5G Mobile Communication Applications: A Survey and Comparison of Use Cases

Abstract

The mobile demands and future business context are anticipated to be resolved by the fifthgeneration (5G) of mobile communication systems. It is expected to provide an utterly mobile device, connected society, and support the demanding services of various use cases (UCs). This is intended to meet the demand requirement by providing services at tens of Gbps in terms of data rates, higher mobility range, lower latencies, and massive connectivity density devices per square kilometer. A comprehensive and up-todate survey of the different developed and proposed use cases is presented in this paper. The first part of the paper presents the overview of the new 5G Architecture by introducing new features such as the new radio interface (New Radio), an overview of the 5G Core Network, minimum requirements, and the Radio Access Network, 5G spectrum requirements and other fundamentals of the network. Secondly, a detailed review of the developed and proposed use cases for 5G communications by the standards development organizations (SDO) and other key players in mobile communication is provided. Thirdly, we went ahead to propose spectrum bands for the deployment of the various use cases based on the low-, mid-, and high-band spectrum and further classified the use cases with respect to their relevance and family, identifying the IMT-2020 test environments and the usage scenarios derived by the 3GPP, fourthly, the channel capacity and the bandwidth of the spectrum was studied, simulated and compared to ascertain the spectrum proposed in this paper for each UC family. Hence, this paper serves as a guideline for understanding the usage scenarios for the future 5G deployment in various environments. This would allow system developers to design and implement 5G channel characterization models specific to the usage scenarios to meet the system requirements.

Analysis of Scintillation Effects on Free Space Optical Communication Links in South Africa

“…Tables 2-5 show the RMS and ground wind speeds, 2 n C , and scintillation indices for Gaussian beam waves based on the zero inner scale and infinite outer scale model and finite inner and finite outer scale model for various cities in South Africa while taking into account periods not exceeding 50%, 99%, 99.9%, and 99.99% of the time, respectively. The values in these tables are generated based on RMS wind velocities during clear weather periods for each city and their corresponding 2 n C calculated using the HAP model in Equations ( 1) and (2). It is important to reiterate that data spanning many years are necessary in order to accurately estimate the atmospheric turbulence losses that may be encountered by FSOC systems before their deployment to the desired locations.…”

“…The International Mobile Telecommunications 2020 (IMT-2020) specifications, developed by the third generation partnership project (3GPP) for new radio (NR) operations in the fifth generation (5G) spectrum, is expected to accomplish the following performance requirements: ultra-reliable and low latency communications (URLLC) in the user plane as low as 1 ms; massive machine type communications (mMTC) that support up to 1 million devices per square km; and enhanced mobile broadband (eMBB) with uplink and downlink speeds of up to 10 and 20 Gbits/s [1,2]. These technical requirements are needed for the high bandwidth demands of augmented reality (AR), virtual reality (VR), and mixed reality (MR) applications, as well as the seamless and optimal functionality of Massive Internet of Things (MIoT) and Vehicle-to-Everything (V2X) connections for the smooth running of emerging smart cities [3][4][5].…”

“…The mMTC can accommodate a large number of connected devices while maintaining a long battery life. In order to give a nice experience for consumers, routing and switching technologies have also been changed, and 5G technology's coverage area is shorter than 4G [10,12,14,19].…”

“…That resulted in a continuous need for greater traffic volume, device connectivity, speed. This need can only be satisfied by adopting new technologies, that is, the fifth generation (5G) mobile communications [2]. The 5G enhances the network performance with high capacity at a lower cost, which provides the user with very high data rates and a long-awaited end to congestion and latency issues relative to the 4G.…”
