The realistic limits of cellular networking.
(1/1)
msuffidy:
Recently my Bell line was becoming expensive, and went dead, and I came up with the idea of using cellular data with an unlimited plan. I actually save $5 a month now than my former bell home phone + 3rd party dsl. I pay $12 a year to host a website at my former 3rd party provider.

So everything works fine until I get to the data speed limit, then I have unlimited slower speed. I find that if I constantly download things I can use the same data total as I previously did, but it handles pretty slow for live applications.

So recently I was questioning, if everyone wanted to do this, and expected like a 30Mbit connection for example, what are the technical limitations? Is there like a need to have more towers, or is it even possible for everyone to be doing this in a dense location? I am guessing the main problem is the cell tower's fiber data link bandwidth.

I don't understand what incentive there ever was for providers to operate cell towers. The best sense I can make of it is that it is good for spying on people and finding them. It is confusing how different providers have different towers. I turned off roaming because I expect there could be charges.

Also like what is the maximum data bandwidth of RF in general, something like 300Gbit? I mean like there is hdtv, radio, etc in there. I am sure there is an attenuation/range compromise?

I imagine one incentive, albeit perhaps a small one, is to be able to connect to their customers' phones.

You guess correctly although not all towers have a fiber backhaul as some have p-p wireless connections.
This might be a 1 GB/s wireless connection but often is less depending on the HW used and its carrier frequency.

Here in NZ providers manage data connections in various ways, some limit the # of permanent connections while others don't so speeds drop to hell in times of high demand.
