In case you haven’t been paying attention, wireless vendors are busy working towards the introduction of 6G starting around 2030. The industry has introduced a new generation of cellular technology every ten years since the first 1G network was introduced in 1981.
I’ve been reading a lot of industry press on the upcoming 6G generation of cellular. I have to admit that some of the claims gave me a good laugh, because the vendors in the industry are touting a lot of potential applications for 6G that seem to be a stretch, just like happened during the lead-up to 5G.
Before describing a few of the promises I’ve been reading for 6G, let me remind you of some of what we were promised with 5G that never really materialized. 5G was touted to be bringing:
- A superfast network since 5G will enable clusters of 5G small cell sites that will bring the network close to everybody.
- Super-low latency of 4 milliseconds, even in moving vehicles. It was promised that 5G would be able to compete with fiber for functions like real-time gaming and stock trading.
- Speeds up to 10 Gbps by the widespread introduction of frequencies between 20 and 60 MHz.
- A greatly increased capacity for simultaneous connections that would mean 5G subscriptions for cars, smart watches, and the many 5G-enabled smart devices in the home.
- 5G would enable new technologies like stores having 5G-enabled hologram displays throughout a store. Experts envisioned a 5G network strung along every street and road to enable smart self-driving cars. There was even talk about being able to use 5G to enable medical operations using robots conducted by remote doctors.
The coming introduction of 6G also includes a lot of claimed benefits. 6G will:
- Enable immersive communication and human-machine interactions. Use cases include immersive eXtended Reality (XR), remote multi-sensory telepresence, holographic communications, haptic sensors and actuators, and multi-sensory interfaces.
- Lower operator costs will mean affordable and meaningful connectivity for all. This means universal coverage, including sparsely populated areas. 6G will create a seamless interface between terrestrial and non-terrestrial networks.
- Be able to connect to a massive number of devices that will enable smart cities, smart cars, environmental monitoring, and sensors for agriculture. (Sounds like the same claim made for 5G).
- Will enable connections to smart machines for the remote operation of robots, autonomous factories, and the creation of digital twins for factories, health care, and other complex use cases.
- Peak data rates between 50 and 100 Gbps.
- A target air interface latency between 0.1 ms and 1 ms.
- Terrestrial-based locating technologies to locate objects within 1 to 10 centimeters.
- AI-related capabilities to support distributed data processing, distributed learning, AI computing, AI model execution, and AI model inference.
Just like with 5G, the real-life implementation of 6G will be determined by the functions that wireless carriers can monetize. 5G is outperforming the hype in some areas, and most urban 5G networks today are considerably faster than the 100 Mbps goal included in the early 5G hype, yet most of the promised 5G functionality never materialized when carriers found that customers prefer free WiFi to paying for more cellular subscriptions. The same is going to be true with 6G. It’s hard to imagine that introducing 6G will automatically trigger widespread use of multi-sensory telepresence or somehow bring cell towers to rural America. But you can’t blame the vendors who want to get carriers excited about 6G and be willing to pay for the upgrades.
