Standards groups and regulatory bodies around the world are increasingly seeking new ways of using and allowing access to allocating spectrum. In most parts of the world, cellular network bands are overloaded, but amateur radio and paging frequencies are not. Independent studies performed in some countries confirmed that observation, and concluded that spectrum utilization depends strongly on time and place. Moreover, fixed spectrum allocation prevents rarely used frequencies (those assigned to specific services) from being used by unlicensed users, even when their transmissions would not interfere at all with the assigned service. In this research we studied the frequency usage pattern of a large telecom company to identify the possibility of establishing a cognitive radio network using their licensed band. Experimental simulation results shows that a carefully designed network will boost the throughput significantly.
