Introduction The Wireless LAN network offers performance comparable to Ethernet networks,
but without the restraints of network cables. The Wireless LAN product family
includes the model WL-305 PC Card, the WL-307 USB Device, and the WL-308
PCI Card described in this manual.
Features Wireless LAN adapters use IEEE 802.11HR direct-sequence-based technology to
extend the range and versatility of a network. They provide a high-capacity link
across multiple access points within large or small indoor environments. Wireless
LAN product-family features include:
■
Bridging architecture allows communication between wired network devices
and mobile devices.
■
Compliance with IEEE 802.11 HR specification. This open architecture allows
Wireless LAN devices to communicate with wireless devices from other
manufacturers.
■ Extended roaming allows mobile devices to roam throughout large facilities
while remaining connected to the LAN.
Wireless LAN PC and PCI Card operating features include:
■
Support for standard NDIS (Network Driver Interface Specification) and drivers.
■
Support for Wndows 2000, Windows 98, Windows 95B, and Windows NT 4.0
(with Service Pack 3.0 or greater).
■
Plug and Play support.
■ Power management.
■
Low-power operation for battery-powered devices with PC Card slots.
Wireless LAN adapters support a maximum data rate of 11 Mbps. (The data rate
drops back to 5.5, 2, or 1 Mbps when the adapter cannot establish or maintain an
11 Mbps association.) Factors that can affect the data rate include:
■
A separation or change in signal strength between the Access Point and the
wireless client
■
The ratio of packets transmitted to transmissions attempted falling below a
preset threshold
■
The wireless client finding and switching to another Access Point with a higher
transmit rate
