The project aims to improve the accuracy of automatic location identification of GPS enabled handsets in third-generation cellular networks via a modified Differential GPS method. The proposed sub-metre location ability will be a value-added service of the network providers and will appeal to a wide sector of users. The challenge is to develop a cost effective solution by utilising existing network infrastructure. We propose to use the GPS timing units in 3G networks for deriving local GPS position corrections; and to transfer these corrections to the users via the 3G data bursts of the beacons or other user data broadcasts.Read moreRead less

Meeting the global demand for mobile and wireless communications depends critically on reliable and high rate data transfer. Unfortunately, communications medium idiosyncrasies pose formidable challenges. Very recently, in combatting this, major breakthroughs have been achieved whereby the use of multiple antennas allows for drastic data-rate increases. These advances use sophisticated Space-Time coding methods, and while they are causing great excitement in terms of their simulation performance, it is not clear how they will perform in practice, or in fact how they are to be realistically implemented. This project will address this issue by building a world-first testbed that implements a high rate wireless communications system using Space-Time and other coding methods.Read moreRead less

Expansion of Wireless LANs as primary access technology for mobile computing devices has resulted in growing expectations of continuous area coverage and controlled Quality of Service. The work published to date defines QoS control mechanisms for a single WLAN cell, but fails to address challenges of multiple-cell networks. We aim at designing network-wide resource management mechanisms to dynamically allocate resources to cells and users, taking into account user mobility and radio interference between multiple cells. Benefits from this research include competitive advantage to operators who will be able to differentiate service offerings and guarantee agreed QoS to their customers.Read moreRead less
