3.16 Repeater (WDS)
The range of a wireless network can be extended by allowing Access Points to behave as repeaters and forward traffic
to other Access Points. Access Point to Access Point communications is also known as Wireless Distribution System
(WDS). The XYR301-E offers very powerful WDS configuration, allowing for a
mesh network with self-healing
functionality. Alternatively, fixed AP to AP links can be configured for optimized throughput.
Each XYR301-E Access Point supports up to 10 separate
interfaces for WDS links to other devices.
Each WDS interface can be either a bridge or router interface (refer section 1.1 “Network Topology” for more
information on bridge vs router). If you need a simple repeater network, use a bridge interface.
A WDS
bridge interface allows traffic to be bridged to another Access Point on the same IP network. WDS bridge
interfaces do not require additional IP Address configuration, as they are bridged with the standard wireless interface
that is used for connections to associated clients. All of the WDS interfaces on the one Access Point may be bridged if
required.
WDS bridge interfaces have the advantage that redundant paths are permitted when using the bridge Spanning Tree
Protocol (see section 3.5 “Spanning Tree Algorithm / Redundancy”), thus behaving as a self-healing mesh network.
Bridged networks are also not as configuration intensive as routed networks. Since WDS bridge interfaces generally do
not require IP address configuration (they inherit the IP address of the standard wireless interface).
A WDS
router interface allows traffic to be routed to an Access Point on a different network, and therefore requires
configuration of an IP address to reflect the network address of the destination network. WDS router interfaces cannot
provide the redundancy of bridge interfaces, but can be used to reduce radio bandwidth requirements because the router
can determine the destination based on IP address, whereas the bridge must go through a learning phase where all
broadcast traffic must be retransmitted on each interface. Routed networks may also be used in some cases to avoid the
overhead introduced by the bridge Spanning Tree Protocol when network loops exist.
Each WDS interface may also be configured with a different encryption algorithm; however each side of a single WDS
link must specify the same encryption algorithm and keys.
Specify SSID for AP/STA modes or MAC Address for Point to point mode.
Router IP and Subnet should be left blank unless that WDS interface is to be on a different subnet. Leaving these fields
blank will mean that the WDS interface will be bridged with the default wireless interface.
When adding WDS router interfaces, you may also need to add a
Routing Rule on the Routing configuration page.
Spanning Tree Protocol (STP) column only applies when two or more interfaces are bridged.
A maximum of 10 WDS Connections can be configured. (A combined maximum of 5 AP and STA virtual modules
applies.)
