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 one
of the following two devices. Most of the procedures are
identical. Sections that differ between the two devices
have been noted in the text:
Intel PRO/Wireless 2200BG Network Connections
■
(802.11b/g)
Intel PRO/Wireless 2915ABG 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 devices operate in license-free RF bands,
■
therefore eliminating the need to procure an FCC
license to operate. Both WLAN devices operate in the
2.4GHz Industrial, Scientific, and Medical (ISM) RF
band. Additionally, the Intel PRO/Wireless 2915ABG
device operates in the lower, middle, and upper bands
of the 5GHz Unlicensed National Information Infra-
structure (UNII) bands.
The Intel PRO/Wireless 2200BG WLAN device is
■
capable of two operating modes, IEEE802.11b and
IEEE802.11g. The Intel PRO/Wireless 2915ABG
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 A-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.
