FCC ID: NKRUSB400 WLAN USB Adapter

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 February 2, 2003 RE:

Winston Ne Web FCC ID:

NKRUSB400 I have a few comments on this Application. In the future, please segregate photographs into External and Internal exhibits. 1.) 2.) Although there are two oscillators listed on the block diagram, the diagram seems to not comply with the provisions of 2.1033(a)(5) where the signal path and frequency shall be listed at each block. Please review. 3.) Two manuals were uploaded. Which one should be used for review? I examined the most recent upload according to the date the files was created on our server. That one has references to 20cm separation distance between the user and device. This is not appropriate when a SAR report is presented. 4.) The Schematics reference an Optional Populated section. This is not appropriate. Only testing performed with and without the optional components could be accepted by the Commission for filing under a single FCC ID, or filing as a fully populated device only. 5.) The SAR report in Section 2.1 references an RF Pout of 87.09mW, but later in Section 3 references 30.7mW. Which is correct? Please review and correct as needed. In the SAR report, I am concerned with the interference of the lid in Mode 1. Please demonstrate this is the worst case position. In other words, please provide evidence that Mode 1 with the LCD lid of notebook computer perpendicular to phantom is not worst case relative to LCD lid parallel to phantom. 7.) Although listed elsewhere in the SAR report, it would be helpful to identify the test platform by make and 6.) model on each Mode photograph. 8.) The Mode Two plots in the SAR report appear strange especially when using the scale supplied on the right hand side of each plot. Are you showing the highest SAR occurred in fields around the EUT, and not centered on the EUT? Please confirm. 9.) The Test Setup photos are difficult to use. Can you please supply a close up showing where the EUT was positioned in the setup?

10.) The Test Report does not provide any graphical presentations (plots) for any of the 15.247 parameters. This will not be acceptable. Please review and supply at minimum Occupied Bandwidth, Spectral Power Density, Band Edge (preferably both radiated and conducted), and 6dB Bandwidth. A plot of the Powerline Conducted Emissions 15.207 is also preferred. 11.) Please show how label identified in Appendix 9 of Test Report will be affixed to EUT. This does not seem to match the Label information provided in the Label and Location exhibit to AmericanTCB. William H. Graff President and Examining Engineer mailto: whgraff@AmericanTCB.com 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. l Page 2 February 2, 2003 Please do not respond to this correspondence using the email reply button.

Note that the SSID will be case sensitivity. u Channel is not active in Infrastructure Mode. u Profiles allows you to save five sets of default settings. After entering the values of the settings (SSID, Network Type, Channel etc.), set a name in the Profiles field. Click Apply button. 23 3.5 Basic Setting for 802.11Ad Hoc Mode/Ad Hoc Mode If you have more computers and only want to place them in a local area network, or you want to communicate directly without using an Access Point or any connection to a wired network, then you can select the 802.11 Ad Hoc mode or Ad Hoc mode on your WLAN Utility. 802.11 Ad Hoc is the official standard set by IEEE Organization whereas Ad Hoc is a pre-standard. Therefore we recommend you to select the 802.11 Ad Hoc mode. Please note that 802.11 Ad Hoc mode and Ad Hoc mode are not compatible. If you select the 802.11 Ad Hoc mode, then all computers of your workgroup should be set as the 802.11 Ad Hocvice versa with the Ad Hoc mode. A. 802.11 Ad Hoc Please follow the procedures below to set the 802.11 Ad Hoc:

You may refer to the following 3 examples of Surveying the Network Neighborhood, File Sharing and Using the Shared Folder. 5.1 Surveying the Network Neighborhood When multiple base stations are up and running in your wireless network, you can use the procedure described below to display the other computers:

1. Double-click My Network Places to display all stations in your Microsoft Windows Network Group. 2. To display other workgroups in the network environment, double-click Entire Network. 3. If there is a second network operating system running in your network environment (for example a Novell NetWare network), the Entire Network window will also display available servers running under the second network operating system. If you click on these servers, you may be asked to enter your user name and password that applies to the other network operating system. If you cannot find it, verify whether the other wireless computers are:

l Powered up and logged on to the network. l Configured to operate with identical Microsoft Network settings concerning:

n Networking Protocol. n Wireless Network Name. To enable the sharing of Internet access, you should set your IEEE802.11b WLAN mode as Infrastructure and connect to the access point. 34 5.2 File Sharing 802.11b WLAN USB Adapter allows the sharing of files between computers that are logged onto the same wireless network. If you want to share your folder My Documents with other computers of the wireless network, please highlight the folder My Documents and drag it to Shared Documents folder. Sharing files in the IEEE802.11b wireless network will be like sharing files on a wired LAN. 35 5.3 Using the Shared Folder If you would like to access a shared folder stored in other stations of same network, please follow the process below:

1. Double-click the My Network Places icon, and then double-click the computer where the shared folder is located. 2. Double-click the folder you want to connect to. 3. Now you may open the needed file(s). Note! If a password is required, the Windows will prompt a password column to you. Then you need to enter the password that had been assigned to this shared folder. 36 6.
