An exemplary method for indexing transceivers uses wireless ranging functionality. The method includes determining a ranging distance between at least one transceiver and each other transceiver in a plurality of transceivers, determining a transceiver spatial distribution based on the ranging distance between at least one transceiver and each other transceiver in the plurality of transceivers, and indexing each transceiver by applying the transceiver spatial distribution to a spatial distribution map using an electronic control unit (ECU).

Wireless transceiver indexing

A method of measuring a tread depth of a tire includes transmitting at least one radio wave from a transmitter through a tread of the tire. The at least one radio wave reflected from a road surface is received with a receiver. The tread depth of the tire is determined based on comparing the at least one radio wave reflected from the road surface with the at least one radio wave from the transmitter.

A method of operating a communicator includes operating a first receiver of a plurality of receivers on a first channel of a series of channels. A second receiver of the plurality of receivers is operated on a second channel of the series of channels. A third receiver of the plurality of receivers is operated on a third channel of the series of channels. The second receiver that operates on the second channel includes a reception overlap period of about 25% to about 75% with the first receiver that operates on the first channel and a reception overlap period of about 25% to about 75% with the third receiver that operates on the third channel.

System and method for operating a radio frequency system

A system and method include, among other things, providing at least one vehicle transceiver and at least one tire information sensor for a tire on a vehicle and wirelessly communicating between the at least one vehicle transceiver and the at least one tire information sensor via a signal. A phase shift in the signal is determined and a physical distance between the at least one vehicle transceiver and the at least one tire information sensor is determined based on the phase shift. A position of the at least one tire information sensor within the vehicle is then determined based on the physical distance.

A vehicle access system includes an identification device with a first transceiver, a short-range transceiver and a processor configured to control the first transceiver and the short-range transceiver to activate the first transceiver only when a distance measurement between the identification device and a vehicle is within a predefined range as determined utilizing the short-range transceiver.

A method for phase ranging of a personal area network device includes receiving an initial personal area network packet and storing header information contained in the initial personal area network packet. A phase shift is measured utilizing information transmitted in place of the stored header information in at least one incoming personal area network packet. A range of the personal area network device is calculated based on the phase shift of the information transmitted in place of the stored header information in an incoming personal area network packet.
