The Impending Evolution: Exploring the Promises and Challenges of 6G in Mobile Telephony

Over the past decade, there has been a tremendous increase in the demand for mobile traffic. While fifth-generation (5G) networks are in the initial phase of deployment and have the capabilities to meet the data requirements to some extent, it is essential to start thinking beyond 5G systems. The demand for wireless devices and their applications continues to grow exponentially, presenting significant challenges in delivering reliable services with high speed and low latency. These requirements necessitate the upgrade of wireless mobile networks approximately every ten years. As the deployment of 5G networks is underway in various parts of the world and is expected to be fully implemented by 2030, many researchers have already begun focusing on the vision and requirements for the next generation, namely the sixth generation (6G). This forward-thinking approach is necessary to ensure that future wireless networks can meet evolving demands and provide even more advanced capabilities.

In this article, we will explore the key features of 6G, its potential impact on society, and the technical challenges it faces in implementation.

What is 6G, and How Does it Differ from 5G?

6G is the upcoming generation of mobile communication technology that will succeed in 5G. It will not only build upon the strengths of 5G but also introduce entirely new technological solutions. The applications and requirements of 6G are expected to surpass those of current 5G networks, necessitating a more extensive network capacity. Although still in the early stages of development, 6G is anticipated to bring significant improvements in various aspects. Notably, the connection speed is expected to be dramatically faster, with theoretical speeds reaching up to 1000 Gbps. This ultra-high-speed will enable virtually instantaneous data transmission, revolutionizing how we interact with technology and unlocking new possibilities.

Key Features of 6G

6G is not just about faster speeds. It is also expected to provide advancements in other important areas:

  1. Ultra-low latency: 6G aims to reduce latency to nearly imperceptible levels, with less than one millisecond response times. This will be crucial for real-time applications such as virtual reality, autonomous vehicles, and smart cities.
  2. Increased capacity and connection density: With the exponential growth of IoT devices and the ongoing demand for connected services, 6G will seek to enhance capacity and connection density to ensure a seamless and uninterrupted experience.
  3. Improved energy efficiency: As connected devices increase, energy efficiency becomes crucial. 6G will focus on developing technologies that minimize power consumption and extend the battery life of mobile devices. 6G aims to improve the overall energy efficiency by 100 times across the network

d)Sensing Capabilities: 6G will integrate sensing with communication in a single system, leveraging radio waves to “see” the physical world and create digital twins in the cyber world

e)AI and compute: AI will be used to design, deploy, operate, and optimize 6G networks, devices, and services. The AI-native system will gather information from end to end and utilize dynamically distributed computing to enhance performance and introduce new capabilities in devices, infrastructure, networks, and clouds.

f)Resilience and security: As wireless networks increasingly become critical components of society, the importance of resilience and security capabilities cannot be overstated. These networks must be able to continue providing service even when parts of the infrastructure are disabled due to natural disasters, local disturbances, or societal breakdowns. Additionally, they must possess robust resistance against deliberate malicious attacks to ensure the integrity and reliability of the network.

Impact on Society and Industries

The deployment of 6G will bring about transformative changes in various sectors:

  1. Healthcare: The low latency and ultra-fast connectivity of 6G will pave the way for significant advancements in telemedicine, remote surgery, and patient monitoring. This technology will enable the delivery of high-quality medical services in remote areas, revolutionizing global healthcare. Additionally, 6G will be crucial in providing cost-effective remote services for patients, allowing for home-based care. The network’s capabilities will also extend to handling many patients, addressing scalability challenges. 6G aims to be a supportive network that will realize the true potential of healthcare networks and evolve the human body as an integral part of the interconnected “Net.”
  2. Transportation: 6G will be instrumental in developing autonomous vehicles and creating intelligent transportation networks. The low latency and high connection capacity will ensure instant communication between vehicles, infrastructure, and pedestrians, enhancing transportation safety and efficiency.
  3. Industry 4.0: 6G will support industries’ digital transformation and automation. With increased capacity and connection density, smart factories will optimize production processes, leverage artificial intelligence for decision-making, and benefit from interconnectivity among machines and sensors. These factories, often referred to as the “factories of the future,” have the potential to enhance manufacturing processes by intelligently balancing market supply and demand, predicting maintenance requirements of machines, and enabling remote monitoring through global control centers by large multinational companies. Furthermore, utilizing historically collected data, these companies can intelligently predict the success or failure of product line flows.

Technical Challenges

While 6G promises a technological revolution, it also faces significant challenges in implementation:

  1. Higher frequencies: 6G will utilize much higher frequencies than those used in 5G to achieve extremely high speeds and capacities. This presents technical challenges regarding signal propagation and the construction of suitable infrastructures.
  2. Power consumption: As the number of connected devices increases, power consumption becomes a concern. 6G must address the challenge of achieving higher energy efficiency without compromising performance.
  3. Privacy and security: With the growing amount of data transmitted in a 6G environment, privacy and security have become critical. Robust data protection mechanisms and ensuring network and communication integrity will be necessary.
  4. Localization: The 6G network will require the capability to automatically comprehend user needs and provide precise localization to meet specific use cases by the 2030s. Applications like self-driving cars and robotic surgery will demand high-resolution positioning systems with centimeter-level accuracy. These advanced positioning systems will facilitate precise and accurate location information, resulting in improved application performance and functionality.



As new generations of wireless communication networks are developed, existing technologies are improved, and new features are added to meet future needs. In this regard, 5G technology may not be able to handle the continuously growing communication demands. The emergence of 6G is expected to revolutionize how we communicate, interact with technology, and shape our societies. While widespread implementation is still a long-term goal, the possibilities offered by this next generation of mobile technology are truly exciting. Researchers and engineers are dedicated to overcoming technical challenges and pushing the boundaries of interconnectivity and innovation, positioning 6G as the next significant milestone in the evolution of mobile telecommunications.
