American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 November 4, 2004 RE: Cisco-Linksys, LLC FCC ID: Q87-WGA54AG After a review of the submitted information, I have a few comments on the above referenced Application. 1) The users manual appears to be missing the information required by 15.21. Please correct. 2) Please confirm if the AC power line contains a ferrite. There appears to be a ferrite on this cable in the test photographs, but the test report (page 11) states no core was present. Please explain and correct as necessary. 3) Please confirm that the 802.11 b/g portion of the device does not contain a Turbo mode. If so additional testing may be necessary. It appears odd that only the 802.11a portion contains a turbo mode. 4) All the data on page 55 appears to be missing the negative signs according to the plots. Otherwise the data in the plots is in excess of the limits. Please review and correct as necessary. --- Continued on Next Page --- z Page 2 November 4, 2004 5) 6) Power density for 5 GHz appears to be measured using an average vs peak method. According to the FCC procedures, if the average method is employed, this should be done over 100 averages. This does not appear to have been done properly. Please review and see attached FCC procedures. 7) Compliance for the 5725 – 5825 Band appears to show some data for 15.247 and some data for 15.409. Note compliance must be completely shown to one band, the other, or both. Most data provided is for 15.247 and other data for 15.409 is NOT provided. However, it is assumed that only compliance to 15.247 is being applied. However, there are the following concern: a) All data on page 92 must be compared to 54 and 74 dBuV/m, not the -17 and -27 dBm limits. Timothy R.

FCC ID: Q87-WGA54AG Report No.RF931027L11 Technical Description The transmitter of the EUT (Wireless A/G Game Adapter) is powered by AC Adapter. The antenna type used in this product is Dipole antenna with UFL antenna connector. Under normal use condition, the user has to keep at least 20cm separation distance between radiator and the body of the user. This device is an Wireless A/G Game Adapter, which operates in both of the 5GHz and 2.4GHz bands and can transmitting simultaneously, the maximum data rate could be 54Mbps. (Part of 802.11a is capable of providing data rate of up to 108Mbps in Turbo mode) For more detailed instruction, please take a look at the user’s manual. FCC 15.407(c) states: The device shall automatically discontinue transmission in case of either absence of information to transmit or operational failure. These provisions are not intended to preclude the transmission of control or signaling information or the use of repetitive codes used by certain digital technologies to complete frame or burst intervals. Applicants shall include in their application for equipment authorization a description of hoe this requirement is met” Data transmission is always initiated by software, which is then pass down through the MAC, through the digital and analog baseband, and finally to the RF chip. Several special packets (ACKs, CTS, PSPoll, etc...) are initiated by the MAC. There are the only ways the digital baseband portion will turn on the RF transmitter, which it then turns off at the end of the packet. Therefore, the transmitter will be on only while one of the aforementioned packets are being transmitted.

FCC ID: Q87-WGA54AG Report No: SA931027L11 1 RF EXPOSURE REPORT REPORT NO.: SA931027L11 MODEL NO.: WGA54AG ACCORDING: FCC Guidelines for Human Exposure IEEE C95.1 APPLICANT: Cisco-Linksys, LLC ADDRESS: 121 Theory Drive Irvine, CA 92612, U.S.A. ISSUED BY: Advance Data Technology Corporation TEST LOCATION: No. 19, Hwa Ya 2nd Rd., Wen Hwa Tsuen, Kwei Shan Hsiang, Taoyuan Hsien 333, Taiwan, R.O.C. FCC ID: Q87-WGA54AG Report No: SA931027L11 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-WGA54AG Report No: SA931027L11 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 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 This device is not fixed inside the host equipment, it is connected with host through wire. So it is easy to be re-located in the place where at least 20cm far 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.
