FCC ID: NCI-VNT6656G6A4X Report No. 950210H01A Operational Description This device is a USB Embedded Module, the maximum data rate could be up to 54Mbps which OFDM technique will be applied. If the signal to noise radio is too poor which could not support 54Mbps, the 11Mbps data rate with CCK technique will be applied. The transmitter of the EUT (USB Embedded Module) is powered from host equipment. The antennas used in this product are as following: 1. The EUT can be equipped with following antennas: No.Brand NameModel No.Gain (dBi)Antenna TypeAntenna Connector 1 High-tekT700(PEN) 0.05 PIFA I-PEX 2 ARISTOTLEPCB013 1 PCB I-PEX 3 ARISTOTLEC2H Series 2.5 Monopole I-PEX 4 Own designMN003 1.29 PCB I-PEX Note: 1. From above antennas, the different type of antennas was chosen for final test and its data were recorded in this report. 2. Antenna 2 and 4 are the same type of antenna.

Report No.: SA950210H01A 1 RF EXPOSURE REPORT REPORT NO.: SA950210H01A MODEL NO.: VNT6656G6A40 FCC ID: NCI-VNT6656G6A4X ACCORDING: FCC Guidelines for Human Exposure IEEE C95.1 APPLICANT:VIA Technologies, Inc. ADDRESS:8F, 533, Chung-Cheng Rd. Hsin-Tien, Taipei 231 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.: SA950210H01A 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.: SA950210H01A 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.: SA950210H01A 4 6.
