The wireless local loop (WLL) provides reliable, flexible, and economical access to the local telephone service using radio technology in the place of traditional copper wireline. A variety of wireless technologies are available for the local loop. Digital enhanced cordless telecommunications (DECT) is one of these. Several DECT based WLL products from different vendors have been commercially deployed, or are under trial worldwide. Many of these systems have been installed in rural areas in a single cell-configuration, but many also in built-up areas in multi-cell configurations. The capacity of these multi-cell systems is not well known, due to the variable number of channels available at a given instant in time. In this paper we present the results of thorough simulation of a DECT based WLL system in a multi-cell environment.
