Towards 6G wireless networks-challenges and potential technologies

Abstract

As 5G technology is advancing towards its final phase of development and the deployment of 5G networks is underway, academic, development and industrial communities are already moving towards the research and development of 6G wireless networks. While 5G technologies had been hauled as an enabler for Internet of Everything, many limitations of such cellular systems are coming to light as they are being deployed. These drawbacks of 5G networks have motivated worldwide interest on developing the next generation wireless system, 6G, with the capability to fully incorporate wide-ranging applications from virtual reality to autonomous systems. In this paper, an overview of the first five generations of wireless systems has been shown, followed by a survey on 6G wireless network along with a discussion on the possible requirements and challenges of 6G.
