The WM821-
M is a dual-band, quad-mode wireless network adapter that works on all the frequencies allocated for WLAN operation eve-
rywhere in the world. It is in compliance with the Draft IEEE802.11n standard in a 2x3 MIMO configuration. It also complies with the IEEE 802.11a, 802.11g, and 802.11b stan-
dards. WM821-M features the compactness and high bus speed of the Mini PCI specifications which gives users of lap-
tops, notebooks, tablet PCs, and other mobile computing devices transparent Internet access anywhere in the world through any Wi Fi network without software changes or addi-
tional hardware. Able to provide greater than 100Mbps real world throughput using high-speed spatial multiplexing modes, the WM821-M provides the freedom to work as you wish, wherever you wish, using whatever kind of application you wish to use. The adapter installs directly in any host device with a Mini PCI slot: just plug it in and youre ready to access local resources and/or the Inter-
net at the highest speed the WLAN, the location, and the host computer can provide. It is ready to work out of the box in any embedded device or in any computer running Microsoft Win-
dows 2000, or XP (TBD). The WM821-M Mini PCI Card is truly a must-have for every productivity-sensitive laptop, notebook, 1 WM821-M MiniPCI Module Introduction or tablet PC user and any bandwidth-sensitive embedded de-

Wireless Local Area Network (WLAN) systems offer a great number of advantages over traditional wired systems. WLANs are flexible and easy to setup and manage. They are also more economical than wired LAN systems. Using radio frequency (RF) technology, WLANs transmit and receive data through the air. WLANs combine data connectivity with user mobility. For example, users can roam from a confer-
ence room to their office without being disconnected from the LAN. Using WLANs, users can conveniently access shared informa-
tion, and network administrators can configure and augment networks without installing or moving network cables. WLAN technology provides users with many convenient and cost saving features:
Mobility: WLANs provide LAN users with access to real-
time information anywhere in their organization, providing service opportunities that are impossible with wired net-
works. Ease of Installation: Installing is easy for novice and ex-
pert users alike, eliminating the need to install network cables in walls and ceilings. Scalability: WLANs can be configured in a variety of to-
pologies to adapt to specific applications and installations. Configurations are easily changed and range from peer-
to-peer networks suitable for a small number of users to 3 WM821-M MiniPCI Module Introduction full infrastructure networks of thousands of users roaming over a broad area. 4 Chapter 2 Hardware installation This chapter covers how to installing the Wireless MiniPCI Module in your embedded system. Hardware description The Wireless MiniPCI Module has a standard MiniPCI inter-
face for attaching to the MiniPCI connector on embedded system. And this module has IPEX connector to connect to external antenna. Outlook Following is the MiniPCI module outlook 5 WM821-M MiniPCI Module Hardware installation Figure 1: MiniPCI module outlook 6 Chapter 3 Using the Wireless Utility This module also come with a wireless utility, following describe how to use the utility. Configuration Utility The Client Card Configuration Utility allows configuration of WM821-M high throughput client cards through the following tabs:
Network Statusdisplays the status of the network to which the user is connected. The Configuration Utility initializes on this page. Profile Managerdisplays the current profiles and allows the user to set attributes for network type, security options, and protocols, as well as create/modify/delete profiles.

When the Wireless client card Configuration Utility initializes, it displays the Network Status tab. 7 WM821-M MiniPCI Module Using the Wireless Utility Figure 2 :Network Status tab 3.1.1 Select Profile The Select Profile section displays the name of the profile in use. Additional infor-
mation about the profile is provided in the Profile Manager. Select one of the profiles previously defined by clicking the down arrow and high-
lighting a profile from the pull-down list. Figure 3: Select Profile Section 8 Appendix B Error Messages of Enabler Program Figure 3: Select Profile Profiles are created, modified, and deleted through the ProfileMan-

Scanning for Scanning for available APs and wireless sta-
tions in the area. Network SSID label (i.e., Network Name). The Network Name is a text string of up to 32 characters. Type of environment connected to: Infrastructure Mode In this mode, wireless clients send and receive information through APs. When a wireless client communicates with an-
other, it transmits to the AP. First the AP receives the information and rebroadcasts it, then other devices receive the information. The APs are strategically located within an area to provide optimal coverage for wireless clients. A large WLAN uses multiple APs to provide coverage over a wide area. APs can connect to a LAN through a wired Ethernet connection. APs send and receive information from the LAN through the wired connection. 10 Network BSSID Security Appendix B Error Messages of Enabler Program Network Basic Service Set Identifier.

. 3.1.4 Internet Protocol (TCP/IP) The Internet Protocol specifies the format of packets, also called data grams, and the addressing scheme. Most networks combine IP with a higher-level protocol called TCP, which establishes a virtual connection between a destination and a source.

The format of an IP address is a 32-bit numeric address written as four numbers separated by periods. Each number can be 0 to 255. A mask used to determine what subnet an IP address belongs to. An IP address has two components, the network address and the host address. The first two numbers represent the Class B network address, and the second two numbers identify a particular host on this network. The default node on a network that serves as an entrance to another network. In enterprises, the gateway is the computer that routes the traffic from a workstation to the outside network that is serving the Web pages. In homes, the gateway is the ISP that connects the user to the Internet. 3.1.5 Actual Throughput Performance This section of the Network Status tab displays the Current Tx Rate and the Cur-
