Messaging in a 3G world
Messaging is now used billions of times a day to communicate person to person and person to application. Yet despite the success, the number of messaging technologies presents problems for users and potentially inhibits even larger take-up....
Comparison of space-time architecture performance for UMTS under time-varying Rayleigh fading channel
Recent advances in space-time signal processing have enabled the realization of multiple-input multiple-output (MIMO) communication systems. It is highly probable that MIMO architectures will be important contenders for the next generation ...
Utility-based distributed geographic load balancing in mobile cellular networks
The paper describes a new approach to geographic load balancing in mobile cellular networks with fully adaptive antennas. Our previous work using cooperative negotiation and semi-smart antennas has been shown to be very effective, however, ...
Smart antennas in handsets for improving 3G performance
The improvement in network performance due to the use of smart antennas in UTRA FDD handsets is investigated. A statistical model was derived, from published results, for the performance of a handset having a smart antenna. This model was u...
Two-dwell code acquisition techniques by advanced spatio-temporal antennas for the radio access of 3G mobile communications
Serial multi-dwell probability tests are usually adopted for initial code acquisition in the radio access of 3G mobile communications. This contribution extends the analysis to the case of smart antennas and MIMO systems, involving 2D spati...
Automatic optimisation for UMTS indoor coverage using distributed antenna systems
With the shift of focus from 2G to 3G systems, there is a tendency to evolve towards picocellular environments, which can provide coverage to hotspots inside buildings. At the same time, interference management has become a key issue, since...
Indoor FDD multi-operator deployment
The performance of UTRA-FDD was assessed under multi-operator deployments in an indoor office environment. A modified version of the proposed 3GPP picocell scenario was used, with two deployed operators, each having 5 base stations (BS). Tw...
A novel code planning approach for a WCDMA network
This paper explains the background to WCDMA code planning and the theory behind the Orange code planning technique. It then goes on to describe the tests performed on the Orange WCDMA test platform and network and the results achieved. Fina...
Radio planning and optimisation - the challenge ahead
The paper tries to identify some significant areas where challenges remain in the planning and optimisation of radio networks. There is no attempt to create an exhaustive list of challenges, nor is it suggested that the challenges all remai...
Novel m-commerce security protocol for third generation mobile networks
A new protocol for electronic commerce is proposed; it is fully applicable to 3rd generation mobile networks. The protocol is characterised by three novel properties as opposed to existing methods of exchanging goods. It provides a simplifi...
