Warranty Card Planning your Wireless LAN There are two usage modes for Wireless LAN, Ad-hoc mode and Infrastructure mode. Please review your need and build your Wireless LAN. Ad-hoc Networking Ad-hoc network also is called Peer-to-Peer network. Without Access Point, notebook users with WLAN MiniPCI Card can build Ad-hoc Peer-to-Peer wireless networks to share files with each other, share a public office printer and other peripheral resources, even access the Internet via a modem. Infrastructure Networking 802.11b-compatible Access Point is a bridge or routers connecting to the wired Ethernet network and wireless network. Through the deployment of Access Point, wireless LAN can be extended to the reach of a wired network. Therefore, a notebook user with WLAN MiniPCI Card can access to fixed local network resources. - 3 - Installation Installation for Windows 95, Windows 98 and Windows 2000 Before installing the driver, you will need a copy of the operating system installation media, usually a CD supplied with your computer or operating system. On Windows 98 systems, the installation files are sometimes archived on the hard disk in C:\WINDOWS\OPTIONS\CABS. On Windows 2000 systems, the system may prompt you to load operating system files from the Windows 2000 installation disk. Installation under Windows 95 is identical to the procedure given above for Windows 98 and Windows 2000. Only Windows 95 OSR2 or higher is supported. The Setup program also installs Configuration Utility in the WLAN MiniPCI Card in the Program directory. This configuration utility can help you to understand and maintain your Wireless LAN. Install Driver Step 1: Insert the WLAN MiniPCI Card into the MiniPCI socket of Notebook. Step 2:. Turn on your computer. Step 3: Windows finds a new hardware shown WLAN MiniPCI and asks for the driver of WLAN MiniPCI Card. The driver installation wizard guides you through the steps standard for your operating system. Step 4: You will be asked to supply CDs or directory path information for the driver. This driver shall be located in the following directory. D:\ (if D:\ is your CD-ROM drive) Step 5: Windows finds the driver described as WLAN MiniPCI Card. Follow the directions of Windows dialog boxes to complete the driver installation. After completing the installation, Windows dialog will display Systems Setting Change and ask to restart the notebook. Click “Yes” to reboot the computer. Install Configuration Utility 1. Restart the computer and ensure ireless LAN Configuration Utility CD in the CD-ROM drive. - 4 - You can run the program manually by selecting Run from the Start menu and running SETUP.EXE from the CD-ROM drive. D:\ SETUP.EXE (if D:\ is your CD-ROM drive) 2. On the WLAN MiniPCI Card– Installation screen, click next to start software installation. Read the information in the Welcome dialog box and click “Next”. Then, click ““Yes”” if you accept the Software License Agreement. 3. Enter the name of the Wireless LAN Service Set of the wireless network (SSID) to which your computer will connect. The name you enter here must match exactly the name assigned to the access point. Characters, capitalization, and spacing must be identical. NOTE: If the access point you wish to associate with has encryption active, you must also enable encryption on the wireless client. Click Encryption in the Configuration Utilities after reboot to go to screens where you can enable and configure encryption. You must set the wireless client for the same Encryption algorithm and Key values as the access point it will associate. Refer to the Advanced Configuration section for more details about configuring encryption 4. Select which network mode is suitable for your Wireless LAN. Infrastructure Mode is default selection. This setting can be changed at any time after installation completion. 5. Accept the default program folder or select where the SETUP.exe stores the Configuration Utility. 6. Select ““Yes”, I want to restart my computer now”. Reboot your computer by clicking Finish. LED Indication The yellow LED of Wireless LAN MiniPCI Card performs identical functions when indicating the operational status of the card. Advanced Configuration - 5 - Configuration Mode (Network Mode) 1. Ad-Hoc: The Ad-Hoc network is also known as a peer-to-peer network. An Ad-Hoc networking does not need Access Point. Instead, the Ad-Hoc network is a loose association of wireless computers that can communicate with each other using Wireless LAN MiniPCI Card in Ad-Hoc Mode 2. Infrastructure: In a wireless infrastructure network, wireless stations communicate with an Access Point to connect to a wired network. An infrastructure network also can consist of multiple Access Points. This can extend the coverage area of wireless network. In this configuration, the wireless network consists of cells. Each cell is a single Access Point that has different frequency channel to prevent from interfering each other. A wireless station can move from one Access Point to next without losing the network connection. SSID The SSID is the name of wireless network for Ad-Hoc or Infrastructure mode. To add a Wireless LAN MiniPCI Card to an existing wireless network, configure SSID to match the name of the wireless network Tx Rate The Fixed 1, 2, 5.5, 11Mb/s or Fully Auto transmit rates can be selected for Wireless LAN Card. Basically, the Fully Auto setting allows the MiniPCI Card to automatically switch t…

