This document presents the Maximum Permissible Exposure (MPE) assessment for a Bluetooth device with FCC ID: 2AYOQ-X4BT. The evaluation adheres to FCC guidelines outlined in 1.1310 and KDB447498 D01, ensuring that human exposure to radio frequency (RF) radiation remains within safe limits. The report details the limits for both occupational/controlled and general population/uncontrolled exposure scenarios, considering frequency ranges and corresponding electric field strength, magnetic field strength, and power density.
The MPE calculation method is described, including formulas for electric field strength and power density, taking into account the average RF output power, antenna gain, and separation distance. The document also includes measurement results for various Bluetooth channels (2402MHz~2480MHz), presenting conducted power, tune-up power, antenna gain, and calculated power density. The results demonstrate compliance with the power density limit of 1mW/cm². The report concludes with the signature and contact information of the responsible party.
