5G WIRELESS TECHNOLOGY

What the 5G will be? W ill it be an incremental advance on 4G. The previo us four generations of cellular technology have made a major pattern shift that has broken the compatibilit y with respect to its p revious generation. Indeed, 5G will also need to be a paradigm shift that includes high carrier frequencies with massive bandwidths, huge bas e station and device densities, and large number o f antennas. However , it will al so be highly integrative: tying an y new 5G air interface and spectrum together with LTE and WiFi to provide high - ra te coverage and a seamless user experience. But for this, the core network will also have to reach a very high - level of flexibility and intelligence, spectrum regulation impro ved, and energy and cost efficiencies will become eve n more critical considerations. This paper discusses all of these top ics, identifying challenges to occur in future research and preliminary 5G standardization activities
