چکیده
Sometimes called radio in the loop (RITL) or fixed-radio access (FRA), wireless local loop (WLL) is a system that connects subscribers to the public switched telephone network (PSTN) using radio signals as a substitute for copper for all or part of the connection between the subscriber and the switch. This includes cordless access systems, proprietary fixed radio access, and fixed cellular systems.

Performance Analysis of a Cdma Wireless Local Loop Systems
In this paper, the capacity of the Code Division Multiple Access Wireless Local Loop (CDMA WLL) system is analytically derived, and the capacity gain achieved in a CDMA WLL over a cellular mobile environment is calculated. The results show that the CDMA WLL system can support up to 36 % more users than CDMA cellular mobile system. The paper also propose a new approach to increase the reverse li...

متن کاملCapacity of broadband CDMA wireless local loop systems
Wireless Local Loop (WLL) is an emerging technology that allows rapid connection to the wired network from remote locations. A crucial issue for WLL is the system design so that the number of subscribers can be maximized while providing the required quality of service. In this paper, we consider a broadband wireless local loop with fixed point users and we evaluate the subscriber capacity for a...
متن کاملHow to Measure Spectrum Efficiency
n the ’70s fixed-to-fixed microwave links were developed and deployed. Wireless local loop (WLL) systems could also have been implemented in the ’70s in U.S. rural areas, but were not. The cost justifications at that time for WLL were: For the Near Term — Using the radio link for WLL was the solution because the cost of laying a long wire cable to connect to a remote point was very high. For th...
