Before Using the Wireless LAN

This manual describes the procedures required to prop-

erly set up and configure the integrated Wireless LAN

Mini-PCI device (referred to as "WLAN device" in the

rest of the manual). Before using the WLAN device, read

this manual carefully to ensure it's correct operation.

Keep this manual in a safe place for future reference.

Wireless LAN Device Covered by this Document

This document is applicable to systems containing the

Intel PRO/Wireless 3945ABG (WM3945ABG) Network

Connections (802.11a+b/g)

Characteristics of the WLAN Device

■

The WLAN device is a Mini-PCI card attached to the

main board of the mobile computer.

■

The WLAN device operates in license-free RF bands,

eliminating the need to procure an FCC operating

license. The WLAN operates in the 2.4GHz Industrial,

Scientific, and Medical (ISM) RF band and the lower,

middle, and upper bands of the 5GHz Unlicensed

National Information Infrastructure (UNII) bands.

■

This wireless device is capable of three operating

modes, IEEE802.11a, IEEE802.11b and IEEE802.11g.

■

The WLAN device is Wi-Fi certified and operates at

the maximum data transfer rate of 54 Mbps in

IEEE802.11a or IEEE802.11g mode and 11 Mbps in

IEEE802.11b mode.

■

The WLAN device supports the following encryption

methods - WEP, TKIP, CKIP, and AES encryption.

■

This device is compliant with the following standards:

WPA, WPA2, CCX1.0, CCX2.0, and CCX3.0.

WIRELESS LAN MODES

Ad Hoc Mode

(See Figure A-1) "Ad Hoc Mode" refers to a wireless

network architecture where wireless network connec-

tivity between multiple computers is established without

a central wireless network device, typically known as

Access Point(s). Connectivity is accomplished using only

client devices in a peer-to-peer fashion. That is why Ad

Hoc networks are known as peer-to-peer networks. Ad

Hoc networks are an easy, inexpensive method to estab-

lish network connectivity between multiple computers.

Ad Hoc mode requires that the SSID, network authenti-

cation, and encryption key settings are identically

configured on all computers in the Ad Hoc network.

Access Point (Infrastructure) Mode

(See Figure A-2) Infrastructure mode refers to a wireless

network architecture in which devices communicate

with wireless or wired network devices by communi-

cating through an Access Point. In infrastructure mode,

wireless devices can communicate with each other or

with a wired network. Corporate wireless networks

operate in infrastructure mode because they require

access to the WLAN in order to access services, devices,

and computers (e.g., file servers, printers, databases).

How to Handle This Device

The WLAN device comes pre-installed in your mobile

computer. Under normal circumstances, it should not be

necessary for you to remove or re-install it. The Oper-

ating System that your mobile computer comes with has

been pre-configured to support the WLAN device.

The Intel PRO/Wireless 3945ABG WLAN device sup-

ports IEEE802.11a, IEEE802.11b and IEEE802.11g.
