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...
Personal distributed environment securing the dynamic service platforms beyond 3G
Future mobile systems are expected to offer users flexible access to information and services using a combination of different end-user devices in a personal distributed environment (PDE). With PDEs able to operate over multiple air interfa...
Towards a policy based framework for mobile agent authorisation in mobile systems
Mobile agents appear to be a potentially important software paradigm for the mobile domain. If, however, these persistent, autonomous programs are permitted to roam freely in networks, interacting with systems and other agents to fulfil the...
Conformance and security challenges for personal communications in the reconfigurable era
The future generation of mobile communication systems will provide a diversity of services, with the means of secure software download and transparent reconfigurability, providing increased opportunity to all parties in the telecommunicatio...
