Unleashing The Power Of 5G Technology And Role Of AI In 5G Network Management

Introduction

Put to use in the context of 5G network, AI can contribute to optimize network performance and resource allocation, detect and mitigate security threats, and enhance user experience, among other applications.

Network operators can use AI in their network management and optimization processes in various ways. AI systems can analyse data related to network performance metrics, user behavior, and traffic patterns to optimize network resource allocation, predict and prevent traffic congestion, and improve overall network efficiency and quality of service.

AI can also dynamically allocate network resources for different services and applications, ensuring adaptation to changing network conditions and user demands and facilitating efficient service delivery. AI tools can further be used to enable the integration of edge computing capabilities into 5G networks (allowing data to be processed as close to the data source as possible, to reduce latency and bandwidth use) by enabling real-time data processing, intelligent decision-making, and faster response time. AI is also useful for predicting, detecting, and mitigating security threats. For example, AI-powered security solutions are often used to analyse network traffic patterns, identify anomalies and suspicious activities, and help enhance the overall resilience and security of 5G networks.

AI and 5G Network Security Threats

As 5G network continues to be deployed around the world, malicious actors can also leverage AI to craft powerful attacks threatening the integrity, stability, and security of 5G network. AI techniques enable attackers to automate and optimize cyberattacks such as sophisticated malware propagation, evasion of security defences, and targeted exploitation of vulnerabilities in 5G infrastructure. Moreover, the integration of AI within critical components of 5G network introduces new vulnerabilities that opponents can exploit. For example, they can manipulate AI models, triggering erroneous processes that compromise network security and integrity.

What Makes 5G Special?

5G (the fifth generation mobile network) is key to unlocking the potential of AI, the Internet of Things, (IoT), virtual, augmented, and mixed reality, and much more. The extent to which 5G will revolutionize many facets of our lives is akin to the shift from the typewriter to the computer.

What makes 5G special compared to previous generations of mobile networks? It comes down to the differences in speed, latency, and bandwidth. 5G is significantly faster than 4G, delivering speeds up to 10 Gigabits-per-second, while 4G tops out at 100 Megabits-per-second. Practically, 5G will allow you to download a high-resolution movie in 6 seconds at its peak download speed. It will also essentially eliminate latency, enabling virtual interactions, and conversations to be closer to real life.

More importantly, 5G will enable real-time remote control of automated processes (in industrial or smart city environments) that involve sensors and smart devices. Furthermore, 5G comes with increased bandwidth, which allows for greater optimization of network traffic and smooth handling of usage spikes. You’ll experience seamless connectivity even in crowded areas such as concert halls and stadiums. 5G will allow billions of smart devices around the world to connect and interact among themselves, and with us.

5G Infrastructure

The infrastructure of 5G will look significantly different from past generations. 5G network infrastructure allows signal processing power to be moved away from transmitting ends and further into the cloud. Essentially, 5G networks can be virtualized and will open up wider market competition, as this virtualization enables the use of end-equipment that are less technologically advanced and software solutions to operate a network. The market for 5G network infrastructure will include not only traditional telecom equipment vendors (e.g. Huawei and Ericsson), but also software-based companies such as Rakuten and Microsoft.

Benefits of 5G Network

First and foremost, 5G will enable IoT to reach its full potential. It will not be limited to smartphones and tablets. Industrial sensors, wearables, medical devices, and vehicles will all be connected to the Internet once 5G networks are widely available. Factories will be “smart” in the way that each sensor that collects and uses data will optimize production line efficiency, reduce energy consumption, and enable time-sensitive operational process controls. In smart cities, AI will adjust traffic signals and traffic flows by conducting video analytics to minimize the time cars idle at red lights, which can save time and frustration while helping reduce air pollution.

