Wireless Interoperability
The Toshiba Wireless LAN Mini PCI Card products are designed to be interoperable with any
wireless LAN product that is based on Direct Sequence Spread Spectrum(DSSS) radio
technology, and is compliant to:
¦The IEEE 802.11 Standard on Wireless LANs(Revision B), as defined and approved by the
Institute of Electrical and Electronics Engineers.
¦The Wireless Fidelity(WiFi) certification as defined by the WECA Wireless Ethernet
Compatibility Alliance.
Wireless LAN and your Health
Wireless LAN products, like other radio devices, emit radio frequency electromagnetic
energy. The level of energy emitted by Wireless LAN devices however is far much less than
the electromagnetic energy emitted by wireless devices like for example mobile phones.
Because Wireless LAN products operate within the guidelines found in radio frequency
safety standards and recommendations, Toshiba believes Wireless LAN is safe for use by
consumers. These standards and recommendations reflect the consensus of the scientific
community and result from deliberations of panels and committees of scientists who
continually review and interpret the extensive research literature.
In some situations or environments, the use of Wireless LAN may be restricted by the
proprietor of the building or responsible representatives of the organization. These
situations may for example include:
¦ Using the Wireless LAN equipment on board of airplanes, or
¦ In any other environment where the risk of interference to other devices or services is
perceived or identified as harmful.
If you are uncertain of the policy that applies on the use of wireless devices in a specific
organization or environment (e.g. airports), you are encouraged to ask for authorization to
use the Wireless LAN device prior to turning on the equipment.

Wireless LAN Network Scenarios
The Wireless LAN Card Kit enables you to:
n Connect your computer to a Peer-to-Peer workgroup of wireless computing devices.
n Connect your computer to a Local Area Network (LAN) Infrastructure that includes
Wireless LAN Access Points, or other IEEE802.11 compliant LAN systems.
n Expand the capabilities of your Wireless LAN Access Points, to support wireless
devices that have been equipped with Wireless LAN Card.
NOTE:
The internal Wireless LAN Card can’t be used with the “Toshiba Wireless LAN PC
Card”.

Peer-to-Peer Workgroup
The Peer-to-Peer workgroup configuration enables you to quickly set up a small wireless
workgroup, where the workgroup participants can exchange files using features like “Files
and Printer Sharing” as supported by Microsoft Networking.
Figure 1-1 Peer-to-Peer Wireless Workgroup
You can use this option to setup a temporary or ad-hoc network in environments where no
access points are available (for example in Small Office/Home Office (SOHO)
environments).
As long as the stations are within range of one another, this is the easiest and least
expensive way to set up a wireless network.

With the Wireless LAN Access Points you can connect to a corporate Local Area Network
(LAN) infrastructure to have wireless access to all network facilities. LAN Infrastructures

It’s Easy
The Wireless LAN Card functions like any standard wired Ethernet card, but Wireless LAN
does not need any wires!
Where an Ethernet card requires a cable connection to a hub and/or patch panel, the cable
physically ties you down to the location of the wired connection.
Wireless LAN allows you connect your computer to a Local Area Network (LAN) system
from anywhere within the wireless coverage area. Expanding or re-designing your network
is easy: Add or relocate Wireless LAN Access Points, power -up your (new) Wireless LAN
computers, and you’re done!
Unlike Ethernet, Wireless LAN will enable you to roam throughout the network while
remaining connected to the LAN.
NOTE:
The Wireless LAN Card is a radio product. Refer to the flyer “Information to the User” for
regulatory information that may apply in your country.

Radio Characteristics
Radio Characteristics of Wireless LAN Cards may vary:
n According to the country where the product was purchased.
n According to the type of product that was purchased.
Wireless communication is often subject to local radio regulations. Although Wireless LAN
Wireless networking products have been designed for operation in the license-free 2.4GHz
band, local radio regulations may impose a number of limitations to the use of wireless
communication equipment.
NOTE:
Refer to the flyer “Information to the User” for regulatory information that may apply in
your country.

The range of the wireless signal is related to the Transmit Rate of the wireless
communication. Communications at lower Transmit range may travel larger distances.
NOTE:
The range values listed in Table A-4 are typical distance as measured at the Toshiba
Wireless LAN laboratories. These values may provide a rule of thumb and may vary
according to the actual radio conditions at the location where the Wireless LAN product
will be installed.
n The range of your wireless devices can be affected when the antennas are placed
near metal surfaces and solid high-density materials.
n Range is also impacted due to “obstacles” in the signal path of the radio that may
either absorb or reflect the radio signal.
Table A-4 lists the typical ranges when used indoors in “office environments” that can be
described as follows:
n In Open Office environments, antennas can “see” each other, i.e. there are no
physical obstructions between them.
n In Semi-open Office environments, work space is divided by shoulder-height, hollow
wall elements; antennas are at desktop level.
n In Closed Office environments, work space is separated by floor-to-ceiling brick
walls.

Supported Frequency Sub-bands
Subject to the radio regulations that apply in your country, your Wireless LAN Card may
support a different set of 2.4 GHz channels (see Table A-5).

When installing Wireless LAN Cards the channel configuration is managed as follows:
n For wireless clients that operate in a Wireless LAN Infrastructure, the Wireless LAN
Card will automatically start operation at the channel identified by the Wireless LAN
Access Point, When roaming between different access points the station can
dynamically switch to another channel if required.
n For Wireless LAN Cards installed into wireless clients that operate in an “Peer-to-Peer”
mode, the card will use the default channel 10.
n When inserted into a Wireless LAN Access Point, the Wireless LAN Card will use the
factory-set default channel (printed in bold), unless the LAN Administrator selected a
different channel when configuring the Wireless LAN Access Point device.
