Abstract:
Systems and methods for leveraging multipath wireless transmissions for high data rate communication and charging devices within multipath vehicle environments are described. The techniques include deploying a wireless charger, including an array of antennas, within a vehicle interior. The wireless charger may detect an incoming signal from a client device. Each antenna in the array may determine an offset for the received signal, which is then used to tune parameters for each antenna individually. Upon transmission, the resulting signal is directionally biased toward the least lossy pathways between the device and the charger. These pathways avoid passengers and other sources of signal attenuation. Thus, for a given total power envelope, a greater total signal amplitude may be delivered to the device, with reduced exposure to any occupants of the vehicle. Additionally, the interior of the vehicle may be provisioned to help improve multipath focusing of transmissions.
