The next generation of cellular technology will make vast improvements in bandwidth utilization, data delivery, and application enablement. 6G is expected to offer download speeds approaching one terabit per second, microsecond latency, and unlimited bandwidth.

6G will enable creative ways for people to interact with their environment, including instant communication, connected robotics, autonomous systems, and wireless AI interactions.

Keysight 6G Program Manager Roger Nichols answers questions about the technological advances needed to enable the 6G vision.

Q: What will 6G do for us?

A: 6G will go a step further than 5G in integrating communications with computing, so that network as a service (NaaS) and computing as a service (CaasS) become seamless.

A: 6G will go a step further than 5G in integrating communications with computing, so that network as a service (NaaS) and computing as a service (CaasS) become seamless.

This requires the use of advanced communications to allow compute to be distributed between the cloud/centralized, Edge, and client in a flexible way to optimize based on use case, business, and environmental considerations.

Expansion into new use cases in government, business, healthcare, and education will generate profits by using new capabilities in 6G to do what previous generations of communications technology couldn’t.

For example, better resource-centralized blended education with higher commitment, flexibility, and reduced latency can be a result.

More efficient transportation of goods and services with automated supply chain management in communications and computing, global positioning systems that use AI to help anticipate needs, reduce waste and address emergencies; can be another

By combining advanced communications and location information with advanced sensing and distributed computing, mechanical automation becomes more sophisticated. Cooperative robotics will enable automated transportation, as well as play an essential role in manufacturing, construction, mining, and emergency management.

Immersive telepresence could combine 3D haptic holography and computing to provide real-time automated language translation for teleconferences, or integrate a haptic hologram with a digital twin and a physical system for remote training or troubleshooting.

Q: How can use cases like these be produced?

A: New use cases require development in technology, business models, policies, and even social interaction.

The technologies involved will need to handle much higher data rates, further reduce latency, deliver predictable sub-millisecond times, expand the density of data devices/users it can handle, and seamlessly integrate wireline, point-to-point microwave, terrestrial cellular , satellite, Wi-Fi, PAN (Bluetooth), NFC and other types of networks.

The network will need to become more reliable and resilient, as more pervasive use cases mean it will be used by applications for which the stakes are higher in terms of society, security, business risk, and environmental impact.

New software technologies will be needed for distributed cloud, edge, and client computing, while improvements in AI will be combined with computing to optimize system performance for use cases. And the resource efficiency of systems will need to improve, with particular emphasis on power and spectrum.

Significant improvements in cybersecurity applied to mobile wireless systems will be needed to address a vast expansion of use cases and threat surface, and an increase in system risks.

Q: How does 6G support the growing Internet of Things (IoT)/Internet of Everything (IoE)?

A: As suggested, the flexibility and capacity of the network combined with distributed computing and sensing systems, some may even be embedded in people, means a more seamless interconnection of our various communications technologies.

In 2016, Mischa Dohler of Kings College London (now with Ericsson) taught a class on IoT in which she stated, “We don’t really have a Internet of Thingswe have one internet of things” (or rather, various intranets of things).

What he meant by this was that the value of IoT (and ultimately IoE) is not just the interconnection, but also the use of the resulting data in beneficial and secure ways.

Most IoT systems do not communicate with each other or share data to harness knowledge (such as between a parking management system and a traffic management system). This type of communication does not take place or is quite difficult and time consuming.

So a required breakthrough in 6G has almost nothing to do with the radio link, but much more to do with how the information in the system can be harnessed.

By merging sensing, communications, and distributed computing into a larger programmable network, we can harness technology in more comprehensive ways.

Q: What is the 6G specification roadmap?

A: Assuming that 3GPP remains the de facto set of specifications for a global standard, we can expect the first work on 3GPP specifications to start around 2025. Some people claim that the first implementable 6G features will come in version 21.

That said, there are two other things to keep in mind. First, 3GPP is not the only specification body that will contribute to 6G. Changes will need to be made by the IETF, various parts of ETSI, and O-RAN.

However, for things to become standardized, a lot of work must be done to develop and test the technological advances that are needed to make the vision a reality; Not only is the list long, but each item has many levels of complexity and will require innovation across the board. those levels.

This means that standardization cannot really begin until we are more confident in our ability to deliver the required technologies.

Q: Where is Keysight positioned in 6G and what is Keysight’s goal?

A: Keysight builds tools for design and measurement from research to manufacturing to deployment to operations, and from the physical layer to the application layer, including security, digital twins, and our own growing use of AI.

Therefore, we are in a position to provide the tools for technologists to optimize their designs, model them before implementation, assess how well their designs and systems work, and make tweaks and upgrades to further optimize functionality and performance. Our job is to provide the tools the wireless communications industry needs to turn the 6G vision into reality.