With the significantly reduced latency of 5G, virtual reality (VR) will be highly relevant in the field of medicine. For example, surgeons will be able to perform remote surgery by using a VR headset and a special glove to control a robot arm that performs an operation in another location. Teleconferences, which have become a new norm for office workers after COVID-19, will also offer a closer-to-real life experience as people will experience fewer dropped connections, better video quality, and ubiquitous mobility.

The Broader Context of 5G

The advent of 5G comes with edge analytics, a new model of data analysis, in which data processing occurs at a non-central location such as a device and sensors. Traditionally, AI has been equipped in the cloud; however, it will be fully distributed to each device and sensor to conduct data analysis. In theory, this approach enhances privacy and reliability because the data processing is conducted closer to the source.

Techno-nationalism is not new, but has escalated with 5G. Many countries are racing to develop and deploy 5G networks because of the following two assumptions:

(a). An early technological lead grants countries a first-mover advantage; and

(b). Dominance in certain technologies grants them an edge in other fields.

The ongoing confrontation between the United States and China is a prime example that illustrates how the world’s large economic and military powers see 5G as critical for the control of their economies and national security. 5G diplomacy based on uni- and bilateralism can lead to a fragmented world.

The Eurasia Group has warned that a bifurcated 5G ecosystem will increase the risk that the global technology ecosystem separates in two parts that are politically divided and potentially non-interoperable.

How 5G Will Transform Military Capabilities?

5G technology will transform military capabilities by:

1). Improving intelligence;

2). Surveillance; and

3). Reconnaissance (ISR) systems and processing, enabling new methods of command and control (C2) and streamlining logistics systems for better efficiency.

The low latency communication on 5G network will also enable unmanned and autonomous weapon systems.

Security Vulnerabilities

The virtualization of 5G brings a new set of security vulnerabilities to the fore. As 5G infrastructure becomes more virtualized (i.e. detached), moving from signal processing at specific and complex transmitting ends to processing software in the cloud, the vulnerability of the cloud and underlying systems introduce vulnerabilities to the 5G network as well. In previous generations of mobile networks, specific hardware by specific vendors would need to have been targeted by specific attacks to exploit vulnerabilities.

As more and more devices and sensors are connected to the Internet and become integral to many aspects of our lives such as water supply, traffic lights, and autonomous vehicles, the security of 5G is no longer just a technical issue but an economic, political, and trade issue. Protecting 5G networks from malicious attacks will become even more challenging due to exponential growth in the number of connected devices and large bandwidth inherent to the network. It highlights the importance of enforcing security standards for IoT devices because unsecured and/or compromised devices will lead to network breaches and hacking.

Lack of Transparency

Just like 3G and 4G, a lack of transparency continues to be an issue with 5G, but to a greater extent. The amount of data that travels through current broadband networks will drastically increase with 5G. As more and more devices will be connected to 5G networks, the amount of data that travels through networks will exponentially grow, which makes it extremely difficult to detect suspicious activity.

Though no concrete evidence has been discovered yet, surveillance and espionage are key security concerns regarding 5G to nation states. In 2012, the U.S. raised the potential risk of espionage by foreign adversaries through telecommunications infrastructure. Since then, trust has become an integral element to take into consideration in the procurement and deployment of equipment to build future generations of telecommunications networks, and even more so with 5G.

To ensure the security of telecommunications networks and avoid equipment manufactured by untrustworthy suppliers, the EU and NATO agreed on a 5G cybersecurity framework, called the “Prague Proposals”. Additionally, the EU released its 5G Toolbox to identify a possible common set of measures which can mitigate the main cybersecurity risks of 5G networks and ensure a coordinated approach among its member states. In the London Declaration, NATO and its allies showed their commitment to ensure the security of 5G communications and recognized the need to rely on secure and resilient systems.

