A Hybrid Architecture of Umts and Bluetooth for Indoor Wireless/mobile Communications

Over the past several years, mobile/wireless communications have evolved and proliferated a variety of technologies. Among those technologies, we focus on UMTS and Bluetooth because of their prominent and complementary features. While UMTS provides “universal connectivity,” Bluetooth will be the most promising candidate technology to provide “ubiquitous connectivity.” In this paper, we advocate that a hybrid architecture of UMTS and Bluetooth provides a “one-architecture-fits-all” paradigm for any wireless communications. We detail the proposed architecture in indoor environments, where UMTS-TDD is chosen for connecting Bluetooth piconets and scatternets. The key node in this architecture is a “hybrid device” equipped with both UMTS and Bluetooth interfaces. The performance of the architecture is evaluated by simulation experiments under different configurations.
