Re: Pretty sure you can't change the laws of Physics...
The laws of physics don't change. That's why your radio receives one channel, just Morse code. After all, the first radio experiments worked that way, and the physics isn't any different today. The advantages are in our more efficient use of the laws of physics. Instead of using all frequencies, we limit to a smaller band. Instead of using analog data, we use digital data which can be more tightly packed. Some of the changes are redesigns like that, whereas others are simply improvements in manufacturing technology allowing transmitters to use less bandwidth while not getting prohibitively expensive. The laws of physics say such things as how much power your signal will have based on the distance and items between the receiver and transmitter, that is unless you use other physics hacks like finding a way to reflect it, but those laws say nothing about how low the power level can get before your receiver can no longer use it, let alone how many bits per second you can manage to shove in there. That's down to your tools, and those do change.
As for WiFi, you can have that. Lots of countries have some ISP who came up with this idea and has a public access method. Find which ones do that in your country, they probably exist, and sign up for an account. Congratulations, you have WiFi access from the house of anyone who has the same ISP and didn't change the settings on the supplied equipment. It doesn't work for people like me who buy my own equipment and configure it myself, but my neighbors have these, so you'll have coverage. That is you'll have coverage when you're near someone else's house, but I spend no effort making sure my WiFi coverage extends outside those walls very far. If you're in the street near a house, you'll probably have something, but if you're in a more open space, you won't. The same applies if you're moving between these access points. Most importantly, there are a lot of places without houses where you won't have any APs to connect to at all, and if you want the internet there, you'll need something that has better coverage than home WiFi.
