The next frontier of Cellular technology is 6G, expected to officially launch in the year 2030. The technology is not developed independently but as a part of a global collaboration but with regional leadership and competition.

Improving from the 5G technology with terahertz frequency range as the operating frequencies. The increase in the bandwidth as a result creates vastly higher data rates that are exponentially faster than 5G potentially reaching terabits per second.

6G isn't the same as Wifi6 as a by the way,

With instantaneous downloads, ultra-HD streaming, 6G technology would offer a much needed reliability on the internet to perform intricate tasks such as surgery over the internet. Holographic communication would change how human beings relate to each other, people would feel potentially more connected to each other, express themselves for both good and bad.

The work structures could change with many jobs being done from home, some industries could have adjusted work weeks and that would also change the other relationships since people would need to find what to do with the extra free time. AR/VR could revolutionize gaming/ the entertainment industries.
