Which of the following describes a wireless MAN (WMAN)?

A wireless MAN (WMAN) is characterized as a metro area network that utilizes radio signals to transmit and receive data. This type of network bridges the gap between local area networks (LANs) and wide area networks (WANs).

The defining feature of a WMAN is its capacity to cover a larger geographical area than a LAN, extending to the scope of a city or a metropolitan area, while employing wireless communication methods. By leveraging wireless technologies, WMANs can facilitate connectivity without the need for extensive cabling, allowing for greater flexibility and ease of deployment in urban settings.

This is particularly advantageous for applications like internet service provision in metropolitan areas, public safety communications, and other municipal services that require an efficient and scalable network solution. The use of radio frequencies for data transmission is key, as it allows for mobility and the ability to connect multiple devices over several square miles, without the infrastructure limitations of wired networks.
