As demand for multimedia wireless services increase, spectrum congestion forces system planncr to consider the use of radio links operating at millimetre wave band. However, the high signal propagation impairment such as rain attenuation, shadowing and multi-path fading effects are the dominant causes of signal degradation at those frequencies. In this paper, performances of local multipoint distribution service (LMDS) system is analysed by considering these channel characteristics based on proposed cellular pattern. Results show the proposed cellular improve system performance by reducing the number of near interfering sources.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
