1.6 Wireless Operation Modes
The VH-4GW can perform as a multi-function wireless device. Users can easily
select which wireless mode they wish the VH-4GW to perform.
The VH-4GW can be configured to operate in the following wireless operation
modes:
1.6.1 WDS Bridge Mode
This mode is also known as “WDS Pure MAC mode”. When configured to operate in
the Wireless Distribution System (WDS) Mode, the VH-4GW provides bridging
functions with remote LAN networks in the WDS system. The system will support up
to total of 8 bridges in a WDS network (by daisy chain). However, each bridge can
only associate with maximum of 4 other bridges in the WDS configuration. This
mode is best used when you want to connect LAN networks together wirelessly (for
example, between office and warehouse). If you have more than 2 AP in WDS
Bridges mode, please remember to avoid duple connection to one device, otherwise
the network loop can be occurred. This mode usually delivers faster performance
than infrastructure mode.
