This document presents the radio frequency (RF) exposure assessment for a portable device with FCC ID 2BBGN-100D. The evaluation is conducted by Shenzhen CTB Testing Co., Ltd. to ensure compliance with the Federal Communications Commission (FCC) guidelines, specifically §15.247(e)(i) and §1.1307(b)(1), which mandate that devices operate in a manner that does not expose the public to excessive RF energy levels.
The assessment adheres to KDB447498 D01 General RF Exposure Guidance V06, focusing on the 1-g SAR and 10-g SAR test exclusion thresholds for devices operating between 100 MHz and 6 GHz at test separation distances of ≤ 50 mm. The document details the calculation methodology, which involves considering the maximum power of the channel, including tune-up tolerance, and the minimum test separation distance. The formula used is [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)]·[√f(GHZ)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR.
The results of the SAR test exclusion calculations for various 2.4GWIFI modulation schemes are presented, demonstrating that the calculated values are below the FCC limit of 3.0 for 1g SAR. Therefore, the device meets the RF exposure requirements for portable use.
