FCC ID: PD9-R900531 ADT Number: 900626R04 1 FCC TEST REPORT REPORT NO.: RF900626R04 MODEL NO.: WLGW2011BAK ACCORDING: FCC Guidelines for Human Exposure IEEE C95.1 APPLICANT:Intel Corporation ADDRESS: 15250 Avenue of Science, SN1-02, San Diego, CA 92128 ISSUED BY:Advance Data Technology Corporation LAB LOCATION:47 14th Ling, Chia Pau Tsuen, Linkou Hsiang, Taipei, Taiwan, R.O.C. 0528 Lab Code: 200102-0 FCC ID: PD9-R900531 ADT Number: 900626R04 2 RF Exposure Measurement 1. Introduction 2.4 GHz frequency band is regarded specially as a dangerous band for its heating harmfulness to the human body. That’s why microwave oven is operating in this frequency band. The manufacturer whose product is working in this frequency band is obligatory to prove the harmfulness of his product. In this document, we try to prove the safety of radiation harmfulness to the human body for our product. The limit for Maximum Permissible Exposure (MPE) specified in FCC 1.1310 is followed. The Gain of the antenna used in this product is measured in a Fully Anechoic Chamber (FAC) calibrated for antenna measurement in ADT, and also the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. Although the Friis transmission formula is a far field assumption, the calculated result of that is an over-prediction for near field power density. We will take that as the worst case to specify the safety range. 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) LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm 2 ) Average Time (minutes) (A)Limits For Occupational / Control Exposures 300-1500......F/3006 1500-100,000......56 (B)Limits For General Population / Uncontrolled Exposure 300-1500......F/15006 1500-100,000......1.030 F = Frequency in MHz FCC ID: PD9-R900531 ADT Number: 900626R04 3 3. Friis Formula Friis transmission formula : Pd = (Pout*G) / (4*pi*r 2 ) where Pd = power density in mW/cm 2 Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 R = distance between observation point and center of the radiator in cm Pd is the limit of MPE, 1 mW/cm 2 . 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 r where the MPE limit is reached. Ref. : David K. Cheng, Field and Wave Electromagnetics, Second Edition, Page 640, Eq. (11-133). 4 EUT Operating condition The software provided by Manufacturer enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. 5 Climate Condition The temperature and related humidity: 30 deg. C and 60 % RH 6. Classification This device is not fixed inside the host equipment, it is connected with host through wire. So it is easy to be re-located in the place where at least 20 cm far away from the body of the user. Warning statement to the user for keeping at least 20cm or more separation distance with the antenna should be included in users manual. So, this device is classified as Mobile Device. FCC ID: PD9-R900531 ADT Number: 900626R04 4 7 Test Results 7.1 Antenna Gain The maximum Gain measured in Fully Anechoic Chamber is 1dBi or 1.26 (numeric). 7.2 Output Power Into Antenna & RF Exposure Distance : CHANNEL CHANNEL FREQUENCY (MHz) EIRP OUTPUT POWER TO ANTENNA (mW) MINIMUM ALLOWABLE DISTANCE ( r ) FROM SKIN (Centi-Meter) 124127.110.84 6243710.591.01 11246211.431.03 The minimum allowable distance is very close to the enclosure of the antenna. So, the user has no need to worry about the harmfulness of radiation. But it is recommended to always keep, at least, 20 cm separation distance with the antenna.

Section 4.7.4 shows the test configuration. The test consists of stepping a signal generator in 50 kHz increments across the passband of the system. At each point, the generator level required to produce the recommended Bit Error Rate (BER) is recorded. This level is jammer level. The output power of the transmitting unit is measured at the same point. The jammer to Signal (J/S) ratio is then calculated. Discard the worst 20% of the J/S data points. The lowest remaining J/S ratio is used when calculating the Process Gain. The reference PER is specified as 8%. The corresponding Es/No (signal to noise ratio per symbol) is 16.4 dB. The curve is attached as below. This value and the measured J/S ratio are used in the following equation to calculate the Process Gain (Gp) of the system. Where: (S/N) o : Signal to noise ratio for the chosen BER. Gp = (S/N)+Mj+Lsys FCC ID: PD9-R900531 Report No.: RF900626R04 3 Issued: July 27, 2001 Mj : Maximum jammer to Signal Ratio recorded at the detected BER. Lsys : System losses .

Perform all independent instrumentation calibrations prior to this procedure. Set operating power levels using fixed and variable attenuators in system to meet the following objectives: Signal Power at receiver approximately –55dBm (above thermal sensitivity such that thermal noise does not cause bit errors. Signal Power at power meter between –20 and –30dBm for optimal linearity. Use spectrum analyzer to monitor test. Ensure that CW Jammer generator RF output is disabled and measure the power at the power meter port using the power meter. This is the relative signal power, Sr. Disable Transmitter, and set CW Jammer generator RF output frequency equal to the carrier frequency and enable generator output. Set reference CW Jammer power level at power meter port 8.4dB below Sr (minimum J/S, or 10dB processing gain reference level). Note the power level setting on the generator, this is the reference CW Jammer power setting, Jr. Disable CW Jammer, re-establish link. PER test should be operating essentially error -free. Enable CW Jammer at the reference power level and verify that the PER test indicates a PER of less than 8%. Alternatively, adjust the CW Jammer level to that which causes 8% PER and verify that the S/J is less than 8.4dB. Repeat step 7 for uniform steps in frequency increments of 50 kHz across the receiver passband with the CW Jammer. In this case the receiver passband is +/- 8.5 MHz. The numerical data associated with the following radio channel is tabulated and presented for Channel 1,6, and 11. Note:Since the jamming signal will be blocked by the IF filter if the jamming frequency is far form the center of the carrier frequency. So, only those frequencies around carrier frequency are shown here.
