Abstract
Personal communications is a rapidly expanding field with many potential applications. The 20 GHz to 60 GHz (mm-wave) band appears to be a suitable choice for providing wireless indoor access to voice, data, video and other services, since it offers large bandwidth, current sparse usage, small RF device dimensions, and short range propagation suitable for microcellular system architectures. Reception of mm-wave signals in buildings is governed by attenuation by walls, doors, etc., by multipath effects due to scattering from the same, and by interference from other users. Time Division Multiple Access (TDMA) system operating with Time Division Duplex (TDD) is considered as a representative multiple-access algorithm.
This thesis discusses the results on the performance characteristics viz, blocking, co-channel interference, and transmission quality of indoor wireless communications in the (20-60) GHz band. Among the factors and parameters considered are traffic demand, density and types of users and their required bandwidths, numbers of frequencies assigned and various channel assignment algorithms. The results have been obtained through simulations of a typical indoor environment, with propagation parameters typical of the mm-wave propagation.
