RoamAbout PC Card
The RoamAbout PC Card is an IEEE 802.11 Direct Sequence (DS) compliant wireless
network interface card.
The RoamAbout PC Card functions like any standard wired Ethernet card; however, the
RoamAbout PC Card uses radio frequencies instead of a cable for the LAN connection.
When installed in a computer, the PC Card and computer are referred to as a RoamAbout
wireless client.
The RoamAbout PC Card fits into any PC card type II slot and includes the following
features:
•
The ability to support desktop PCs, via one of the following adapters:
— RoamAbout ISA Adapter Card option, which allows installation into computers
that do not have a PC card slot but do have an available ISA bus slot.
— RoamAbout PCI Adapter Card option, which allows installation into computers
that do not have a PC Card slot or an ISA bus slot. The PCI Adapter works with
Microsoft Windows PC99-compliant PCs (PCI-slot-only PCs) that have
BIOS-supported PCI 2.2 or higher.
•
An 802.11 DS compliant radio.
•
The ability to communicate with 802.11 DS compliant APs or other 802.11 clients.
•
The RoamAbout Client Utility, which allows you to monitor the quality of wireless
communication.
•
Support for Windows 95, Windows 98, Windows NT, Windows 2000, Windows Me,
Windows XP, MS-DOS, Windows 3.x, Windows CE, Linux, and Apple PowerBook
computers. Refer to the RoamAbout 802.11 PC Card Drivers and Utilities Setup and
Installation Guide for more information.
•
802.11 power management.
•
Wired Equivalent Privacy (WEP) security.
•
Roaming, where the client can move from one AP to another in the same wireless
network without losing LAN connectivity.
•
Roaming over multiple channels. The RoamAbout PC Card automatically uses the
same channel as the associated AP.
•
The RoamAbout PC Card is also the means by which a RoamAbout AP communicates
with a wireless network. This manual considers an AP and its installed PC Card(s) as
one unit.
