Imagine your smartphone is like a detective trying to find you. It uses clues from different sources, like the GPS satellites in the sky and the Wi-Fi networks around you. If it can’t see the sky, it asks nearby cell towers for help. The more clues it gets, the better it knows where you are, just like a detective solving a mystery.
Examples
- Your phone knows you're at the park because it sees a familiar Wi-Fi network there.
- If your phone can't see the sky, it asks nearby cell towers for help finding where you are.
- You lose your way in a mall, and your phone uses known Wi-Fi signals to guide you back.
