This document presents the RF exposure evaluation for the HTC Wireless Headphones 7, model HTC HP07, bearing the FCC ID 2BHJR-HP07. The evaluation is conducted to ensure that the device complies with the radio frequency exposure limits set by regulatory bodies. The device operates in the 2402-2480MHz frequency range using BT 5.4 BDR+EDR technology, employing GFSK, Π/4-DQPSK, and 8DPSK modulation schemes across 79 channels.
The antenna is a PCB antenna with a gain of -0.58 dBi. The device is powered by a DC 5V 400mA input and a Li-ion battery with a rated voltage of 3.7V and a capacity of 400mAh. The hardware and software versions are V1. The evaluation considers the maximum output power, tune-up tolerance, and separation distance to determine SAR test exclusion thresholds. The calculations demonstrate compliance with the specified limits, indicating that no simultaneous SAR measurement is required.
