This document presents an RF exposure evaluation for a wireless device with FCC ID 2BB3B-TWSY96. The evaluation is conducted according to §15.247(i), §1.1307 (b), and KDB447498, ensuring that the device operates within safe radio frequency energy levels. The SAR-based exemption formula of §1.1307(b)(3)(i)(B) is applied to determine if the device meets the SAR exemption criteria.
The evaluation considers separation distances between 0.5 cm and 40 cm, and frequencies from 0.3 GHz to 6 GHz. The threshold Pth (mW) is calculated using Formula (B.2). The antenna gain is 2.7 dBi, and the conducted transmit power is 0.88dBm (1.22mW). The maximum ERP power is specified as 1.43dBm (1.39mW). The source-based time-averaging conducted output power is 1.39 mW.
The SAR Exclusion Threshold Level is calculated as 2.72 mW. Since the source-based time-averaging conducted output power is below the SAR low threshold level, the device is considered to comply with SAR requirements without testing.
