2-1 SD-Link11b features and benefits

SD-Link11b Manual Introducing SD-Link11b Card

The SD-Link11b enables you to:
- Connect your computer to a Peer-to-Peer workgroup of wire-
less computing devices
- Connect your computer to a Small Office/Home Office (SOHO)
network that includes Wi-Fi access points.
- Connect your computer to a Local Area Network (LAN) Infra-
structure that includes the SD-Link11b, or other IEEE 802.11b
compliant LAN systems
Wireless stations can be equipped with the SD-Link11b, but also
with other WLAN PC Cards. Both the SD-Link11b and the WLAN PC
Card share the same wireless functionality.
2-2-1 Peer-to-Peer (Ad-hoc) Workgroup
The Peer-to-Peer workgroup con-
figuration enables you to quickly
set up a small wireless work-
group, where the workgroup par-
ticipants can exchange files using
features like “Files and Printer
Sharing” as supported by
Microsoft®Networking.
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.
