Question 1

What are the two primary goals of WMANs?

Accepted Answer

To extend the reach of existing wired networks beyond a single location without the expense of deploying and maintaining high-speed wire or optical-cable-based connections.
To extend user mobility throughout a metropolitan area. An important additional benefit of a WMAN is that it can provide high-speed connections, including Internet, to areas not serviced by any other method of connectivity. Such connectivity can encompass metropolitan areas, expanding to small towns nearby, as well as to remote locations not usually serviced by high-speed communications lines.
