Abstract
Method and apparatus are disclosed for wireless backscatter with time-of-flight for vehicle communication. An example vehicle includes a communication module for Wi-Fi communication and a controller. The controller is to send a signal via the communication module upon identifying a passive-entry passive-start (PEPS) request and receive a backscatter signal from an electronic device. The backscatter signal is a reflection of the signal. The controller also is to determine a distance to the electronic device based upon the backscatter signal and perform the PEPS request upon determining the distance corresponds with the PEPS request.
