WLL stands for "Wireless Local Loop," and it refers to a telecommunications system that enables wireless connectivity between local telephone customers and the telephone exchange.
In traditional telephone systems, copper cables are used to establish a physical connection between telephone users and the exchange. However, WLL systems replace the physical link with wireless technology, eliminating the need for extensive cable infrastructure.
The WLL system uses base stations, antennas, and microwave links to provide connectivity. Base stations are strategically placed throughout a coverage area and wirelessly communicate with handheld or desktop telephones used by local customers. The signals are transmitted using microwave links, which can transmit data over long distances without significant losses.
WLL systems offer several benefits. Firstly, they reduce infrastructure costs, as there is no need to lay down extensive copper cables. This makes them particularly useful in remote or rural areas with limited telecommunications infrastructure. Secondly, WLL systems provide quick deployment, as setting up base stations and antennas is relatively easier compared to laying physical cables.
Furthermore, WLL systems can offer additional features such as call waiting, caller ID, and voice encryption, enhancing the overall telephone experience. They also support data transmission and internet connectivity, allowing users to access the internet wirelessly.
Overall, WLL systems have revolutionized telecommunications by providing wireless connectivity to local telephone customers, contributing to the expansion of telecommunications services in both urban and rural areas.
