Title

UMTS-TDD: A Solution for Internetworking Bluetooth Piconets in Indoor Environments

Abstract

The last few years have seen the evolution of telecommunications from the classic architectures, mainly based on static and wired structures, to the new mobile solutions based on wireless technologies. This trend has led, on the one side, to the definition of the third–generation mobile telecommunication systems and, on the other, to the development of personal area networks. The standards that are supposed to play a leading role in these two fields in the near future are the Universal Mobile Telecommunication System (UMTS) and the Bluetooth (BT) radio technology, respectively. In this paper, we advocate that a hybrid architecture of UMTS and Bluetooth can take advantage of the complementary characteristics of these two technologies and provide a total solution for an indoor communication environment. We envision a cooperating scenario in which small Bluetooth networks (scatternets) offer basic wireless connectivity to several peripheral units scattered over small areas, while indoor UMTS supports communication among scatternets and provides wireless access to the Internet. We focus our analysis on a centralized topology, in which communication occurs only between the peripheral units and the access point. This topology can be used in many different application scenarios and represents an example of cooperation between 3G and PAN technologies. In addition to describing the architecture, we address the issue of fair capacity allocation in such a centralized topology and provide some analytic and simulation results for the topology considered.
