Before Using the W ireless LAN
T he Integrated Wireless LAN is an optional device avail-
able for Fujitsu mobile computers. T his manual
describes the basic operating procedures for the Wireless
LAN (referred to as the "device" in this manual) and
how to set up a wireless LAN network. Before using this
device, read this manual carefully to ensure correct oper-
ation of the device. Keep this manual in a safe place for
reference while using the device.
Types of W ireless LANs Covered by this Document
T his 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 PROSet Wireless LAN(WM3B2200BG/
WM3B2915ABG)
Atheros Wireless LAN(WLL4030/WLL3050)
If your system is a Stylistic S7010, your wireless module
is the Intel PROSet wireless LAN; if your system is a
Stylistic S7010D, your wireless module is the Atheros
wireless LAN;
Characteristics of the Device
T his device consists of a wireless LAN card that is
attached inside the computer via a mini-PCI slot.
T he main characteristics are as follows:
It operates in the 2.4 GH z Industrial, Scientific, and
Medical (ISM) RF band; additionally, the Atheros
wireless LAN operates in the 5 GH z 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.

T his wireless module is Wi-Fi compliant. T he module
can communicate at a maximum data rate of 54 Mbps.
T he 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 upon factors such as
obstructions, walls, columns, construction material,
and reflective objects.
T he wireless module s support a number of industry-
standard security mechanisms, including WEP, T K IP,
and 802.1x/EAP (LEAP, T LS, PEAP, MD5).
W ireless LAN Modes Using this Devic e
Ad Hoc Mode (See Figure 1)
"Ad Hoc Mode" 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
computers.
In the Ad Hoc mode, you can use the function
supported by Microsoft Network, such as File and Print
Sharing to exchange files and share a printer or other
peripheral devices.
To use Ad Hoc Mode, you must set the same SSID 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.
