The 5G wireless mobile network addresses the evolution beyond mobile internet to massive IoT (Internet of Things) from 2019/2020 onwards. The most evolution compared with today’s 4G and 4.5G (LTE advanced) is that data speed enhancements. Past simply speed enhancements, 5G is relied upon to release a tremendous IoT ecosystem any place systems will serve communication for billions of associated gadgets, with the best possible trade-offs between speed, latency and cost. Like all wireless transmission system, 5G network also require to use frequency spectrum to transmit data. So as to support higher bandwidth, 5G require high frequency range, presently upto a couple of tens of GHz and millimetre waves, however that the new network generates radio frequency radiation will injury deoxyribonucleic acid and result in cancer and it will increase the path loss. So, one various to attain these objectives with reducing impact of radiation on health risks is to use different accessing techniques in outdoor and indoor environments. The light fidelity (Li-Fi) with the cognitive radio (CR) technology is one of the promising solutions to extend the transmission capacity in the indoor scenario. It is based on light emitting diodes (LEDs) to enable high speed communication and secure data transmission in communications with fully networking capabilities. This paper administers recent advances in analysis associated with Li-Fi technology with cognitive radio technology in 5G technology, diversifying the wireless communication with hiking spectrum utilization and immense capacity.
