Broadcast in 5G Wireless Communication Networks and Beyond: An Overview of Public Safety Communications

Abstract

The objective of this paper is to cover the present and future scope of the public safety communication, which targets timely and accurate delivery of critical information. The evolution of these services over the generations of wireless communication networks (WCNs) has been discussed in this paper. The basic broadcasting mechanism, for the dissemination of essential information during emergency and lockdown has been described, followed by the supporting architectures for information broadcasting. The role of various technologies of the 5G WCNs, and beyond, in improving the efficiency of the functioning of these networks has been stated. The technologies include spectrum sharing, network slicing, software defined networking (SDN), augmented reality (AR) and virtual reality (VR). A seamless integration of these technologies can help in achieving high efficiency, optimal resource and power availability. Challenges in executing these are also discussed.
