Realization of Smart City Using 5G Cognitive Radio

The aim of this paper is to advance certain understandings and concepts for adoption in wireless systems to be deployed beyond the year 2020, providing the data rate up to 1GBPS, referred to here as 5G. and same can be used for realization of smart cities. Next generation communication systems are expected to be intelligent in nature, as well as providing a platform for operators to effectively exploit their network resources in an era where spectral resources are at a premium. The smart cities can be designed based on cognitive radio which is meant for spectrum sensing and spatial sensing. It also uses the massive MIMO and the heterogeneous network which uses small cells called Femto/Pigo cell. This paper describes how the 5G wireless communication system can be modeled with the cognitive radio and the MIMO based smart antenna and further it can be used for realizing smart cities. The 5G uses the millimeter wave access technology where the spectrum above 6GHz can be exploited. The cellular architecture is modeled and explained for smart cities, which enables the low power consumption.
