IEEE 802.20
Alright kiddo, let's talk about IEEE 802.20. This is a fancy name for a set of rules that help people use wireless communication better.
Think about it like this: you know how when you want to talk to your friend across the room, you have to yell really loud so they can hear you? But if you had a phone or a walkie-talkie, you could talk to them without having to yell? That's kind of like what IEEE 802.20 is all about.
It helps people use something called "wireless broadband" to talk to each other over long distances, without needing to use cables or wires. This is really important, because it means people in different parts of the world can talk to each other and share information really easily.
So, how does it work? Well, imagine you have a special walkie-talkie that can talk to other people's walkie-talkies, but it needs a certain kind of code to do it. That code is kind of like a secret handshake - only other people with the same kind of walkie-talkie and code can talk to you.
IEEE 802.20 sets up some rules for how to use these secret codes, so that everyone's walkie-talkies work together smoothly. It also sets up rules for how to share the "airwaves" - the space in the air where the wireless communication happens - so that too many people aren't trying to talk at once and making things all jumbled up.
Overall, IEEE 802.20 is like a rulebook to help people use wireless communication to talk to each other better and more easily, kind of like a fancy game with its own set of instructions.
