The MBS project addresses the system concepts, techniques, and technology required for the transition to the Mobile Broadband System. It will also identify the future communication needs for mobile users, their market characterisation and the impact of the expected evolution of technology on the economic feasibility of widespread introduction of the those services.
The project aims to demonstrate industrial capability to produce the subsystems (RF, IF, and baseband) required by future high data rate communications systems in the cost-effective manner necessary for widespread market introduction.
The research addresses the system concepts, techniques, and technology required for the transition to the mobile broadband system, and the market and economic issues relating to the widespread introduction of the corresponding systems and services. The aim of this research was to identify the future communication needs for mobile users and their market characterization and the impact of the expected evolution of technology on the economic feasibility of those services. The research aims at demonstrating the industrial production capability for the subsystems (radio frequency (RF), intermediate frequency (IF), and baseband) required by future high data rate communications systems in a cost effective manner, compatible with widespread market introduction.
The project studies and defines procedures (routing, handover, channel management, interworking) for the support of mobility under the much stricter requirements imposed by smaller cell sizes. It also develops techniques for micro-cell planning. Studies towards definition of a universal air interface will be undertaken (antennas, modulation, equalisation, coding, multiple access) taking into account the specific characteristics of the 60GHz radio channel. These are placed in the context of evolving architectures for other networks, evolving user needs, and availability of technology. A common performance evaluation methodology and tools are being developed to support this..
Using recent advances in MMIC technology, in particular the pHEMT processes, MBS is designing, implementing and testing moderate-cost systems performing the main millimetre-wave functions required for 60GHz operation. Feasibility of the main concepts (architectural, operational, technological, application) is being demonstrated by transmitting digitised video over a duplex mobile connection using a high data rate (34Mbit/s) mm wave radio link.
- Matching offered services to user needs (applications)
- Cost-effective provision of services.
- Technical issues resulting from operation at much higher radio frequencies (60GHz).
The project will lay the groundwork for the introduction of the Mobile Broadband System from the points of view of the development of system concepts and millimetre-wave components. Through the development and operation of a mobile demonstrator, the project expects to give visibility to the MBS concept thereby stimulating user acceptance of the corresponding services.
