Understanding the challenges towards implementation of the 5G wireless networks

The cellular communications have grown rapidly in past few decades and it is inevitable that the cell communications is moving toward paradigm shift where the users will be provided connectivity through heterogeneous networks. The new generation of mobile networks is expected to evolve around 2020, which is now commonly known as 5G. Currently, the researchers are struggling to explore about how the users will be served with an increase of tens and hundreds of user devices. However, there are various challenges that need to be addressed before the wireless infrastructure will be capable to furnish the requirements of 5G. This paper insights about the requirements and challenges that are necessary for the realization of the 5G networks.
