Indoor positioning is like using a GPS inside a building instead of outside. It uses technology to figure out where you are inside a building, like a mall or an airport, so you know where you are and can get to where you want to go. To do this, it looks at special signals, like Wi-Fi signals or Bluetooth signals, to figure out exactly where you are. That way, when you look at your phone or another device, it can show you where you are and how to get to where you want to go.
