Optimizing pairing of a wireless power transmission system with a wireless power receiver client
Described herein are embodiments of apparatuses and methods for optimizing pairing of a wireless power transmission system (WPTS) with a wireless power receiver client (WPRC) in a localized system. A current WPTS-WPRC pairing and at least one alternate WPTS-WPRC pairing are assessed and the WPTS-WPRC pairing is updated based on associated pairing quality metrics. In this way, a system of many WPTSs and WPRCs will approach an Epsilon equilibrium such that no WPRC would be significantly better served by being paired with a different WPTS.
