Abstract
The technology described herein relates to techniques for calibrating wireless power transmission systems for operation in multipath wireless power delivery environments. In an implementation, a method of calibrating a wireless power transmission system for operation in a multipath environment is disclosed. The method includes characterizing a receive path from a calibration antennae element to a first antennae element of a plurality of antennae elements of the wireless power transmission system, characterizing a transmit path from the first antennae element to the calibration antennae element, and comparing the transmit path to the receive path to determine a calibration value for the first antennae element in the multipath environment.
