Technologies Trend in the Integration of 5G Networks and IoT in Smart Cities: A Survey
Abstract---This paper presents a survey of 5G and suitable concerns in the planning and development of communication model infrastructure for the deployment of Smart Cities, also called Intelligent Cities or Digital Cities. The paper first provides an overview of 5G technology, its evolution, and how it revolutionised worldwide communication. The drivers of 5G, such as enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), and massive machine-type communication (mMTC), will enable 5G to deliver higher speeds compared to the previous 4G and 3G generations and enable service providers to provide massive bandwidth catering to data-intensive applications such as Smart Cities. Besides human-computer interaction (HCI), smart cities include machinetype communication (MTC), in which massive communication takes place between devices and the information infrastructure through gateways. A 5G network can successfully integrate the diversified service requirements and demands of smart city applications. Smart cities require massive IoT communication built into 5G. Multiple technologies are deployed in smart cities to enhance the standard of living for people. Citizens are provided with better health services, improved transportation, efficient energy, quality education, and safety and security to public. In this survey paper we present the contribution of 5G in the deployment of smart city applications and its pillars that play a very important role in the construction of smart cities. Better healthcare systems have been developed that integrate new communication technologies and conventional health care procedures. One of the vital segments of a smart city is its transportation system, which affects the environs and health of people. The energy efficiency of smart cities can be greatly improved by 5G by using smart appliances. Smart metres deliver real-time data about the energy consumed. Users can save energy and money. Similarly, it can assist the water board team by giving real-time statistics regarding water consumption to the consumers. Almost all the smart city infrastructure mentioned above has different requirements for delay, movement, dependability, and resilience of the network. Incorporating diverse applications into a communication network is a difficult chore. 5G has been designed for forward compatibility to support future amenities not known today. The paper outlines diverse requirements for smart cities based on application and technology requirements. Lastly, the supporting technologies are highlighted for the forthcoming integration of smart cities and communication infrastructure.
