Point-to-MultiPoint WDS Network


Point-to-MultiPoint WDS Links (WDS PTMP) 



In a Point-to-MultiPoint Wireless Distribution System (PTMP WDS) the radio on each outlying building (on the circumference of the network) is configured to communicate to the access point on the central building. The links between the central radio hub unit and the "spoke" radios are static and manually configured. There is no "mesh" between the "spoke" radios on the circumference of the network. All outlying radios talk back to the central radio, and never to each other. This type of WDS PTMP network is much more simplistic than mesh routing, where intelligent edge devices auto-discover each other and set up forwarding paths via the shortest route. This type of WDS PTMP network has a single point of complete failure; the central radio. This type of WDS PTMP is, however, significantly less expensive than mesh routing!
