American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 October 25, 2004 RE: FCC ID: AK8PCVE21L_ATCB001840 Attention: Hiroka Umeyama I have a few comments on this Application. Please note that further comments may arise in response to answers provided to the questions below. 1. Please provide a separate MPE exhibit. 2. Please note that every application must stand on its own merit. Please provide some information on what the 2402 to 2479MHz ‘Receiver’ is. How does it work, is it a BT device? Is it a DSSS device? If so, how does it meet the SS definition? Is it a hopper? Etc. 3. Please note that the analyzer plots on pages 31, 32, 35 through 40, 72 through 77, 81 to 82, 84 to 85 and 87 to 88 are not clear and do not clearly show the analyzer settings. Please provide clear identifiable plots in the report. 4. Please note that the data tables for radiated emissions include a distance factor that is not included in the formula. Please also note that the data tables say 3/1m. What does this mean? When is it 1 meter and when is it 3 meters? This is confusing. Please show in the tables when and where this distance factor is used and please include this distance factor in your formula for final results.

October 26, 2004 Subject : FCC ID: AK8PCVE21L Dear Mr. Dennis Ward, Regarding to your comment for the above FCC ID on October 25, 2004 please find the following reply; 1. We have made MPEs. Please refer to the uploaded RF exposure statements. 2. Please refer to the uploaded technical specification (file name: CYWUSB6934) 3. We have replaced the relevant pages to the revised one. Please refer to the uploaded revised test reports for FCC and Industry Canada. 4. Please let us explain, because it might have been difficult to recognize. The formula of factor and explanation of distance has been provided in the table No.1(above ) and No.4 (below). (for example in page 58 of test report) It is also provided in second line of [Radiated] Test procedure, SECTION 8:Spurious Emission, Section 15.247(c) in page 10. Please confirm. *We assume that the uploaded files could clarify all the comments you have provided. Sincerely yours, Yoshiko Mizuta (Ms.) UL Apex Co., Ltd.

This calculation is based on the highest EIRP possible from the system, considering maximum power and antenna gain, and considering a 1.0mW/cm^2 uncontrolled exposure limit. The Friis formula used was: 1. WLAN S = (P * G) / (4* * r 2 ) Where P = 216.27mW (Maximum peak output power) G = 1.25Numerical Antenna gain; equal to0.98 r =20.0 cm S =0.05392mW/cm 2 No. : 25BE0202-HO-2 RF Exposure / SAR Statement 2. Receiver S = (P * G) / (4* * r 2 ) Where P = 0.91mW (Maximum peak output power) G = 1.64Numerical Antenna gain; equal to2.14 r =20.0 cm S =0.00030mW/cm 2 3. Total ( 1.WLAN + 2.Receiver ) S ( Receiver ) = 0.05392mW/cm 2 S ( WLAN ) = 0.00030mW/cm 2 For: PCV-E21L S ( Total ) = 0.05422mW/cm 2
