Abstract
A portable device is configured to establish a Bluetooth low energy (BLE) communication connection with a vehicle and to communicate with at least one sensor in the vehicle using impulse radio (IR) ultra-wide band (UWB) communication after establishment of the BLE communication connection with the vehicle is completed. A location of the portable device is determined by the vehicle based on ranging using IR UWB communication performed by the at least one sensor.
