Maybe an ignorant question, but i sat up thinking about it last night.
In: Technology
Cell phones use radio waves to communicate with the nearest cell tower which is connected by cables to the cell tower the person you are calling is nearest.
The interesting part is that there aren’t enough radio frequencies for this to work, so we have to use math to encode as much information as possible in the smallest portion of the radio spectrum. There have been 5 generations of technology to do this which you might be familiar with the last three (3G, 4G, 5G). Each have required more powerful compute power in both the phone and the tower, although 5G also required different radio frequencies so it was more hardware than software based relative to the previous generations.
