One hundred years of spectrum sharing based on reuse the frequency bands that the primary users are not fixed frequency allocations have led to fracturing and poor using at a particular time and a particular location. The utilization. Present methods of frequency allocation combined terminal will be able to migrate from infrastructurewith a reliance on fixed infrastructure threaten to halt this growth. An additional consequence is the deployment of supported eionet comuncai on within n ms

This paper outlines a vision of a intelligent and cooperative sensing of unutilized bands. The system that, by enabling the secondary use of spectrum on an concept of secondary use of the spectrum, known as opportunistic basis and by establishing collaboration between cognitive radio [1][2], in combination with advanced the users, would enable a realization of ubiquitous, robust and cooperation between system components is enabled by agile wireless systems that are able to support further traffic advances in fundamental communications and networking growth and changing demands in traffic. theory and continued improvements in integrated circuit technology. Because of its universal functionality, the same CMOs. t device can be used for many applications that otherwise require dedicated and expensive low-volume solutions. It is envisioned that a system like this would be able to support
