American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 November 6, 2002 RE: Accton Technology Corporation FCC ID: HED3CRSHPW796 After a review of the submitted information, I have a few comments on the above referenced Application. 1) The block diagram should show the frequencies of all oscillators in the device (CFR 2.1033(a)(5)) not just the transmit channels. Please provide an updated version that includes this information. 2) Please explain the purpose of the copper tape to the external part of the unit. How will this be implemented into production models. 3) The operational description/RF exposure/Users Manual exhibits explain that the device is to be used with 2.5 cm spacing. The device may be used as a general purpose PCMCIA card in a variety of devices including laptops & PDA's, etc. (some of these devices may be used in the lap or while on the body). Therefore touch position IS considered applicable and the device must be subject to portable exposure conditions (2.5 cm separation distance is NOT considered applicable). Please provide a corrected operational description. 4) Please remove the phrase " In order to comply with FCC radio-frequency radiation exposure compliance requirements, a separation distance of at least 2.5 cm (1.0 inch) must be maintained between the antenna of the device and all persons." from the users manual since it is not considered applicable. 5) The operational description mentions a modular approval and mobile applications specific to access points, etc. Please explain. 6) Maximum power is not listed correctly on page 6 of the test report. This should be 12.70 dBm. Please correct. 7) Section 4.6.6 is not calculated for the worse case margin on the low side of the bandedge. Please add these calculations to the report. 8) The gain specified in the test report section 4.7 is 0.8 dBi, while the RF exposure lists 0.0 dBi. Which is correct? Please correct the affected exhibits. Timothy R. Johnson Examining Engineer 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.

Dear Tim, FCC ID: HED3CRSHPW796 I will re-submit the revised vision of RF exposure, FCC test report and Operation Description as soon as possible. And for explain, the question that u pointed out about the purpose of copper tape: Explaination: The copper tape is used for the countermeasure of EMI, it will be implement into the inner side of the product to enhance the grouding.

FCC ID: HED3CRSHPW796 ADT No.911008R06 Operational Description The transmitter of the EUT (OfficeConnect ® 11Mbps Wireless LAN Cardbus PC Card) is powered by host equipment. The antenna is Printed antenna without connector. The other instruction, please have a look at the users manual. DSSS Information This device is Direct Sequence Spread Spectrum, the data is mixed by pseudorandom code which is an orthogonal code. The mixed data is digital modulated by BPSK and QPSK technique depends on the data rates. The CCK coding is applied for increasing the data rate, and also the processing gain will be increased. The bit rates are 1,2,5.5,11Mbps, the symbol rates are 1,1,1.375,1.375Mbps, the chip rates are always 11Mbps. So, the Chip/symbol is 11,11,8 and 8 respectively. Although is higher bit rate, the processing gain is lower than 10, but the CCK coding used in higher bit rate will provide 2.2dB coding gain.

FCC ID: HED3CRSHPW796 ADT No.: 911008R06 FCC TEST REPORT REPORT NO.: RF911008R06 MODEL NO.: 3CRSHPW796 ACCORDING: FCC Guidelines for Human Exposure IEEE C95.1 APPLICANT:ACCTON TECHNOLOGY CORPORATION ADDRESS: No.1, Creation Rd., III, Science-Based Industrial Park, Hsinchu, Taiwan, R.O.C. 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: HED3CRSHPW796 ADT No.: 911008R06 RF Exposure Measurement (Portable Device) 1. Introduction 2.4 GHz 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. 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: HED3CRSHPW796 ADT No.: 911008R06 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 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 distance r where the MPE limit is reached. 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. FCC ID: HED3CRSHPW796 ADT No.: 911008R06 5. Test Results 5.1 Antenna Gain The maximum Gain measured in Fully Anechoic Chamber is 0.8 dBi or 1 (numeric). 5.2 Output Power Into Antenna & RF Exposure Distance : CHANNEL CHANNEL FREQUENCY (MHz) OUTPUT POWER TO ANTENNA (mW) MINIMUM ALLOWABLE DISTANCE ( r ) FROM SKIN (Centi-Meter) 1241217.381.29 6243718.371.33 11246218.621.33 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.
