Operational Description WIDT20R is the 802.11a/b/g/n RF Module, that acts as a communication hub for users of a wireless device to connect to a wired LAN. MIMO type Product type: WLAN (11b mode: 1TX, 1RX, 11g mode: 1TX, 1RX, n mode: 2TX, 2RX) Time base of the transmission frequency For IF and RF frequency, Crystal is a clock reference. Synthesizer Synthesizer inside Transceiver. Internal voltage controlled oscillator (VCO) provides the desired LO signal base on the phase-locked loop (PLL) with a relatively wide tuning range for this application. Transmission Base-band Processing (BBP) IC has DSSS (BPSK/QPSK/CCK) and OFDM (BPSK/QPSK/16QAM/64QAM) modulation function, it provides transmission data rate are 1, 2, 5.5, 11 Mbps on DSSS and 6, 12, 18, 24, 36, 48, 54 Mbps on OFDM. Digital data signal will be converted to analog (TX IQ) signals through DAC in BBPIC, TX IQ pass through to low pass filter. TX I/Q signal use direct conversion (zero-IF) architecture converter to generate carrier frequency signal. Transceiver IC and internal PA magnify output power. Receiver Reverse direction isolation of LNA inside Transceiver IC suppresses unwanted radiation. Then RF signal will be directly down to IF signal (RX IQ) and high frequency spurious emissions are suppressed by LPF. At last RX IQ signal will be demodulated digital data. Base band Processing 1. Channel selection is controlled by BBP IC to support data modulation: - DSSS (BPSK/QPSK/CCK) - OFDM (BPSK/QPSK/16QAM/64QAM) Power Control Level It uses closed-loop power control function to limit RF output power level. Transmit/Receive Switch EUT has Transmit/Receive Switch and Antenna switch. End user can’t select any power setting. Channel Selection Restriction For product available in the USA/Canada/Taiwan market, only channel 1~11 can be operated. Selection of other channels is not possible. But product also could be available in the Europe/Japan market, channel 1~13 can be operated under the manufacturer change the different driver. Data Rate Control The operation date rate is changing during data transfer base on the optimization of driver. Discontinue Transmitting with absence of Data or operational failure states “The device shall automatically discontinue transmission in case of either absence of information to transmit or operational failure. These provisions are not intended to preclude the transmission of control or signaling information or the use of repetitive codes used by certain digital technologies to complete frame or burst intervals. Applicants shall include in their application for equipment authorization a description of how this requirement is met.” Data transmission is always initiated by software, which is then passed down through the MAC, through the digital and analog baseband, and finally to the RF chip. Several special packets (ACKs, CTS, PSPoll, etc...) are initiated by the MAC. These are the only ways the digital baseband portion will turn on the RF transmitter, which it then turns off at the end of the packet. Therefore, the transmitter will be on only while one of the aforementioned packets is being transmitted.

RF Exposure Evaluation 2.1 Environmental evaluation and exposure limit according to FCC CFR 47 part 1, 1.1307(b), 1.1310 According to FCC 1.1310 : The criteria listed in the following table shall be used to evaluate the environment impact of human exposure to radio frequency (RF) radiation as specified in §1.1307(b) LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) 2.1.1. Friis transmission formula: Pd = (Pout*G)/(4*pi*R 2 ) Where Pd = power density in ㎽/㎠ Pout = output power to antenna in ㎽ G = gain of antenna in linear scale Pi = 3.1416 R = distance between observation point and center of the radiator in ㎝ Pd the limit of MPE, 1 ㎽/㎠. If we know the maximum gain of the antenna and the total power input to the antenna, through the calculation, we will know the distance where the MPE limit is reached. Frequency Range (㎒) Electric Field Strength(V/m) Magnetic Field Strength (A/m) Power Density (㎽/㎠) Average Time (A) Limits for Occupational /Control Exposures 300 – 1 500 -- -- F/300 6 1 500 – 100 000 -- -- 5 6 (B) Limits for General Population/Uncontrol Exposures 300 – 1 500 -- -- F/1500 30 1 500 – 100 000 -- -- 1 30 Report Number : F690501/RF-RTL005221-1 Page: 7 of 13 The results shown in this test report refer only to the sample(s) tested unless otherwise stated.