While governments seek to diversify vendors of 5G equipment, manufacturers aim to offer transparency. For example, Huawei opened its Cyber Security Transparency Center in Brussels and Oxfordshire. However, it’s questionable to what extent transparency centers are useful because of limitations such as the level of openness to code, available time, and depth of inspections. The UK government’s Huawei Cyber Security Evaluation Center Oversight Board confirmed such limitations in its 2020 annual report. The Board stated that through its inspection, it can provide only limited assurance that all risks to the UK’s national security by Huawei’s involvement in the UK’s critical communication infrastructure can be sufficiently mitigated long-term.

5G and Trade and Economics

The market of mobile network infrastructure is competitive. The three major players are Huawei, Ericsson, and Nokia, which own 80% of the market share in 3G and LTE networks. With 5G networks being rolled out globally, these three companies remain the most powerful. Out of 239 5G deals across the world, Huawei won 38% of contracts, Ericsson 34%, and Nokia 28%. Huawei’s edge in the 5G market lies in its 1500 patents on 5G-related technology. When combined with patents by ZTE, 36% of all 5G patents are owned by Chinese firms.

As mobile networks have evolved, the supply chain has become more complex than ever, with software and hardware components being manufactured all over the world. As techno-nationalism continues to rise, governments are attempting to place restrictions on access to key components that are manufactured by unfavorable foreign vendors. However, such measures can end up adversely affecting the market for all by slowing down competition and increasing costs.

To accelerate the development and deployment of virtualised 5G networks, service providers established the Open Access Radio Network (O-RAN) Alliance in 2018. The O-RAN Alliance’s open interface will allow small vendors to launch their own services and allow operators to customise their networks. The alliance was founded by AT&T (USA), China Mobile (Tawian), NTT Docomo (Japan), Orange (France), and others. While the O-RAN Alliance represents an alternative for countries that boycott Huawei, its open architecture 5G networks would be still built on Chinese patents with royalties being paid to Chinese firms, even should the networks be equipped entirely by vendors from the USA and its allies.

Banning and dismantling certain vendors’ equipment is costly. In the U.S., it has been estimated that it would cost $12 billion to bar Pentagon and NASA contractors from using Huawei and other Chinese technologies. The EU would need to commit additional €55 billion to build 5G networks without Huawei, which would delay the roll-out by 18 months. Moreover, the UK’s decision to phase out Huawei’s equipment will cause a delay of 2 to 3 years, costing approximately £2 billion.

In the U.S., for example, users are already eager to make the switch to 5G home internet due to faster data transfers, and low costs of equipment. In contrast to developed nations, developing countries may struggle with initial investments in building 5G-ready infrastructure. Telecom firms in Africa can’t launch full 5G services until each country holds a spectrum auction; they also need to build a network of masts or antennas to transmit signals, which will be an expensive investment. Little interest from customers doesn’t incentivize companies to invest, as customer priorities seem to lie in affordability, rather than speed. For example, more than 40% of Nigerian mobile Internet users use the cheaper, but slower 3G network even though the country has an extensive 4G network.

How Does 5G Technology Affect Human Health?

5G technology achieves a significant increase in data transmission rates compared to previous generations by using a higher transmission frequency. 5G will use a frequency band between 700MHz to 6GHz which is somewhat wider than that of 4G, but will also use frequencies at significantly higher windows, ranging from 26GHz to 71GHz, with variation from country to country. The electromagnetic frequency of 5G is non-ionising, meaning that it can’t change atomic structure like x-rays do.

As per the World Health Organization (WHO) no adverse health effects have been causally linked with exposure to wireless technologies. However, only a few studies have been carried out at the higher frequencies that are used by 5G. The WHO is also expected to publish a health risk assessment from exposure to radio frequencies, including the 5G radio frequency range. Such a study can play an important role in debunking mis- and disinformation on 5G. In early 2020, fake news on 5G spread across social media platforms. There were false claims that 5G weakens the immune system and makes people more susceptible to COVID-19 and that the virus could be transmitted through 5G networks. These claims lacked any scientific evidence, but some of those who believed it took to the streets and torched masts in ten European cities.
