This paper investigates the migration from 4G to 5G mobile communication networks, focusing on three core areas: the enhancements 5G brings to communication, the challenges associated with migration, and strategies to maximize 5G effectiveness. The paper reviews the evolution of mobile networks from 2G through 4G, explains the drivers behind 5G adoption — including the Internet of Things, low-latency demands, and exponential device growth — and analyzes risks such as wireless system selection, jamming, spoofing, and security vulnerabilities. It also outlines deployment architectures and the infrastructural and regulatory requirements necessary for a successful 4G-to-5G transition.
Aim 1: To determine how the migration from 4G to 5G will enhance communication.
The primary aim of this dissertation is to determine how the migration from 4G to 5G will enhance communication. Migration to 5G is expected to bring various enhancements compared to 4G. These enhancements include lower latencies, higher speeds, lower power consumption, enhanced reliability, and greater terminal device densities. Perhaps the most important feature of 5G is the new network capability that could allow several virtual networks with differential performance characteristics to be supported by a single physical network (Alkhazaali 2017). Given these capabilities, this paper aims to determine how communication will be enhanced.
Aim 2: To identify some of the challenges of 5G.
Experience has shown that technology, however advanced, carries peculiar limitations that make it vulnerable. As a result, this dissertation seeks to identify the challenges attached to migration from 4G to 5G. 5G is a term used to refer to communication standards beyond 4G, and the projected timeline for widespread deployment of 5G was set for 2020. Given the disruptions caused by the COVID-19 pandemic, it was expected that this projection would not hold and that an extension would be inevitable. Among the constraints attached to migration from 4G to 5G are multi-mode user terminals, security concerns, the choice among various wireless systems available, jamming and spoofing, and network infrastructure and Quality of Service (QoS) support (Alkhazaali 2017).
Aim 3: To establish strategies to maximize the effectiveness of 5G for those migrating from 4G.
In light of the expected challenges, this dissertation aims to present expert suggestions on the various strategies that can be used to address the difficulties facing migration from 4G to 5G. These strategies will include possible technological adjustments to improve 5G performance, support systems, and potential improvements that can be incorporated into the next generation of network development.
The objectives of the dissertation are:
(i) To determine the specific aspects of 5G over 4G that could contribute to communication enhancement.
(ii) To establish expert opinions on the constraints that face migration from 4G to 5G.
(iii) To determine field experience with the migration to and use of 5G.
(iv) To determine expert opinions on potential solutions to the challenges facing 4G migration and possible improvements to enhance the effectiveness of 5G.
Communication networks have made significant improvements in recent years. Over the last decade, mobile communication networks have developed from Bluetooth, WLAN, 2G, and 3G to 4G. With a specific focus on 4G — the most predominant and widely used network at present — it is a network developed to enhance seamless integration of cellular networks such as 3G and GSM (Alkhazaali 2017; Gandotra and Jha 2016). Currently, a combination of wireless networks, including WLAN and PLMN, is in use.
The development of 4G was driven by unprecedented and ever-increasing growth in users and demand for data traffic, as well as the emergence of new technologies and applications in mobile communication. The development of 3G led to the advanced technological requirements for 4G, which introduced a data rate of 1 Gbps downlink and 500 Mbps uplink (Tehrani et al. 2014). However, the number of networked devices and the need for applications requiring low latency and high data throughput have since increased exponentially. The projection is that current 4G technologies will reach their limits in the near term, necessitating the move to 5G networks.
The Internet of Things (IoT) has further concentrated internet usage, meaning that communication is no longer limited to person-to-person exchanges but also encompasses device-to-device (D2D) communication. The increased demand for very high data rates and low-latency networks is a key driver of the 5G rollout (Gandotra and Jha 2016; Tehrani et al. 2014). 5G is proposed to present a communication standard beyond 4G/IMT-Advanced, referred to as "IMT-2020" (Shen 2015). Current research for 5G focuses on the need for higher capacity, low end-to-end latency, higher data rates, lower cost, more efficient energy consumption, massive device and machine connectivity for IoT, better QoS, and improved user experience.
