Bridge Link Topologies

The IEEE 802.11 standard defines a WIreless Distribution System (WDS) for bridge connections between BSS areas (access points). The outdoor wireless bridge uses WDS to forward traffic on links between units. Up to 16 WDS links can be specified for a SMC2888W-M unit, which acts as the “Master” in the wireless bridge network. SMC2888W-S Slave units support only one WDS link, which must be to the network’s master unit.

The SMC2888W-M and SMC2888W-S support WDS bridge links on either the 5 GHz (802.11a) or 2.4 GHz (802.11b/g) bands and can be used with various external antennas to offer flexible deployment options.
