EUT Operation Condition: Software provided by client enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. 3. Exposure Evaluation: Equation from page 18 of OET Bulletin 65, Edition 97-01 S=(PG)/4πR2 Where S: power density P: power input to the antenna G: power gain of the antenna in the direction of interest relative to an isotropic radiator. R: distance to the center of radiation of the antenna 4.

Report No.: TB-MPE167628 Page: 4 of 4 5. Conclusion: As specified in Table 1B of 47 CFR 1.1310- Limits for Maximum Permissible Exposure (MPE), Limits for General Population/ Uncontrolled Exposure Frequency Range Power density (MHz) (mW/ cm2) 300-1,500 F/1500 1,500-100,000 1.0 For BT:2402~2480 MHz For WIFI:2412~2462 MHz MPE limit S: 1mW/ cm2 The MPE is calculated as 0.0171mW / cm2 < limit 1mW / cm2. So, RF exposure limit warning or SAR test are not required. The EUT will only be used with a separation of 20cm or greater between the antenna and nearby persons and can therefore be considered a mobile transmitter per 47 CFR2.1091 (b). The RF Exposure Information page from the manual is included here for reference.
