Abstract : The underlying theme of this half-day tutorial is twofold: (i) to explore imminent as well as prospective challenges opened up by the evolution and revolution happening in the domain of wireless mobile communication which is poised to enter into its fifth generation (5G), and (ii) to weigh the advancements made till date towards B4G/5G against those challenges, satisfying all the new emerging requirements. The number of wireless devices is increasing every day, and very soon we shall reach a “disruptive” situation, where (a) diverse, bandwidth-hungry services appear and vanish pervasively, (b) augmented reality and real-time interaction will be common as devices are embedded into areas of social life and industry (cyber-physical-social systems), (c) devices, particularly smartphones, become even more powerful to become gateways (for other devices) to access services from the cloud, (d) tiny devices access the Internet (Internet of Things), and M2M communication uses broadband services, and (e) per-user storage and processing requirements will further increase. In order to accommodate these emerging demands, next generation 5G systems and applications need to be further evolved based on fundamental and innovative rethinking of the conventional mobile and wireless communications and technologies. So, in essence, the moot question is how 5G will be able to support the following characteristics: (a) “Amazingly fast”, (b) “Great service in a crowd”, (c) “Best experience follows you”, (d) “Super real-time and reliable connections”, and (e) “Ubiquitous things communicating”.
