RF EXPOSURE ANALYSIS Product FCC ID BT121 Bluetooth Module QOQBT121 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 BT121 the maximum TX power including tolerances is 13 mW and maximum TX frequency is 2.48 GHz. Using separation distance of 7 mm with the formula above results  13mW     2.48  2.92  3  7mm  For portable use the SAR exclusion condition is fulfilled and SAR evaluation is not required for BT121 with 7 mm separation distance or more. If the separation distance is less than 7 mm additional SAR evaluation will be required.
