Meshing?I.E. hub stacking

There?s a lot of overhead involved in a mesh network and a lot of extra traffic to allow the units to mesh, and WiMAX isn?t exactly high bandwidth. Anybody who?s built a WiFi network with users in excess of 30 per AP will see how quickly the network can become crowded. Even if WiMAX makes great strides past WiFi you can?t get around the fact that the air acts as a single shared bus for everybody within the 30 mile range of the transmitter. Any system that uses individual switched wire connections between users will have more bandwidth and more expandability.

Wireless products work like hubs, and you network a bunch of hubs together with hundreds of users you?ll use up that 50Mbps bus real fast. WiMAX will be a great alternative to broadband but it won?t takeover the established infrastructure.

Even if each WiMAX AP is hardwired into a switch you?ll still have to deal with interference from overlapping APs and the fact that each non-overlapping channel will max out when the number of users inside the 30 miles radius reaches a certain point. For a 802.11g APs you?re lucky to get 25 clients sharing the 54Mbps throughput, any more and the connection speeds drop below dial up rates.
