What is an iBeacon and how does it work?

This is the name given to a technology used indoors. The name "beacon" comes from English and means "light signal." This technology is used as a navigation method between an app and a radio chip. The connection between these two functionalities is established using Bluetooth Low Energy (BLE). To determine the location of the mobile device where the app is installed, signals are sent between it and the stationary radio chip at regular intervals. In short, this is a Bluetooth station for "checking in" on site.
