FCC ID: Q87-WRT54GSV7 Report No. RF951204H06 Operational Description This device is a Wireless-G Broadband Router With 4-Port Switch, 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 (Wireless-G Broadband Router With 4-Port Switch) is powered by power adapter. The antennas used in this product is Dipole antenna with Reversed-TNC connector. The other instruction, please have a look at the users manual.

Report No.: SA951204H06 1 RF EXPOSURE REPORT REPORT NO.: SA951204H06 MODEL NO.: WRT54GS V7 FCC ID: Q87-WRT54GSV7 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 LOCATION: No. 81-1, Lu Liao Keng, 9 Ling, Wu Lung Tsuen, Chiung Lin Hsiang, Hsin Chu Hsien, Taiwan, R.O.C. Report No.: SA951204H06 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/300 6 1500-100,000 ... ... 5 6 (B)Limits For General Population / Uncontrolled Exposure 300-1500 ... ... F/1500 6 1500-100,000 ... ... 1.0 30 F = Frequency in MHz Report No.: SA951204H06 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.: SA951204H06 4 6. Test Results 6.1 Antenna Gain The maximum Gain measured in Fully Anechoic Chamber is 2.0dBi or 1.58489 (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 ) 1 2412 134.896 0.043 1.0 6 2437 134.896 0.043 1.0 11 2462 107.152 0.034 1.0 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 ) 1 2412 134.896 0.043 1.0 6 2437 134.896 0.043 1.0 11 2462 120.226 0.038 1.0
