Abstract: The ever increasing number of smart network devices may reach up to 24 billion in year 2020 as stated in the recent survey conducted by Forbes magazine. This may obsolete the current 4G technology for handling smart bandwidth allocation to such a large number of devices. In order to cope the challenging need for fast and efficient data transfer over these devices, demands next generation mobile network technology. In literature 5G technology has been suggested that offers appropriate solution to the above issues. 5G is a futuristic technology that would solve many problem of day to day life. By using 5G high data rates can be achieved in the range of Gbps with minimal latency. But the question is how to make such futuristic technology realistic. This can be done by efficiently utilizing the bandwidth in the allotted spectrum. Despite numerous benefits, 5G may critically suffer from tedious implementation problems that have been discussed in this paper. Cognitive radio (CR) is an intelligent radio that works on the principle of dynamic spectrum allocation. Cognitive Radio is capable of learning and adapting to external environment and reuses the frequency when primary user is absent. This paper combine the advantage of two technology 5G terminal and Cognitive radio terminal where 5G provide quality of service and high data rate whereas Cognitive radio give flexibility and adaptability to 5G.
