Wireless Metropolitan Area Networks (WMAN)
A Wireless Metropolitan Area Network (WMAN) is also known as a Wireless Local Loop (WLL). WMANs are based on the IEEE 802.16 standard. Wireless local loop can reach effective transfer speeds of 1 to 10 Mbps within a range of 4 to 10 kilometres, which makes it useful mainly for telecommunications companies.
The best-known wireless metropolitan area network is WiMAX, which can reach speeds on the order of 70 Mbps over a radius of several kilometres.
