FCC ID: 2AC23WF7E INTERTEK TESTING SERVICES RF Exposure report The Equipment Under Test (EUT) is a WiFi Module with WiFi function operating at 2412-2462MHz for 802.11b/g/n-HT20, 11 channels with 5MHz channel spacing and 2422-2452MHz for 802.11n-HT40, 9 channels with 5MHz channel spacing. The EUT was powered by DC 3.3V, 300mA. For more detailed features description, please refer to the user’s manual. Modulation Type: BPSK, QPSK, 16QAM, 64QAM, CCK, DQPSK, DBPSK. An tenna Type: Integral antenna Antenna Gain: -1.0dBi The nominal conducted output power specified: 10dBm (Tolerance: +/-4dB) The maximum conducted output power for the EUT is 12.8dBm in the frequency 2.412GHz 802.11g mode which is within the production variation. The minimum conducted output power for the EUT is 6.6dBm in the frequency 2.462GHz 802.11b mode which is within the production variation. According to FCC Part 2.1091, this unlicensed transmitting devices is categorically excluded from routine environmental evaluation for RF exposure prior to equipment authorization or use, According to the KDB 447498 and OET 65, the simple calculation as below: For Maximum Permissible Exposure (MPE) evaluation of the product, the maximum power density at 20 cm from this transmitter shall be less than the General Population / Uncontrolled MPE limit in FCC Part 1.1310. Th e maximum E.I.R.P= 10+4-1=13dBm=19.95mW The source-based time averaged maximum radiated power = 19.95 x Duty Cycle = 19.95mW From above data, the exposed power density at a distance (R) of 20cm from the center of radiation of the antenna can be calculated as follow: = 19.95 / 4πR^2 = 0.004 mW/cm^2 FCC ID: 2AC23WF7E The MPE limit is 1.0 mWcm-2 for general population and uncontrolled exposure in the WiFi frequency range according to FCC Part 1.1310. As the measured power density at 20cm from the transmitter is lower than the MPE limit, the compliance to the MPE limit can be ensured by indicating the minimum 20cm separation between the transmitter's radiating structure and body of the user or nearby persons. Transmitter Duty Cycle Calculation The EUT transmit continuously during the test, the duty cycle is 1. The following RF exposure statement or similar sentence is proposed to be included in the user manual: “FCC RF Radiation Exposure Statement Caution: This Transmitter must be installed to provide a separation distance of at least 20 cm from all persons.”
