OK kiddo, let me explain 802.20 to you. You know how you can use your tablet or phone to watch videos and play games, right? Well, what if you wanted to use your tablet or phone in a moving car, train or bus? That can be tricky because the signal for the internet can get weak or even disappear when you're moving. That's where 802.20 comes in.
802.20 is like a special highway just for internet signals that can move with you. It's called a wireless network, which means you don't need any cables or wires to get online. It works a bit like a walkie-talkie, where one device talks to the other without wires.
The cool thing about 802.20 is that it can work even if you're moving fast, like on a train. It uses special technology called "handover" that means you can switch from one cell tower to another without losing your internet connection.
This is really important for people who live in areas where there aren't many Wi-Fi hotspots or where the signal is weak. It means you can use your tablet or phone to watch videos and play games wherever you are, even if you're moving.
So, that's what 802.20 is all about. It's a special highway for internet signals that can move with you, so you can stay connected wherever you are. Pretty cool, right?
