The SAR Test Exclusion Threshold for frequencies in the range 100 MHz to 6 GHz, and for test separation distance of ≤ 50 mm, is determined as follows. SAR Exclusion Threshold (SARET) = (NT x TSD A ) / √ f GHz Where, NT = Numeric Threshold (3.0 for 1-g SAR and 7.5 for 10-g SAR) TSDA = Minimum Test separation distance or 50 mm (whichever is lower) fGHz = Transmit frequency in GHz BLE Handheld standalone operation Radio Channel Frequency (MHz) Maximum Conducted Power (mW) SAR Exclusion Threshold at 5 mm (mW) SAR Evaluation BLE 2402 - 2480 4.0 9.7 Not Required Note 1: This assessment is based on the manufacturer’s rated power. Note 2: This assessment is based on 100% duty cycle, Therefore standalone SAR evaluation for general population exposure conditions by measurement or numerical simulation is not required.
