BLE Beacons are small BT beacons that emit a signal at periodic intervals. Due to their UV-resistant housing material they can be used both, indoors and outdoors. The beacons can be mounted directly on a suitable surface or easily adapted on the optional available mounting plate (which facilitates the battery exchange of the beacons). The Bluetooth 4.0 standard makes the beacons compatible with currently popular smartphones & tablets and they can be recognized by such devices over a distance of up to 200 m (Geolocation). The beacon signals can be evaluated by the mobile device via individual applications and, in this way, interact with the user or other programs.
