Provision of IoT Services for CO-Located 4G/5G Networks Utilisation with Dynamic Frequency Sharing

The Internet of Things (IoT) is an emerging field that has evolved in recent past years and tends to have a major effect on our lives in the coming future. The development of communication techniques is very rapid and tends to achieve many innovative results. With the invention of 5th Generation mobile networks, i.e., 5G, it is becoming an exciting and challenging topic of interest in the field of wireless communication. 5G networks have the ability to connect millions or billions of nodes without affecting the quality of throughput and latency. The 5G technology can develop a truly digital society in which every device may be connected through the Internet. IoT is an emerging technology in which everything can be connected and communicated via the Internet, the term everything may include computing devices, humans, software, platforms, and solutions. The development of this technology leads to the advent of a number of solutions that are helpful for humankind, for example, smart retailing creation of smart cities, smart farming, intelligent transport systems, smart eco-systems, etc. While IoT is a revolutionary technology in the progression of the Internet, it still has some significant challenges for implementation like ensuring security, performance issues, quality of support and saving of energy, etc. Furthermore, the paper elaborates on the motivation of combining two technology together named IoT and 5G for better communication. Additionally, the paper illustrates the basic architecture of IoT enabling 5G and discussed various solutions to provide communication. Moreover, the paper also discussed the various challenges and research gaps of 5G-IoT technology.

5G is the next mobile generation, already being deployed in some countries. It is expected to revolutionize our society, having extremely high target requirements. The use of spectrum is, therefore, tremendously important, as it is a limited and expensive resource. A solution for the spectrum efficiency consists of the use of dynamic spectrum sharing, where an operator can share the spectrum between two different technologies. In this paper, we studied the concept of dynamic spectrum sharing between LTE and 5G New Radio. We presented a solution that allows operators to offer both LTE and New Radio services using the same frequency bands, although in an interleaved mode. We evaluated the performance, in terms of throughput, of a communication system using the dynamic spectrum sharing feature. The results obtained led to the conclusion that using the dynamic spectrum sharing comes with a compromise of a maximum 25% loss on throughput. Nevertheless, the decrease is not that substantial, as the mobile network operator does not need to buy an additional 15 MHz of bandwidth, using the already existing bandwidth of LTE to offer 5G services, leading to cost reduction and an increase in spectrum efficiency.
