What is 6G and 7G connectivity?

PHILADELPHIA – While 5G networks are still being rolled out around the world, some people are already looking beyond. Telecommunications companies have begun to develop the next generation of mobile connectivity, causing talk of 6G and even 7G networks.

By the end of 2020, there were only 217 million 5G subscriptions worldwide, according to a study by Ericsson. Still, innovators and eager consumers have set their sights on 6G and beyond. While these networks may still be years away, they are likely to have significant implications for technologies such as autonomous vehicles.

What is 6G? The short answer is that this is the next generation of mobile networks, just as 5G was successful in 4G and 7G will also come after 6G. Just as 5G offers higher speeds and lower latency than 4G, 6G promises improvements over 5G.

The appearance of these improvements is less certain. Samsung has proven its possibilities. In June, he said researchers reached speeds 50 times faster than current 5G – 5.23 gigabits per second. With further development, 6G could provide even faster speeds in some areas.

6G networks are likely to work differently than 5G. As the illustration on this page suggests, 6G could use short-range reflected signals to dissipate to nearby connected devices. This would support more devices in an area than the more direct 5G signals, with lower latency.
