Basically, is 5G technology going to bring a true end to limited unlimited data rates and throttling horseshit? Will it finally be like wired internet where you have realistically, "unlimited" internet? Canadians not withstanding.

Idk man, i have unlimited non-throttled data on 4G already. I have since like 2015. It's not even an expensive plan. So wtf?

I've found that I can't get a signal in certain buildings.

No, because that's only there now to wring more money out of customers. They will do that until they are no longer legally allowed, and that's not going to happen any time soon.

This,

It will only stop when there is real competition, which is bound to happen eventually. I'll bet that in about a decade there will be Chinese companies providing 7G service to any city above 2mil, at 1GPS symmetric no less.
Of course their competition (from India) will provide it at half the price. But western quasi monopoly ISPs, never.

Don't believe me? Just look up how China is building 80% of infrastructure in fucking Africa right now.

>How?
I want high speed internet that isn't fucking tethered in some way to a building. All the cell plans in my area are "unlimited" but only about 5gb is unthrottled. Then it goes to dialup speed without wifi. Of course you can buy 5 more gb for 10 dollars tacked onto your bill.

The communication network is a vital resource. It should only be built and maintained by domestic companies, as a matter of national security.

Agreed, it's a bittersweet realization.

Any way, from a technical perspective the whole wireless business is a bureaucratic clusterfuck. Because of military and government paranoia and apathy frequencies for civilian radio communications are severely restricted.
If it weren't for that we would have got wireless (not mobile cuz of power) Internet in the early 2000s.

This is also part of the reason why mobile Internet sucks so much, companies gobble up rights in the frequency band and essentially squat on them, without really using it. It's some twisted analog of the real estate bubble or NYC taxi licenses.

Sorry, it doesn't work that way. One could I guess tether to their smart phone,
after a certain amount of data is passed it will be throttled. Unlimited data,
speeds, doesn't mean is going to happen. Gotta pay, $$ for.

Other countries are required to give people real fast internet. Building codes
require new construction to have high kick speed internet. Right wingers
fight against this, while even third world countries get fast internet by default.

First: 5G is NOT a replacement for 4G, at least not the exciting part.
"5G" that you can be used on your phone using the existing infrastructure is essentially 4G technology.

The exciting part is ulta-high frequency radio, also called millimeter waves.
They are frequencies between 24-86ghz and their wavelength is as the name suggests ridiculously small.
This high frequency enables the massive bandwidths (essentially like fiber along with it's low latency).

The problem is two-fold:
  1. Absorption through the air becomes significant requiring the client and station to be very close together.
  2. It absolutely has to be line-of-sight, windows, tree leaves and even your fingers completely bock millimeter waves.

So this leaves it as a replacement for traditional broadband ala cable, dsl or fiber.
This would work by having a repeater on your window that receives 5G on the outside and wifi/5G/ethernet on the inside. Links would be semi directional. This is potentially cheaper than fiber and almost as good.

To actually use 5G mm wave in mobile you'd need something like a station in every other streetlight fixture. Your mobile device (no it won't be a phone, no matter what you don't need several gigabits on your handheld device).
But lets say 20 years from now augmented reality finally takes of.
You would have some sort of hat that is plastered with solid state transceiver arrays and lidar chips. The device would use beam-forming to connect to the nearest peers and stream gigabytes of point-cloud data back and forth.
