Abstract—The telecommunication industry has been
through disruptive times, but data networking service
revenue has continued to rise. The telecom industry is
expected to continue to grow as demand increases for cable
and high-speed Internet in previously unserviced locations
and as local telephone companies upgrade their lines in
response to increasing competition. This paper presents an
extended overview of the Worldwide Interoperability for
Microwave Access (WiMAX) and its applications in higher
generation wireless networks as a cost effective solution to
answering the challenges posed by the digital divide. It
looks at the technology behind WiMAX and networks
design and deployment factors that impact WiMAX
coverage. A cell site coverage simulation at different
frequency bands using Wireless simulation tool is presented.
Also the paper makes a comparison of WiMAX with two
enhanced third generation (3G) technologies that are
potential competitors to WiMAX. It then goes on describe
the business models in WiMAX and states some of the
benefits and drawbacks of a mobile WiMAX network.
