An Investigation into Worldwide Interoperability for Microwave Access (WIMAX) Across the Local Loop

Abstract: The term "wireless" is used to describe communication in which electromagnetic waves or Radio Frequency carries a signal over a communication path. It allows the transfer of information without the use of wires. An access network in the local loop or the last mile is based on the principle of having continuous connectivity between the telephone exchange and the end customer. Over the local loop different technologies can be used to provide a telecommunications based service such as, microwave, radio, fibre or even electricity power cables. In this report, we will concentrate on the new and developing technology called WiMAX - Worldwide Interoperability for microwave access.
