Technology can turn something we have come to known on its head without changing its core premise. Beacon is a kind of like a lighthouse, it repeatedly transmits a single signal that other devices can see. Instead of emitting visible light, though Beacon broadcasts a radio signal that is made up of a combination of letters and numbers transmitted on a regular interval of approximately. A Bluetooth-equipped device like a smartphone can see a beacon once it is in range, much like sailors looking for a lighthouse to know where they are. Beacons are at least as old watches: eye-catching constructions that offer information and navigation on land and at sea. Thanks a lot to the Beacon provider.
