Before Using the Wireless LAN

This manual describes the procedures required to prop-
erly setup 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
following device.
Intel PRO/Wireless M3B2915ABG Network Connec-
■
tions (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,
■
therefore eliminating the need to procure an FCC
license to operate. The WLAN device 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.
The Intel PRO/Wireless M3B2915ABG WLAN 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 maximum communication range indoors is
■
approximately 80 feet (25 meters). However, that

range will increase or decrease depending on factors
such as number of walls, reflective material, or inter-
ference from external RF sources.
The WLAN device supports the following encryption
■
methods - WEP, TKIP, and AES encryption.

WIRELESS LAN MODES USING THIS DEVICE

Ad Hoc Mode
(See Figure 5-1)
"Ad Hoc Mode" refers to a wireless network architecture
where wireless network connectivity 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
also known as peer-to-peer networks. Ad Hoc networks
are an easy and inexpensive method for establishing
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.
