1.2 Objective The objective of the following report is used to demonstrate that EUT operated in a manner that ensures the public is not exposed to radio frequency energy levels in excess of the relative provisions of FCC 47CFR Part 1.1307 1.3 General Description of Test Items Description EUT Frequency band FHSS: 2.400GHz ~ 2.483GHz WLAN: 2.400GHz ~ 2.483GHz WLAN: 5.18GHz ~ 5.32GHz / 5.50GHz ~ 5.70GHz WLAN: 5.745GHz ~ 5825GHz Others: __________________________ Device category Portable (<20cm separation) Mobile (>20cm separation) Others __Stationary type_ (>20cm separation)_ Exposure classification Occupational/Controlled exposure (S = 5mW/cm2) General Population/Uncontrolled exposure (S=1mW/cm2) Others: __________________________ Antenna diversity Single antenna Multiple antennas: Tx diversity Rx diversity Tx/Rx diversity Max. output power 22.99dBm(0.199W) Antenna gain (Max) 3.2dBi (Numeric gain:2.089) Evaluation applied MPE Evaluation SAR Evaluation Note: 1. The maximum output power is 22.99dBm at IEEE 802.11b mode 2462MHz (with 2.089 numeric antenna gain.) 2. For mobile or fixed location transmitters, no SAR consideration applied. The minimum separation generally be used is at least 20 cm, even if the calculations indicate that the MPE distance would be lesser. Report No.: HCT17DR084E-2 Page 4 of 6

1.4 Human Exposure Assessment Results EUT parameter (data from the separate report) Given Where G: numerical gain of transmitting antenna; TP: Transmitted power in watt; d: distance from the transmitting antenna in meter Max average output power in Watt (TP) 22.99dBm(0.199W) Max Antenna gain (G) 3.2dBi (Numeric gain:2.089) Exposure classification S=1mW/cm2 Minimum distance in meter (d) 20cm (0.2m) (from transmitting structure to the human body) Report No.: HCT17DR084E-2 Page 5 of 6

Yields 30 xPxG S , P=0.199W, G=2.089, d=0.2 3770d2 S=0.083mW/cm2 Or 30xPxG d= , S=1, P=0.199W, G=2.089 3770S d=0.057m Conclusion: S=0.083mW/cm2 is significant lower than the General Population Exposure Power Density Limit 1mW/cm2 or except the distance when human body proximity to the antenna is less than 5.6 cm then will reach the General Population Exposure Power Density Limit (For mobile or fixed location transmitters, the maximum power density is 1.0 mW / cm2 even if the calculation indicates that the power density would be larger.)
