FCC ID.: O6LTTD-VMI110 Report No.: TS13060026-EME Page 6 of 22 2. Test specifications 2.1. Introduction The EUT operates in the 2.4 GHz ISM band. Due to the EUT (include antenna) at its normal operation distance is at least 20 cm from the human body, the EUT was defined as a Mobile Device. The reason to do the MPE Evaluation is to avoid the RF hazard to human body. The maximum output power and gain of the antenna were used to calculate the limited Power density (S) at 20 cm distance away from the product. The limit for Maximum Permissible Exposure (MPE) specified in FCC 1.1310 and Safety Code 6 are followed. According to 1.1307 (b)(1), systems operating under the provisions of this section shall be operated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of the Commission’s guideline.

FCC ID.: O6LTTD-VMI110 Report No.: TS13060026-EME Page 7 of 22 2.2. RF Exposure Limit According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation as specified in 1.1307(b).

FCC ID.: O6LTTD-VMI110 Report No.: TS13060026-EME Page 9 of 22 2.3 RF Exposure calculations From §FCC 1.1310 table 1, the maximum permissible RF exposure for an uncontrolled environment is 1 mW/(cm2) (or 10 W/m2)* Power density (S) is calculated by the following formula: S = (P * G)/4πR2 where, S = Power density (mW/cm2) P = Output power to antenna (mW) R = Distance between radiating structure and observation point (cm) G = Gain of antenna in numeric π = 3.1416 Example: Assume a mobile device operates at 2412MHz and its maximum output power is 50mW, and the maximum gain of antenna is 1 (numeric) /0dBi. Then the power density (S) = (50 * 1)/4*π*202 = 0.00995 (mW/cm2) (or = 0.0995 W/m2) 2.4 Operation mode The EUT was supplied with DC 6 V from adapter (Test voltage: 120VAC / 60 Hz). Tester used “Continue_Tx/Rx command” to control the EUT. The EUT was controlled to transmit continuously during the tests. With individual verifying, the maximum output power was found out 1 Mbps data rate for 802.11b mode, 6 Mbps data rate for 802.11g mode, 6.5 Mbps data rate for 802.11n HT 20 mode and 13.5 Mbps data rate for 802.11n HT 40 mode.