To: [email protected] Subject: Review of D-Link Corporation., FCC ID: KA22001120018-1 Dear Tim For Q1. This module will be sold to the integrators only, not for the end users. And for Q2&3, we've adjusted the file Modular request letter and Operation Description, this device will only be installed in AP and Router. Emily

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 June 20, 2002 RE: D-LINK CORPORATION FCC ID: KA22001120018-1 After a review of the submitted information, I have a few comments on the above referenced Application. 1) Please explain how this device will be limited to a mobile device (i.e. to 20 cm distance) when a modular application is requested and D-Link Corporation does not necessarily maintain control over its final use. Explanation of this may include explaining that the device is only sold directly to integrators who have been given specific instructions, or that is is for use only within D-Link specific products that will be able to maintain the 20 cm mobile, or any other special hardware and/or software limitation designed into the device. 2) Modular approval is requested on this device with a limitation to mobile classification. Access points, routers, etc. are self explanatory, but there is also mention of laptop configurations. The users manual should provide more detail to the integrator regarding this type of configuration. It is recommended that the following (or similar language) be added to the Manual: SPECIAL NOTE TO NOTEBOOK OEM INTEGRATORS: The FCC has specified strict co-location and antenna to user distances that must be followed to keep this product in compliance with the FCC's regulations. The transmit antenna must be installed in such a way that the distance between a user and the antenna is greater than 20 cm during normal use of the laptop (neglecting the hands and wrists). Special concern must be given to the placement of the antennas if the user is able to use the notebook in their lap. In general, installation of the transmit antenna in a typical notebook will likely need to be along the upper portion of the LCD display area in order to meet the 20 cm limitation of this device. Any other installation of the antenna and the FCC authorization of this device is no longer considered valid and the FCC ID: KA22001120018-1 may NOT be used on the final product. Additionally, the notebook should not contain any other RF transmitters. If the final OEM product can not meet the 20 cm requirement or the final product contains an additional RF transmitter, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. 3) The length of cable to the antenna does not appear to be long enough to allow installation of the antenna in laptop configurations. Please explain for laptop configurations how D-Link plans to maintain the proper connector + cable + antennas as specified in this application. 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. z Page 2June 20, 2002 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.

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: KA22001120018-1 ADT No.: 910602R01 RF Exposure Measurement (Mobile 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. Classification The antenna of the product, under normal use condition, is at least 20 cm away from the body of the user. Warning statement for keeping 20 cm separation distance and the prohibition of operating next to a person has been printed on the users 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: KA22001120018-1 ADT No.: 910602R01 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: KA22001120018-1 ADT No.: 910602R01 6. Test Results 6.1 Antenna Gain The maximum Gain measured in Fully Anechoic Chamber is 5dBi or 3.16 (numeric). 6.2 Output Power Into Antenna & RF Exposure Distance : CHANNEL CHANNEL FREQUENCY (MHz) OUTPUT POWER TO ANTENNA (mW) MINIMUM ALLOWABLE DISTANCE ( r ) FROM SKIN (Centi-Meter) 1241229.382.72 6243730.342.76 11246230.412.77 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.
