RF EXPOSURE ANALYSIS Product FCC ID WGM110 WiFi Module QOQ-WGM110 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 BGM111 the maximum TX power is 40 mW and maximum TX frequency is 2.48 GHz. Using separation distance of 21 mm with the formula above results  40mW     2.48  2.9996  3  21mm  According to KDB 447498, if the separation distance is less than 5mm, then 5mm separation distance is used to calculate the RF exposure. Thus BGM111 meets the SAR exclusion criteria with 0 mm separation and SAR evaluation is not needed. Analysis for FCC, mobile use E.
