Types of W ireless LANs Covered by this Document
This document is applicable to systems containing one
of the following two wireless modules. Most of the
procedures are identical. Sections that differ between the
two devices have been noted in the text:

Intel PROSet Wireless LAN

Atheros Wireless LAN
If your system is a T3010 model, your wireless module
Characteristics of the W ireless M odule
This wireless module is a mini-PCI card attached to a
mini-PCI slot inside the computer.
The main characteristics are as follows:

It operates in the 2.4 GH z Industrial, Scientific, and
M edical (ISM ) RF band; additionally, the Atheros
wireless LAN operates in the 5 GHz RF band.

It does not require an FCC license to operate.

It uses Direct Sequence Spread Spectrum (DSSS), an
RF modulation scheme that is resistant to noise.

This wireless module is Wi-Fi compliant. The Intel
PROSet module can communicate at a maximum data
rate of 11 M bps; the Atheros module can communi-
cate at the maximum data rate of 54 M bps.

The maximum communication range is approxi-
mately 80 feet (25 meters) inside a building. Please
note that the range you achieve may be shorter or
longer than 80 feet, depending on factors such as
obstructions, walls, columns, construction material,
and reflective objects.

The wireless modules support a number of industr y-
standard security mechanisms, including WEP, TKI P,
and 802.1x/EAP (LEAP, TLS, PEAP, M D5).

Ad Hoc M ode (See Figure A-1)
“Ad Hoc M ode” refers to a type of wireless network that
involves connecting multiple computers without the use
of an Access Point. Network connectivity between
computers can be established using only wireless LAN
cards in a peer-to-peer fashion.
Ad Hoc networks are an easy and inexpensive method
for establishing network connectivity between multiple
com puters.
In Ad Hoc mode, you can use M icrosoft Network func-
tions, such as File and Print Sharing to share folders,
printers, or other peripheral devices, and exchange files
with other computers.
To use Ad Hoc M ode, you must set the same SSI D and
the same encryption key for all the computers that are
connected. Communication between computers in an
Ad Hoc network will occur provided they are within
each other’s RF coverage area.

describes the basic operating prodecures for the
Wireless LAN (referred to as the "wireless module" in
this manual) and how to set up a wireless LAN network.
Before using this wireless module, read this manual
carefully to ensure correct operation of the device. Keep
this manual in a safe place for reference while using the
wireless module.
