Cognitive Radio (CR) has advanced like a brilliant innovation for crossing over the divergence between the accessibility and assignment of the radio recurrence range among various clients. It can change its transmission parameters dependent on the apparent accessibility of the range groups in its working condition. Cognitive radio (CR) innovation vows to be one potential answer for take care of the issue of absence of recurrence range, by permitting access of unlicensed clients in authorized groups, in view of a shrewd methodology and without meddling with the authorized user(PU). Subjective Radio has developed as a savvy innovation in crossing over the divergence between the accessibility and distribution of the radio recurrence range among numerous clients. This paper shows an outline of the spectrum holes in the licensed bands, the concepts of CR, types, spectrum holes, its features and sensing methods the transceiver details and it compares with conventional radio in terms of performance parameters such as interference, operating frequency, security, spectrum utilization, reliability, efficiency and power consumption
