The mini-pci interface provides 3.3VDC, so there are regulators in front of these chips, the part number of this regulator is ISL6411IR. 4. “The modular transmitter must comply with the antenna requirements of section 15.203 and 15.204(C).” The EUT meets the FCC antenna requirements. The spurious emission, unique antenna connector and photo of antennas are shown in the test report. 5. “The modular transmitter must be tested in a stand-alone configuration” The EUT was tested in a stand-alone configuration via a PCMCIA to mini-PCI extender. Please see section Photographs of Test Configuration in the test report, the EUT was plugged in this extender. 6. “The modular transmitter must be labeled with its own FCC ID number.” Please see exhibition Label Sample for the FCC ID of this module. And also in the exhibition Users Manual, there are instructions give to the OEM on how to label the end product. FCC ID: Q87-WM54G-I Report No.920408R03B 7. “The modular transmitter must comply with any specific rule or operating requirements applicable to the transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements.” The EUT is compliant with all applicable FCC rules. Detail instructions for maintaining compliance are given in the Users Manual. 8. “The modular transmitter must comply with any applicable RF exposure requirements.” The EUT is compliant with all applicable RF exposure requirements. RF Exposure is addressed in the RF exposure exhibition. Please contact me if you have any further questions. Thanks for your attention. Best Regards, Dr. Alan Lane J. VP Advance Data Technology

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 July 24, 2003 RE: FCC ID: Q87-WM54G-I Attention: Ellis Wu I have a few comments on this Application. 1. Please note that the device can be either a module restricted to mobile use, or it can be a LMA in a specific type of host. Please correct your modular request letter to reflect modular not LMA (i.e. ‘authorization as a modular approval specific to mobile devices such as access points and routers”) 2. Please note that the manual states the device operates at 14dBm +/- 1 dB (see page 35 of the manual). The report clearly states that the device is a 19.97dBm and 17.88dBm conducted (see page 6 and 41 of the report. Please make your manual reflect the actual conducted values reported +/- 1dB. 3. Please note that your operational description is not correct. The application is for modular approval, not limited modular approval. Please correct the operational description to reflect the actual application for the device. 4. Please confirm that channels 12 and 13 (those channels above 2462MHz) cannot be software selected by the installer or user. 5. Dennis Ward mailto:[email protected] The items indicated above must be submitted before processing can continue on the above referenced application. Failure to provide the requested information may result in application termination. Correspondence should be considered part of the permanent submission and may be viewed from the Internet after a Grant of Equipment Authorization is issued. Please do not respond to this correspondence using the email reply button. In order for your response to be processed expeditiously, you must submit your documents through the AmericanTCB.com website. Also, please note that partial responses increase processing time and should not be submitted. Any questions about the content of this correspondence should be directed to the sender.

FCC ID: Q87-WM54G-I Report No.920408R03B Operational Description This device is a Wireless-G ISL Module which operates in the 2.4GHz band, 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. This project is seeking the authorization of module approval specific to the mobile device such as access point and router. The transmitter of the EUT is powered by host equipment via a mini-PCI interface. The antenna type used in this product is Dipole antenna with MMCX antenna connector. The other instruction, please have a look at the users manual.

FCC ID: Q87-WM54G-I Report No.: 920408R03B FCC TEST REPORT REPORT NO.: RF920408R03B MODEL NO.: WM54G ACCORDING: FCC Guidelines for Human Exposure IEEE C95.1 APPLICANT: Cisco-Linksys, LLC ADDRESS: 17401 Armstrong Ave., Irvine, CA 92614 ISSUED BY: Advance Data Technology Corporation LAB LOCATION: 47 14th Lin, Chiapau Tsun, Linko, Taipei, Taiwan, R.O.C. 0528 ILAC MRA Lab Code: 200102-0 FCC ID: Q87-WM54G-I Report No.: 920408R03B RF Exposure Measurement (Mobile Device) 1. Introduction 2.4GHz frequency band is regarded specially as a dangerous band for its heating harmfulness to the human body. That’s why microwave oven is operating in this frequency band. The manufacturer whose product is working in this frequency band is obligatory to prove the harmfulness of his product. 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), and 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. 2. Classification The antenna of the product, under normal use condition, is at least 20cm away from the body of the user. Warning statement for keeping 20cm separation distance and the prohibition of operating next to a person has been printed on the user’s manual. So, this product is classified as the Mobile Device. 3. 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). FCC ID: Q87-WM54G-I Report No.: 920408R03B 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 30-30061.40.1631.06 300-1500......F/3006 1500-100,000......56 (B)Limits For General Population / Uncontrolled Exposure 30-30027.50.0730.230 300-1500......F/150030 1500-100,000......1.030 F = Frequency in MHz 4. 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 distance r where the MPE limit is reached. Ref. : David K. Cheng, Field and Wave Electromagnetics, Second Edition, Page 640, Eq. (11-133). 5. EUT Operating condition The software provided by Manufacturer enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. FCC ID: Q87-WM54G-I Report No.: 920408R03B 6. Test Results 6.1 Antenna Gain The maximum Gain measured in Fully Anechoic Chamber is 2dBi or 1.58 (numeric). 6.2 Output Power Into Antenna & RF Exposure Distance : For 802.11b: CHANNEL CHANNEL FREQUENCY (MHz) OUTPUT POWER TO ANTENNA (mW) MINIMUM ALLOWABLE DISTANCE ( R ) FROM SKIN (Centi-Meter) 1241242.0732.302 6243761.3762.781 11246249.8882.507 For 802.11g: CHANNEL CHANNEL FREQUENCY (MHz) OUTPUT POWER TO ANTENNA (mW) MINIMUM ALLOWABLE DISTANCE ( R ) FROM SKIN (Centi-Meter) 1241276.5593.106 6243799.3113.538 11246258.4792.715 The minimum allowable distance is very close to the enclosure of the antenna and is very far away from the human being under normal use condition.
