Abstract: An apparatus includes a first wireless communication node, a second wireless communication node, and a sensor. The first wireless communication node is operable to transmit a low-frequency wireless signal. The second wireless communication node is in communication with the first wireless communication node and is operable to transmit a short-range wireless signal. The second wireless communication node is operable in an ON mode and an OFF mode. The sensor is in communication with the second wireless communication node and is operable to sense a movement of the apparatus. The second wireless communication node is operable to switch from the OFF mode to the ON mode in response to the movement sensed by the sensor.

Abstract: A method of provisioning car access in a vehicle includes establishing, at data processing hardware, a secure connection between a production tool and more than one low energy communication node of the vehicle. The method also includes acquiring, at the data processing hardware, communication node information from the production tool regarding the more than one low energy node of the vehicle, the more than one low energy node having at least one main node and at least one satellite node. The method further includes communicating, from the data processing hardware, the communication node information about the at least one main node and at least one satellite node, and determining, by the data processing hardware, a mounting location of the at least one satellite node according to signal characteristic data of at least one low energy signal data packet from the at least one satellite node.

Abstract: A method for determining a location of a vehicle access device relative to a vehicle is disclosed. The method includes receiving, at a first communication node of the vehicle, an advertisement from the vehicle access device, and transmitting a connection request to the vehicle access device associated with the received advertisement. The method includes establishing, at the first communication node, a connection with the vehicle access device, and determining a general location of the vehicle access device. When the general location of the vehicle access device is less than a threshold distance, the method includes transmitting, from the first communication node, a high duty cycle advertisement command to a second communication node in communication with the first communication node. The method includes receiving, at the first communication node, a signal from the vehicle access device, the signal indicative of a location of the vehicle access device relative to the vehicle.
