WiMax (MAN) deployments are similar to a WiFi network. First the ISP would have their T3 or higher access. The ISP would then use line of sight antennas (Bridges) to connect to towers that would distribute the non line of sight signal to (MAN) residential/business clients.

WiMax line of sight antennas operate at a higher Frequency up to 66MHz. Distribution antennas do not have to be in the line of sight with their clients. Non - line of sight towers operate on a range similar to WiFi . WiMax can operate right next to cell phone towers with no interference.

WiMax networks are similar to Wifi in deployment. The Wimax Base station/Tower will beam a signal to a WiMax Receiver. Similar to a WiFi access point sending a signal to a laptop. As far as I can tell laptops will be shipping with Wimax receivers in 2006.
