Bluetooth Low Energy (BLE) is a wireless personal network technology. It connects a mobile device with a stationary one using the same radio frequencies as classic Bluetooth. However, BLE uses a simpler modulation system than classical Bluetooth. In addition, it also has a much lower energy consumption.
BLE is used in devices that exchange a small amount of data periodically, such as proximity sensors, heart rate monitors, and fitness devices. In addition to such devices, technologies that are used to develop keyless entry to cars also operate via BLE.
Lincoln’s Phone As A Key uses Bluetooth Low Energy (BLE) for the near-vehicle access and start functionality. According to Lincoln, the BLE connection works even when there is no mobile network signal, for example in an underground parking garage. Remote features such as lock, unlock and start from a distance use the embedded modem or Wi-Fi when available.
