Although the technology holds much promise, it is a radical departure from the existing methods of spectrum regulation. Complications exist from both a technical and a regulatory standpoint with the introduction of this new technology.
On the regulatory side consideration must be given as to the most appropriate mechanisms to allow CR. Over the coming year we are undertaking a study to investigate the issues surrounding introduction of CR technology and to develop a simple software demonstrator system to investigate issues. Quantifying the gains in spectrum efficiency and utilisation that would result from the CR approach, and estimating the increased level of activity possible and the consequential economic benefit.
Considering the regulatory impact of CR and what actions could be taken to facilitate deployment and maximise the benefits of the technology. Spectrum Utilisation There is potential to make considerably better usage of the radio-spectrum. Studies undertaken by Ofcom have investigated the usage of the radio spectrum.
These measurements appear to indicate that there are many areas of the radio spectrum which are not fully utilised in different geographical areas of the country. Figure 2 Spectrum occupancy measurements in a rural area top , near Heathrow airport middle and in central London bottom There are some caveats which must accompany the figures, for example some low level signals may not have been picked up and thus activity levels will be indicated as lower than is truly the case.
Nevertheless, such measurements indicate the potential gains that might be accrued from a system which was able to sense its radio environment and utilise it effectively. Our research in this area will establish the likely timescales for deployment of practical applications employing CR technology, bringing together the existing work in the different underpinning technology areas such as wideband antenna development and SDR.

Some "smart radio" proposals combine wireless mesh network —dynamically changing the path messages take between two given nodes using cooperative diversity ; cognitive radio—dynamically changing the frequency band used by messages between two consecutive nodes on the path; and software-defined radio —dynamically changing the protocol used by message between two consecutive nodes.
