstrating compliance with the combined exposure limits. The conclusion states that the device complies with FCC RF exposure guidelines, provided a minimum separation distance of 20cm is maintained from nearby persons.
