WLL stands for Wireless Local Loop.

• Microwave wireless links can be used to create a wireless local loop such as shown in figure below.

• Local Loop is a network that resides between the central office (CO) and the individual homes and business in close proximity to the central office (CO) as shown in figure above. In most developed countries, copper or optical fiber cable already has been installed to residence and business.

• One more advantage of WLL is that we have to pay only once for that wireless equipment, after there is no additional costs involved. System WLL is based on Cellular, satellite, microcellular. The WLL can greatly improve the telecommunication facilities and services in an inexpensive way.
