WiMAX system consists of two parts:
A WiMAX tower, similar in concept to
a cell-phone tower - A single WiMAX
tower can provide coverage to a very
large area -- as big as 3,000 square miles
(~8,000 square km).
A WiMAX receiver - The receiver and
antenna could be a small box or they could be built into a laptop the way Wi-Fi access is today

A WiMAX tower station can connect directly to the Internet using a high-bandwidth, wired connection (for example, a T3 line).
It can also connect to another WiMAX tower using a line-of-sight, microwave link. This connection to a second tower (often referred to as a backhaul)
Along with the ability of a single tower to cover up to 3,000 square miles, is what allows WiMAX to provide coverage to remote rural areas.

The fig. shows the points out is that WiMAX actually can provide two forms of wireless service :

non-line-of-sight:
A small antenna on your computer connects to the tower.
lower frequency range -- 2 GHz to 11 GHz (similar to WiFi).
Lower-wavelength transmissions are not as easily disrupted by physical obstructions

line-of-sight service:
fixed dish antenna .
connection is stronger and more stable, so it's able to send a lot of data with fewer errors.
higher frequencies, with ranges reaching a possible 66 GHz.
Wi-Fi style access will be limited to a 4-to-6 mile radius Through the stronger line-of-sight antennas, the WiMAX transmitting station would send data to WiMAX-enabled computers or routers set up within the transmitter's 30-mile radius (2,800 square miles or 9,300 square km of coverage). This is what allows WiMAX to achieve its maximum range.
