In a wireless Wide Area Network, the physics of RF are basically the same as they are in a WLAN. In terms of signal propagation, attenuation, reflection and refraction, atmospheric absorbtion, etc the concepts are the same, but of course on a different scale when talking about longer distances.
In a wireless WAN you typically have your mobile devices (think of a cell phone) that connect to their local base station. The base stations themselves do not generally communicate wirelessly, but have connections to a wired network. In the event it's all wireless (even between base stations) then it's most likely microwave links, either terrestrial microwave (base station to base station, maybe with repeaters in between) or via satellite.

I would think that you meant LAN for a Local Area Network...
but either way I'd think it works pretty much the same as a cordless phone.
Base unit, hand-held unit, transmitter and receivers, "hand-shaking" to negotiate the best signal that can be authenticated. Transferring ones and zeros.

Have a look around the Web for 802.11 (WiFi), 802.16 (WiMax), LMDS... depends whether you are looking for point-to-point small scale, or point-to-multipoint city size.
