The Wireless-G Music Bridge allows you to listen to digital music in your living room as well as on your computer. How does the Music Bridge do all of this? The Linksys Wireless-G Music Bridge lets you bring the digital music streaming to or stored on your computer to your Home Entertainment Center without running cables through the house. Using a wireless connection, the Music Bridge finally frees your digital music collection from those little computer speakers to play in full glory through your stereo or surround sound system. The Wireless-G Music Bridge sits by your home stereo and connects to it using standard consumer electronics cables. Then it connects to your home network by Wireless-G wireless networking, or if you prefer, it can be connected via standard 10/100 Ethernet cabling. The included software creates a virtual sound system in your PC, which sends the audio output of any application to the Music Bridge and the stereo system. Use your favorite media player to play your music while listening in the comfort of your living room. Use the instructions in this Guide to help you connect the Wireless-G Music Bridge, set it up, and configure it to bridge your music networks. These instructions should be all you need to get the most out of the Wireless-G Music Bridge. 2 Chapter 1: Introduction What’s in this Guide? Wireless-G Music Bridge What’s …

FCC ID: Q87-WMB54G Report No.: RF940608L03 Operational Description This device is a Wireless-G Music Bridge which operates in the 2.4GHz frequency spectrum with throughput of 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 DSSS technique will be applied. The transmitter of the EUT is powered by AC adapter. The antenna is Dipole antenna with UFL antenna connector. The other instruction, please have a look at the users manual.

FCC ID: Q87-WMB54G Report No: SA940608L03 1 RF EXPOSURE REPORT REPORT NO.: SA940608L03 MODEL NO.: WMB54G 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, 14th Ling, Chia Pau Tsuen, Lin Kou Hsiang 244, Taipei Hsien, Taiwan, R.O.C. TEST LOCATION: No. 19, Hwa Ya 2nd Rd., Wen Hwa Tsuen, Kwei Shan Hsiang, Taoyuan Hsien 333, Taiwan, R.O.C. FCC ID: Q87-WMB54G Report No: SA940608L03 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-WMB54G Report No: SA940608L03 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 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. FCC ID: Q87-WMB54G Report No: SA940608L03 4 6.
