FCC ID: Q87-WUSB54GX4 Report No.: RF950302L10 Technical Description The Wireless-G USB Network Adapter with SRX400 combines smart antenna technology with standards-based Wireless-G (802.11g) networking. 1. The EUT incorporates a MIMO function with IEEE 802.11b/g. Physically, the card provides two complete transmitter and two receivers. 2. The EUT is 2*2 spatial MIMO (2TX & 2RX) without beam forming function that only operate dual chain configuration (both chain 0 and chain 1 transceivers are operational). 3. When the EUT operates in OFDM (SIMO) mode, the transfer rate of transmitting is up to 54Mbps. When the EUT operates in OFDM (MIMO) mode, the transfer rate of transmitting is up to 126Mbps. 4. When the EUT operates in ACE-OFDM (SIMO) mode, the transfer rate of transmitting is up to 126Mbps. When the EUT operates in ACE-OFDM (MIMO) mode, the transfer rate of transmitting is up to 240Mbps. (ACET: Adaptive Channel Expansion Technology) 5. The "SIMO" mean both TX chains transfer same packet data during operating and " MIMO " mean both TX chains transfer different packet data. The transmitter of the EUT is powered by host equipment. The antenna is Dipole antenna with UFL connector. The other instruction, please have a look at the users manual.

FCC ID: Q87-WUSB54GX4 Report No: SA950420L10 1 RF EXPOSURE REPORT REPORT NO.: SA950302L10 MODEL NO.: WUSB54GX4 ACCORDING: FCC Guidelines for Human Exposure IEEE C95.1 APPLICANT: Cisco-Linksys LLC ADDRESS: 121 Theory Drive Irvine, CA 92617 (USA) ISSUED BY: Advance Data Technology Corporation LAB ADDRESS: No. 47, 14 th Ling, Chia Pau Tsuen, Lin Kou Hsiang 244, Taipei Hsien, Taiwan, R.O.C. TEST LOCATION: No. 19, Hwa Ya 2 nd Rd., Wen Hwa Tsuen, Kwei Shan Hsiang, Taoyuan Hsien 333, Taiwan, R.O.C. FCC ID: Q87-WUSB54GX4 Report No: SA950420L10 2 RF EXPOSURE MEASUREMENT (MOBILE DEVICE) 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 FCC ID: Q87-WUSB54GX4 Report No: SA950420L10 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 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 r. 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 This device is fixed inside the host equipment. 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: Q87-WUSB54GX4 Report No: SA950420L10 4 6.
