Abstract: A data transfer method for autonomous vehicles includes autonomously positioning a vehicle to achieve an alignment condition in which a vehicle-mounted directional antenna coupled to a vehicle radio is aligned with a curbside antenna coupled to a curbside radio. A peer-tip-peer radio link is established between the vehicle radio and the curbside radio, and data is transferred from the vehicle radio to the curbside radio using the peer-to-peer radio link. The peer-to-peer radio link may be a millimeter-wave radio link. Data is transferred at high speed, for example at least tens of gigabits per second or even hundreds of gigabits per second. The vehicle may be an electric vehicle, and electric charging of the vehicle may be performed while transferring the data. In one embodiment, the vehicle is configured to proceed to a recharging location when a given low state of charge is reached.
