Potential Technologies to 5G Network: Challenges and Opportunities

Recently, there has been a substantial growth in mobile data traffic due to the widespread of data hungry devices such as smart handsets and laptops. This has encouraged researchers and system designers to develop a further efficient network design. The objective of this paper is to overview the technologies that can support multi Gbps for future Fifth Generation (5G) network. This paper presents many challenges, problems and questions that arise in research and design stage. It concluded that the anticipated high traffic demands and low latency requirements stemmed from the Internet of Things (IoT) and Machine to Machine Communications (M2M) can only be met with radical changes to the network paradigm such as harnessing millimetre-wave band in dense deployment of smallcells. Future wireless system will include all types of smart features and applications that make 5G the most intelligent and dominant wireless technology.
