"Yes, but this G goes up to 11"
Surrey University has scored £11.6m in government cash, and £24m from the industry, to fund the development of next-generation telecoms in a shiny new 5G Innovation Centre. The government money comes from the UK Research Partnership Investment Fund, by way of the Higher Education Funding Council, but the bigger portion comes …
Unfortunately they are not really compatible with the idea of "network operators".
This wouldn't be much of a problem if it could be completely meshed. However it's likely you need some sort of infrastructure to support the mesh.
What could work, would be to operate that infrastructure by non-profit organisations. Kinda like the "Bürgernetzverein(e)" in the 1990s in Germany. You join them and help them pay the bills and volunteer, while everyone can use it. The more people join the better the network will be.
Poor battery life in mesh networks is a common fallacy, even amongst those that should know better. It was one of the main reasons a mesh option was dropped from the 3G spec. With a fair routing algorithm, each user's power consumption is lower on average. This is because path loss is proportional to distance to a power (i.e. not linear), so the sum of the power consumption of many short hops is a lot less than one big one.
1G used analogue variation in power to transmit calls
2G used digital signals to transmit calls
3G used IP packets to transmit data
4G used vague handwaving to transmit marketing bullshit
5G will use nuclear physics to actually manipulate inter-atomic bonds to send data at almost the speed of light between copper atoms. Billions of these copper atoms will be contained in a new atomic metalic fibre only slightly thicker than an optical fibre and be connected directly to each handset in what the makers a re calling cord-to-handset technology.
"Long-Term Evolution (LTE) radio access is reaching the limits of Shannon's law, the spectrum available for mobile data applications is limited, and the only solution for increasing overall mobile network capacity is to increase the carrier-to-interference ratio while decreasing cell size and deploying small cell technologies"
