CdmaOne

Okay kiddo, have you ever played with walkie-talkies before? When you push the button to talk, it sends a message to whoever you want to talk to through the airwaves.

Well, mobile phones do something similar. But instead of just sending messages to one person at a time, they need to talk to lots of different people all at the same time.

This is where CDMA comes in. CDMA stands for Code Division Multiple Access, which basically means that each phone has its own special code that allows it to talk to lots of other phones all at once without getting mixed up.

Think of it like a secret language. Each phone has its own secret code, so it knows who it's talking to and who is listening, even if lots of other people are talking at the same time.

So when you make a call on a CDMA phone, it uses its secret code to talk to the other person's phone, and they can talk back using their own secret code. And because everyone has their own code, nobody else can listen in on your conversation - it's like having your own private channel.

CDMA was the first type of mobile phone technology to use this kind of secret code system, and it's still used by some networks today.
