How to Improve 5G

What if there was a way to improve 4G or even 5G, the way our phones communicate with cell towers. I was looking into how we've expanded the way we store data on our phones via a sim card. The quantity keeps increasing because of the new methods to read data based on an example provided to me to "Measure data similar to how a glass holds water" each glass represents a binary of data. If we begin to expand the value read by these glasses (glass a quarter full or even an eighth full) we increase the memory availability of our devices.

So this got me thinking. What if this could be carried over to data transmission? What if instead of measuring the voltage of certain data points and splitting it up, we set up our phones to receive data on a mode that alternates every bit into 800 MHz and say 801 MHz. Our phones can now say this 800MHz represents an additional 0 and this 801MHz signal now represents a 1 and we can shove the on and off signals on the inside of each wavelength. Any thoughts?
