Psion Teklogix 9160 G2 Wireless Gateway User Manual 203
The 9160 G2 Wireless Gateway lets you connect multiple access points using a Wireless
Distribution System (
WDS ). WDS allows access points to communicate with one another
wirelessly. This capability is critical in providing a seamless experience for roaming clients
and for managing multiple wireless networks. It can also simplify the network infrastructure
by reducing the amount of cabling required.
The following sections describe how to configure the WDS on the 9160 G2 Wireless
Gateway.
20.1 Understanding The Wireless Distribution System
A Wireless Distribution System ( WDS ) is a technology that wirelessly connects access
points, known as Basic Service Sets ( BSS ), to form what is known as an Extended Service
Set ( ESS ).
Note: A BSS generally equates to an access point (deployed as a single-AP wireless “net-
work”), except in cases where multi-BSSID features make a single access point look
like two or more access points to the network. In such cases, the access point has mul-
tiple unique BSSIDs.
20.1.1 Using WDS To Bridge Distant Wired LANs
In an ESS , a network of multiple access points, each access point serves part of an area
which is too large for a single access point to cover. You can use WDS to bridge distant Eth-
ernets to create a single
LAN . For example, suppose you have one access point which is
connected to the network by Ethernet and serving multiple client stations in the Conference
Room (LAN Segment 1), and another Ethernet-wired access point serving stations in the
West Wing offices (LAN Segment 2). You can bridge the Conference Room and West Wing
access points with a WDS link to create a single network for clients in both areas (see
Figure 20.1 on page 204).
