5    SAR Evaluation
5.1 RF Exposure Compliance Requirement
5.1.1 Standard Requirement
     According to KDB447498D01 General RF Exposure Guidance v06
     4.3.1. Standalone SAR test exclusion considerations
           Unless specifically required by the published RF exposure KDB procedures, standalone 1-g
     head or body and 10-g extremity SAR evaluation for general population exposure conditions, by
     measurement or numerical simulation, is not required when the corresponding SAR Exclusion
     Threshold condition, listed below, is satisfied.
5.1.2 Limits
     The 1-g and 10-g SAR test exclusion thresholds 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)] ·
     [√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where

                                                                                     17



     The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and
     for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation
     distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion

 For BLE:

                                               GFSK mode
               Test channel                                  Peak Output Power (dBm)

Remark: The Conducted Peak Output Power data refer to report Report No.: CQASZ20180500101E—02


BDR, EDR and BLE can not simultaneous transmitting at same time.
      The worst case data: GFSK_lowest channel
      The Max Conducted Peak Output Power is 2.42dBm in lowest channel(2.402GHz);
      The best case gain of the antenna is —0.73dBi.
      EIRP= 2.42dBm — 0.73dBm= 1.69dBm
      1.69Bm logarithmic terms convert to numeric result is nearly 1.48mW
      According to the formula. calculate the EIRP test result:
     [{max. power of channel, including tune—up tolerance, mW)/{min. test separation distance, mm)] —
      [Nf(GHz)]
      General RF Exposure = (1.48mW /5 mm ) x v2.402GHz =0.46          ®
      SAR requirement:
      S= 3.0                                                          @;
      0 <@.
      So the SAR report is not required.
