Abstract

There has been a rapid growth in several segments of wireless personal communications in recent years. One of the potential applications of wireless communications is to support multimedia applications on a broadband ATM platform. In such a system, remote terminals may be capable of producing broadband real-time traffic such as variable bit-rate video or bursty instantaneous file transfers.  In this thesis, we will describe a broadband indoor wireless system, where the base stations are connected through the ATM network. The ATM switch provides backbone connectivity among microcells as well as with the outside world. We investigate a broadband indoor wireless network (BIWN) employing Time Division Multiple Access (TDMA), based on polling, for dynamic bandwidth allocation. This thesis work aims at evaluating the performance of an indoor wireless network supporting high speed bursty traffic using a developed, simplified simulation approach. The results have been obtained through simulations which involve modeling the indoor radio channel behavior, traffic heterogeneity and implementing an efficient bandwidth management procedure. The performance of the BIWN as seen by a given user terminal has been simulated.
