Bluetooth® Low Energy Contactless data communication and mobile
authentication for longer distances up to 10 meters.

A BLE-capable device, e.g. – The BLE-compatible reader smartphone, scans all BLE devices in range and receives information about every possible connection. The BLE compatible reader from ELATEC broadcasts its existence to enable discovery. As soon as the connection between the smartphone and the reader is established and confirmed, the authentication process starts. To improve security during data transmission, the connection can be encrypted; it is also possible to add a complete credential to the BLE connection backend.

BLE-capable devices or beacons can communicate with one another from several (up to ten) meters away. Devices with Bluetooth® Version 5 or later can even reach 50 to 200 meters in ideal cases. This longrange can be harnessed to good effect depending on the usage scenario. Alternatively, BLE units can be set to only detect other units a very short distance away, similar to an RFID transponder.

Thanks to today’s very low power electronics, one single battery typically has enough power to supply a BLE transmitter (beacon) with energy for up to one year (depending on the frequency range and power level).

ELATEC does not currently offer any battery-operated products.

The Bluetooth® Special Interest Group (SIG) organization is a network of participating organizations and companies that maintain, expand and employ Bluetooth® technology.

The SIG maintains and issues usage rights and licenses that allow others to use and deploy Bluetooth® technology.

BLE (Bluetooth® Low Energy) is an extension of the Bluetooth® industry standard. It was first released as part of Bluetooth® Version 4.0 and it is characterized by its extremely low energy consumption. Versions 4.1, 4.2 and 5.0 offer additional extensions and upgrades for the specification.
