UMTS performance in vicinity of UWB BAN healthcare system

In this paper, we evaluate the performance of UMTS (Universal Mobile Telecommunication System) downlink system in vicinity of a healthcare system. We assume that the healthcare system is a body area network (BAN) system which is based on UWB (Ultra Wide Band) technology. So, the effect of UWB BAN system on UMTS system is investigated by simulation. From the simulation results, we found that the UMTS system is considerably affected by the UWB BAN interference. However, in order to battle this interference and achieve good performance for UMTS system, we found that it is very necessary to carefully raise the UMTS base station transmitted power against that of UWB BAN system. So, the minimum requirements for UMTS system to overcome this interference are stated in this work.
