ABSTRACT
5th Generation (5G) wireless systems is referred as beyond 2020 mobile communications which means the 5G standards can be introduced in early 2020s. Today’s current advanced technology is LTE advanced, which provides a peak download speed of 1 Gbps and upload speed of 512 Mbps. By 2020 and beyond the wireless devices would be approximately 7 trillion and therefore the traffic will rise manifold as compared with today. 5G system should be an intelligent technology capable of interconnecting the entire world without limits. Cognitive radio technology will be more efficient radio communications systems to be developed. This new radio technology share the same spectrum efficiently by finding unused spectrum and adapting the transmission scheme to the requirements of the technologies currently sharing the spectrum. Multi homing is a technique used to increase the reliability of the Internet connection for an IP network.
