Introduction

Thank you for using the Wireless MiniCard. The MM200-M is a single-band, quad-mode wireless net­work adapter that works on all the frequencies allocated for WLAN operation everywhere in the world. It
is in compliance with the IEEE802.11g, 802.11b standards. MM200-M features the compactness and
high bus speed of the Minicard specifications which gives users of laptops, notebooks, tablet PCs, and
other mobile computing devices transparent Internet access anywhere in the world through any WiFi
network without software changes or additional hardware.

Able to provide greater than 54Mbps real world throughput using high-speed spatial multiplexing
modes, the MM200-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 you’re ready to access local resources and/or the Internet 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® Windows Vista, or XP. The MM200-M MiniCard is truly a
“must-have” for every productivity-sensitive laptop, notebook, or tablet PC user and any bandwidth­sensitive embedded design.

What is Wireless LAN?

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 conference room to their
office without being disconnected from the LAN.

Using WLANs, users can conveniently access shared information, 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 organi-
zation, providing service opportunities that are impossible with wired networks.

• Ease of Installation: Installing is easy for novice and expert users alike, eliminating the need to
install network cables in walls and ceilings.

• Scalability: WLANs can be configured in a variety of topologies 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 full infrastructure networks of thousands of users roaming over a
broad area.

LAN Modes

Wireless LANs can be configured in one of two ways:

Ad-hoc
Networking

Infrastructure
Networking

Also known as a peer-to-peer network, an ad-hoc net­work is one that allows all workstations and computers
in the network to act as servers to all other users on the
network. Users on the network can share files, print to
a shared printer, and access the Internet with a shared
modem. However, with ad-hoc networking, users can
only communicate with other wireless LAN computers
that are in the wireless LAN workgroup, and are within
range.

Infrastructure networking differs from ad-hoc network­ing in that it includes an access point. Unlike the ad­hoc structure where users on the LAN contend the
shared bandwidth, on an infrastructure network the
access point can manage the bandwidth to maximize
bandwidth utilization.

Additionally, the access point enables users on a wire­less LAN to access an existing wired network, allowing
wireless users to take advantage of the wired networks
resources, such as Internet, email, file transfer, and
printer sharing.

Infrastructure networking has the following advantages
over ad-hoc networking:

• Extended range: each wireless LAN computer

• Roaming: the access point enables a wireless

• Wired to wireless LAN connectivity: the access

point bridges the gap between wireless LANs and
their wired counterparts.

Notes on wireless LAN configuration

When configuring a wireless LAN (WLAN), be sure to note the following points:

• Optimize the performance of the WLAN by ensuring that the distance between access points is not
too far. In most buildings, WLAN cards operate within a range of 100 ~ 300 feet, depending on the
thickness and structure of the walls.

• Radio waves can pass through walls and glass but not metal. If there is interference in transmitting
through a wall, it may be that the wall has reinforcing metal in its structure. Install another access
point to circumvent this problem.

• Floors usually have metal girders and metal reinforcing struts that interfere with WLAN transmis­sion.

Using the Wireless Utility

This module also come with a wireless utility, following describe how to use the utility.

Configuration Utility for 802.11b/g

The Client Card Configuration Utility allows configuration of MM200-M high throughput client cards
through the following tabs:

•Network Status—displays the status of the network to which the user is connected. The Configura­tion Utility initializes on this page.

•Profile Manager—displays the current profiles and allows the user to set attributes for network type,
security options, and protocols, as well as create/modify/delete profiles.

•Site Survey—displays site survey information.

•Statistics—displays the statistics of the current session.

•Advanced—used to set protocol parameters.

•AutoLink—to set AutoLink connection

•Admin—used to import and export profiles.

•About—provides the information for the driver version number, firmware version number, Configura-

tion Utility version number, and Medium Access Controller (MAC) address of the client card.

3.1 Network Status Tab

The Network Status tab displays the status of the network. When the Wireless client card Configuration Util­ity initializes, it displays the Network Status tab.

Field Description

Network Type Type of environment connected to:

• Infrastructure Mode In this mode, wireless clients send and
receive information through APs. When a wireless client com­municates with another, 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.

• Ad-Hoc Mode In this mode, wireless clients send and receive

information to other wireless clients without using an AP. This
type of WLAN only contains wireless clients. Use Ad-Hoc mode
to connect network computers at home or in small office, or to
set up a temporary wireless network for a meeting.

Network BSSID Network Basic Service Set Identifier. The BSSID is a 48-bit

identity used to identify a particular BSS within an area. In Infra­structure BSS networks, the BSSID is the MAC

also through the Site

3.1.3 Signal Strength / Wireless Mode Indicator

Appendix B Error Messages of Enabler Program

The color-coded Signal Strength bar displays the signal strength of the last packet received by the client

card.

Figure 5: Signal Strength

Signal strength is reported as a percentage. A signal in the red indicates a bad connection. A signal in the
green indicates a good connection.
The Wireless Mode indicator shows the data rates the client card operates. There are two modes:
. • 802.11b
. • 802.11g (backward compatible to 802.11b)

3.1.4 Internet Protocol (TCP/IP)

The Internet Protocol specifies the format of packets, also called datagrams, 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.
