The USB interface provides 5VDC, so there are regulators in front of these chips, the part number of this regulator is XC9223B. 4. “The modular transmitter must comply with the antenna requirements of section 15.203 and 15.204(C).” The EUT meets the FCC antenna requirements. The spurious emission, unique antenna connector and photo of antennas are shown in the test report. 5. “The modular transmitter must be tested in a stand-alone configuration” The EUT was placed on an extended card which connected to Notebook Computer as a stand-alone configuration. The EUT was tested via the outside a Notebook Computer. Please see section Photographs of Test Configuration in the test report. 6. “The modular transmitter must be labeled with its own FCC ID number.” Please see exhibition Label Sample for the FCC ID of this module. And also in the exhibition Users Manual, there are instructions give to the OEM on how to label the end product. FCC ID: RRK2005070154-1 Report No. RF950831H04 7. “The modular transmitter must comply with any specific rule or operating requirements applicable to the transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements.” The EUT is compliant with all applicable FCC rules. Detail instructions for maintaining compliance are given in the Users Manual. 8. “The modular transmitter must comply with any applicable RF exposure requirements.” The EUT is compliant with all applicable RF exposure requirements. RF Exposure is addressed in the RF exposure exhibition. Please contact me if you have any further questions. Thanks for your attention.

Report No.: SA950831H04 1 RF EXPOSURE REPORT REPORT NO.: SA950831H04 MODEL NO.: WUS-G09V, WUS-G09PB, WUGC-100 FCC ID: RRK2005070154-1 ACCORDING: FCC Guidelines for Human Exposure IEEE C95.1 APPLICANT: Alpha Networks Inc. ADDRESS: No.8 Li-shing 7th Rd., Science-based Industrial Partk, Hsinchu, Taiwan, R.O.C. ISSUED BY: Advance Data Technology Corporation LAB LOCATION: No. 81-1, Lu Liao Keng, 9 Ling, Wu Lung Tsuen, Chiung Lin Hsiang, Hsin Chu Hsien, Taiwan, R.O.C. Report No.: SA950831H04 2 RF Exposure Measurement 1. Introduction 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 Report No.: SA950831H04 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 MPE value at distance 20cm. 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. Classification The antenna of this product, under normal use condition, is at least 20cm 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 Report No.: SA950831H04 4 6. Test Results 6.1 Antenna Gain The maximum Gain measured in Fully Anechoic Chamber is 1.2dBi or 1.318257 (numeric) 6.2 Output Power Into Antenna & RF Exposure value at distance 20cm: For Part 802.11b: Channel Channel Frequency (MHz) Output Power to Antenna (mW) Power Density (mW/cm 2 ) Limit of Power Density (mW/cm 2 ) 1241274.6450.0201.0 6243772.4440.0191.0 11246267.9200.0181.0 For Part 802.11g: Channel Channel Frequency (MHz) Output Power to Antenna (mW) Power Density (mW/cm 2 ) Limit of Power Density (mW/cm 2 ) 1241299.0830.0261.0 62437139.3160.0371.0 11246271.7790.0191.0
