Abstract
A method of RF power delivery includes, in part, transmitting a first group of RF signals having a first group of phases to a first mobile device during a first time period. The first mobile device has a first position and a first orientation during the first time period. The method further includes, in part, transmitting a second group of RF signals having a second group of phases to the first mobile device during a second time period. The second group of phases are determined in accordance with a second position and a second orientation of the first mobile device during the second time period. The second position and second orientation are determined using sensors disposed in the first mobile device and transmitted via a wireless communications channel to an RF power generating unit transmitting the first and second group of RF signals.
