This document presents an RF Exposure Evaluation for the HHX001A device, adhering to FCC guidelines outlined in section 1.1307(b). The evaluation focuses on determining whether the device's radio frequency radiation levels comply with established limits for Maximum Permissible Exposure (MPE).
The report details the limits for both Occupational/Controlled and General Population/Uncontrolled exposure scenarios, specifying electric field strength, magnetic field strength, power density, and averaging times. The Friis transmission formula is used to calculate power density at a given distance from the antenna, considering output power and antenna gain.
The test procedure involves utilizing software to enable the EUT (Equipment Under Test) to transmit and receive data across various channels. The evaluation includes specific data for BLE mode, presenting output power, tune-up power, and calculated power density at a distance of 20cm. The results demonstrate compliance with the MPE limit, ensuring the device's safe operation.
