For this device, the BT and Wi-Fi can transmit simultaneous with other transmitters. 12.2 Transmit Antenna Separation Distances Picture 12.1 Antenna Locations ©Copyright.

The 1-g SAR test exclusion threshold for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)] ꞏ [√f(GHz)] ≤ 3.0 for 1-g SAR, where  f(GHz) is the RF channel transmit frequency in GHz  Power and distance are rounded to the nearest mW and mm before calculation  The result is rounded to one decimal place for comparison Table 12.1: Standalone SAR test exclusion considerations SAR test RF output power exclusion SAR test Band/Mode F(GHz) Position threshold dBm mW exclusion (mW) Head 9.6 8 6.31 Yes Bluetooth 2.441 Body 19.2 8 6.31 Yes Head 9.58 20.5 112.20 No 2.4GHz WLAN 802.11 b 2.45 Body 19.17 20.5 112.20 No ©Copyright.

The ratio is determined by (SAR1 + SAR2)1.5/Ri, rounded to two decimal digits, and must be ≤ 0.04 for all antenna pairs in the configuration to qualify for 1-g SAR test exclusion.

When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion Conclusion: According to the above tables, the sum of reported SAR values is<1.6W/kg. So the simultaneous transmission SAR with volume scans is not required. ©Copyright. All rights reserved by CTTL.

The distance is 10/15 mm and just applied to the condition of body worn accessory. It is performed for all SAR measurements with area scan based 1-g SAR estimation (Fast SAR). A zoom scan measurement is added when the estimated 1-g SAR is the highest measured SAR in each exposure configuration, wireless mode and frequency band combination or more than 1.2W/kg. The calculated SAR is obtained by the following formula: ⁄ Reported SAR Measured SAR 10 Where PTarget is the power of manufacturing upper limit; PMeasured is the measured power in chapter 11.
