Information to the User
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 inter nal 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 fil es 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.

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 anywh ere 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.

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.

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.
