Toshiba Wireless LAN mini-PCI Card – Getting started About Toshiba Wireless Solution 1 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”.
Toshiba Wireless LAN mini-PCI Card – Getting started 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.
Toshiba Wireless LAN mini-PCI Card – Getting started Enterprise Networking Figure 1-2 Stand Alone Wireless LAN 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 may either be. n Stand-alone wireless LANs as pictures in Figure 1-2 n Wireless network infrastructures connected to an existing Ethernet network as pictured in Figure 1-3.
Toshiba Wireless LAN mini-PCI Card – Getting started Figure 1-3 LAN Infrastructure
Toshiba Wireless LAN mini-PCI Card – Getting started 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.

Toshiba Wireless LAN mini-PCI Card – Getting started 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.
Toshiba Wireless LAN mini-PCI Card – Getting started 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).
