RF EXPOSURE ANALYSIS Product FCC ID IC Number BLE121LR QOQBLE121LR 5123A-BGTBLE121LR 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 BLE121LR the maximum TX power including tolerances is 9 mW and maximum TX frequency is 2.48 GHz. Using separation distance of 5 mm with the formula above results  9mW     2.48  2.83  3  5mm  According to KDB 447498, if the separation distance is less than 5mm, then 5mm separation distance is used to calculate the RF exposure. Thus BLE121LR meets the SAR exclusion criteria with 0 mm separation and SAR evaluation is not needed.
