Dynamic Spectrum Access
The currently used mechanisms for spectrum management are a contributing factor to the long lead times from innovation to market in wireless technologies and systems. This has in turn been a major contributing factor to the dominance of the large telecom companies in the European and World markets, whereas very few innovative enterprises have exhibited consistant growth, although the technical competence in Sweden is very high in this area. Alternative spectrum management regimes, such as. the introduction of "unlicensed bands" have proven very effective in lowering entry thresholds for smaller companies (e.g the WLAN business). In addition, experts claim that the spectrum requirements for communication purposes will increase by as much as 200-300 % up to 2010. At the same time the actual usage of the electromagnetic spectrum is very inefficient.
Project objectives:
The project aims at studying new spectrum allocation regimes which, i combination with new technologies, such as multi-radio access, novel broadband access techniques, software defined radio and spatial techniques (e.g. smart antennas, multi-hop schemes) have the potential of lowering the entry thresholds for new actors and provide radical improvement to the effenciency of spectrum usage. Further the aim is to investigate the economic and regulatory consequences of such technologies and management regimes. The results will provide input to future policies in spectrum management.
The project is organized in two phases
