Abstract

A technology for a wireless transfer station that is operable to wirelessly provide energy to other wireless transfer stations. A wireless transfer request can be received from one or more of the other wireless transfer stations to receive wireless energy from the wireless transfer station. A transferring of wireless energy to the one or more of the other wireless transfer stations can be prioritized using selected energy transfer priority criteria. Wireless energy can be provided to the one or more of the other wireless transfer stations based on the prioritization.
