Various complementary radio access networks (RANs) will be used in combination with next generation cellular radio technologies to provide full coverage and advanced services. In particular, the IEEE 802.11 and 802.16 wireless technologies are expected to be the key RANs that can be used to achieve broadband wireless services with varying degrees of mobility. The objectives of this project are to enhance these technologies with participation in IEEE802.11/16 standards activities and to achieve higher spectrum utilization efficiency for the mobile operator use. Currently we work on a variety of challenges, such as seamless mobility support and handoff mechanisms, seamless AAA during handoff, low power consumption for adhoc networks and QoS assurance including support for real-time applications.

UWB (ultra wide band) technology in WPAN (Wireless Personal Area Network) has not only been supporting high speed data transmission, but also designed to be suitable for "Ranging" and "Localization“ use. High accuracy ranging and localization technologies have been studied in this research project. In parallel, we envision the potential of localization in creating new applications and usage models.
