The frequency spectrum is a limited resource, so efficient use of frequency is very important. Cognitive Radio Network (CRN) is an intelligent network, which can distribute the unused frequency i.e. white spaces to the Secondary Users (SUs) without interference with Primary Users (PUs). To avoid interference with PUs, the SUs are needed to hop from one white space to another white space within a specific time interval. The paper proposes factors to be taken into account while implementing a Cognitive Radio Network which include allocation of white spaces, channel identification, dynamic spectrum management and transmit-power control, signal propagation effects, active spectrum sensing techniques, interference temperature, spectrum sensing and estimation/prediction of primary user traffic.

Cognitive Radio Network

Cognitive cycle

channel identification

Spectrum management

Transmit power control

The paper gives a brief on factors to be considered for implementing Cognitive Radio Network. Implementing each cognitive task is a challenge in itself. So proper estimation of these values is needed while building Cognitive Radio Network.
