Report No.: TB-MPE163298 Page: 2 of 3 MPE Calculations for WIFI 1. Antenna Gain: Internal Antenna: 3dBi. 2. 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. Test Result: Conducted Max tune up Power Turn-up ANT Gain Distance Density Power(max) power Mode Power (dBi) (cm) 2 (dBm) (dBm) (mW/ cm ) (dB) [G] [R] [P] [S] 802.11b 16.68 16±1 17 3 20 0.01989 802.11g 15.63 15±1 16 3 20 0.01580 802.11n 15.66 15±1 16 3 20 0.01580 (HT20) 802.11n 14.96 14±1 15 3 20 0.01255 (HT40) TB-RF-075-1.0

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 802.11b/g/n:2412~2462 MHz 802.11n(HT40): 2422MHz~2452MHz MPE limit S: 1mW/ cm2 The MPE is calculated as 0.01989mW / 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).
