Abstract

Disclosed aspects relate to wireless power distribution management in an open environment. A key-pair identifier is established in a master server. The key-pair identifier can indicate both a first wireless power target device and a first wireless power source distribution center. The master server detects an indication of a wireless power coupling between the first wireless power target device and a second wireless power source distribution center. A usage assessment is determined for the wireless power coupling by the master server using the key-pair identifier. The usage assessment can relate to the first wireless power source distribution center. The master server may provide or output the usage assessment for the wireless power coupling.
