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.
