How Wireless Narrowband Local-Loop Systems in Wimax ?

Naturally, the first application for which a wireless alternative was developed and deployed was voice telephony. These systems, called wireless local-loop (WLL), were quite successful in developing countries such as

How MAC Layer work’s in Wimax?

The MAC layer is oriented to the connections. Each connection corresponds to a service flow. The service flow defines the QoS parameters of PDU transmitted over the connection. The design
