Press Release of “From 5G to 6G and Beyond: The 7Cs of Future Communications”

Why 6G when 5G is already so fast?
New book explains why with the 7 Cs of Future Communications

Why should countries invest in 6G networks when existing 5G networks are already so powerful? This question might seem irrelevant now, but it will shape the future of countries and businesses.

These days, people are not just accessing digital information in real time but also watching movies, playing games, and enjoying multimedia data streaming services even when onboard airplanes and trains traveling at very high speeds. As human society evolves towards a more data- and network-oriented world, consumers and service providers are seeking more advanced communication systems that offer lower latency, higher bandwidth, and larger data capacities. Hence, efforts are underway to consider beyond state-of-the-art protocols, future chip design and integration, and even standardized guidelines for 6G wireless communication systems.

With wireless connectivity becoming ubiquitous, a future where applications like virtual and augmented reality, artificial intelligence (AI), machine learning and even autonomous vehicles requiring high data rates combined with extremely low latencies, or delays, due to processing time may arrive sooner than we think—if we have the right network architecture to support such a reality. Accordingly, 6G, with its peak data rate of 1Terabit per second and latency of 100 microseconds, should be able to smoothly support these use cases. At the same time, individuals and organisations will expect a trustworthy network that can seamlessly and securely deliver data—meaning that further research must focus on building a holistic 6G network security architecture.

Written by four IEEE Fellows, one Chief Executive Officer, and several leading experts in communications and semiconductors, From 5G to 6G and Beyond: The 7 Cs of Future Communications covers all aspects of future communications from key technologies, design challenges, network requirements and users’ experiences to standardization, chip design and industry applications from 5G to 6G. It demonstrates how two seemingly unrelated technologies in the past can be integrated to create new solutions for the future.
Power consumption is another major consideration when designing future networks. This is because of the current power needs of 5G networks; as explained by Huawei in July 2020 , while the “Energy consumption per unit of data (watt/bit) is much less for 5G than 4G…power consumption is much higher [than 4G networks]”. To address this problem, we must target to deliver the next generation networks that, at their introduction time, does not surpass the previous generation’s energy needs.

Therefore, the next generation of wireless communications and semiconductor technology is expected to work together to meet the energy needs and demands of various challenging use cases that cover a wide range of new applications; from 5G/6G communications, mobile computing, artificial intelligence, and advanced internet of things, to big data, cloud, and edge computing.

From 5G to 6G and Beyond discusses the open problems of future communication systems and chip design, and present new solutions that address these challenges. Specifically, the role of semiconductors in future communications are discussed. The use cases of 6G, the RF transceivers roadmap for 2030 and beyond, as well as the modelling of RF devices for 5G/6G are presented. Additionally, a modified Shannon’s capacity formula that is critical for future advanced wireless communications, is examined for the first time. The standardization of 6G wireless communication systems, with emphasis on Standard Development Organizations (SDOs), regulatory bodies and administrations, ITU, industry forums, and 6G standard timeline, is reported. Finally, the design of RF/mm-wave integrated circuits and systems, which includes voltage-controlled oscillators, power amplifiers, low-noise amplifiers, frequency synthesizers, high-frequency dividers, and chip-to-chip communications isolation technology, is described.

From 5G to 6G and Beyond: The 7 Cs of Future Communications retails for US$118 / £105 (hardcover) andis also available in electronic formats. To order or know more about the book, visit https://www.worldscientific.com/pressroom/2023-04-26-01
