Wireless local loop is used for wireless communication links which deliver plain old telephone services or broadband services to customers. This is an ideal application which provides telephone services remotely and is mostly used in developing countries where cable infrastructure is either expensive or speed is not fast.
Loop:. In telephone, loop is a circuit line from a subscriber’s phone to a line terminating equipment at a central office. Wireless Local Loop (WLL): • Implementation of a local loop especially in rural areas used to remain a risk for many operators due to less users and increased cost of materials.
Wireless local loop (WLL), is the use of a wireless communications link as the "last mile first mile" connection for delivering plain old telephone service (POTS) or Internet access (marketed under the term "broadband") to telecommunications customers. Various types of WLL systems and technologies exist.
WLL (Wireless Local Loop) basics Tutorial. The need of internet is increasing day by day across the globe. This leads to providing broadband internet to users in the office premises as well as residential places. There are various ways internet can be provided to the users such as fiber optic cable, DSL line and wireless connectivity.
Abstract: Wireless local loop (WLL) provides two way calling services to the stationary or "fixed" users, which is intended to replace its wireline counterpart. Today, there are almost 100 WLL systems (either trials or commercial systems). This article describes the WLL architecture, the WLL technologies, WLL service descriptions, and some examples of WLL products.

Wireless Local Loop Seminar and PPT with pdf report: In the telephone networks, the circuit between the subscribers’ tool i.e. the telephone set and the local exchange is known as the local loop.To furnish the voice and voice band services to the local loop, the copper wire plays the role of a medium.
In this video the architectural model and example of the above theories are explained Wireless Application Protocol Mobile IP Wireless local loop ~ ~~...
The local loop may terminate at a circuit switch owned by a competitive local exchange carrier and housed in a point of presence (POP), which typically is an incumbent local exchange carrier telephone exchange. A local loop supports voice and or data communications applications in the following ways: analog voice and signaling used in ...
Wireless Local Area Network (WLAN) This network enables you to access the Internet in localized hotspots via a wireless local area network (WLAN) access card and a PDA or laptop. It is a type of local area network that uses high frequency radio waves rather than wires to communicate between nodes.
