RF EXPOSURE ANALYSIS Product FCC ID WT11u Bluetooth Module QOQWT11U Analysis for FCC, portable use Standalone SAR test exclusion considerations are defined in the KDB 447498 Chapter 4.3.1. 1-g head or body SAR exclusion threshold is defined with formula [(max . power of channel, including tun-up tolerance, mW)/(min. separation distance, mm.)]* (√f(GHz))≤3 For WT11U the maximum TX power including tolerances is 80 mW and maximum TX frequency is 2.48 GHz. Using separation distance of 42 mm with the formula above results  80mW     2.48  2.9997  3  42mm  Thus WT41U meets the SAR exclusion criteria with 42 mm separation and SAR evaluation is not needed if the minimum separation distance to human body is more than 42mm.
