Spectrum Sharing for Unlicensed 5G Networks

5th generation wireless ICT eco-system promises three important pillars of network innovation: (a) Ultra Reliable Low Latency Communication, (b) Enhanced gigabits wireless broadband and (c) massive machine type communication. 5G is expected to transform the way humans and devices communicate and exchange services and improved automation of industry. The aim of this paper is to discuss recent research in spectrum sharing and unlicensed wireless networks, including its extension to 5G research based on use cases and associated technologies to address the requirements of affordable wireless broadband. The paper presents research contributions on spectrum toolboxes, including smart spectrum sharing for 5G and affordable networks. The research outcome will be presented with a proof of concept network test-bed developed in South Africa. Finally the paper will conclude with a challenge to existing and future research in technology standards for 5G to contribute towards the achievement of universal affordable broadband for the next billion customers.
