The ability to provide such services with high flexibility requires the use of new technologies and the extensive changes to existing mobile networks. This paper examines the most important challenges in the implementation of 5G from the technology aspects including mmWave communications, backhaul technology, Technology maturity, energy consumption, EMF and business aspects including business models, ecosystem maturity, Coordination of industry verticals and regulation aspects including spectrum management and fragmentation. Moreover, for some of them solutions suggested by vendor reports and academic works are discussed and analyzed in this article.
