1. A method of selectively scheduling wireless power delivery in a wireless power delivery environment, the method comprising:
- broadcasting, by a wireless power transmission system, a network sharing message in the wireless power delivery environment;
responsive to broadcasting the network sharing message, receiving, by the wireless power transmission system, a wireless power consumption request initiated by a first wireless power receiver in the wireless power delivery environment, wherein the wireless power consumption request uniquely identifies the first wireless power receiver;
determining that the first wireless power receiver belongs to a set of wireless power receivers synchronized with the wireless power transmission system;
generating a wireless power delivery schedule for delivering directed wireless power to multiple wireless power receivers in the wireless power delivery environment, wherein the wireless power delivery schedule is time-sliced among the multiple wireless power receivers including one or more time slots assigned to the first wireless power receiver; and
delivering directed wireless power to the first wireless power receiver during the one or more time slots.

Abstract
Techniques are described herein for determining which power receiver clients are within a set network and limiting power transmission to these select clients. Ignoring some power requests frees up the wireless power transmission system to preferentially supply power to wireless power receiver clients that are determined to be of higher importance. This may be particularly beneficial within a home or business setting where the wireless power transmission system coverage region extends into locations where unknown devices are located.

15. A wireless power transmission system, comprising:
-
an adaptively-phased antenna array having multiple radio frequency (RF) transceivers; control circuitry coupled with the adaptively-phased antenna array and configured to; direct one or more transceivers to broadcast a network sharing message in a wireless power delivery environment; process a wireless power consumption request initiated by a first wireless power receiver in the wireless power delivery environment, wherein the wireless power consumption request uniquely identifies the first wireless power receiver; determine that the first wireless power receiver belongs to a set of wireless power receivers synchronized with the wireless power transmission system; generate a wireless power delivery schedule for delivering directed wireless power to multiple wireless power receivers in the wireless power delivery environment wherein the wireless power delivery schedule is time-sliced among the multiple wireless power receivers including one or more time slots assigned to the first wireless power receiver; and direct one or more transceivers to deliver directed wireless power to the first wireless power receiver during the one or more time slots. - View Dependent Claims (16, 17, 18, 19)

20. A non-transitory computer-readable storage medium having program instructions stored thereon which, when executed by one or more processors of a wireless power transmission system, cause the wireless power transmission system to:
-
broadcast a network sharing message in a wireless power delivery environment; process a wireless power consumption request initiated by a first wireless power receiver in the wireless power delivery environment, wherein the wireless power consumption request uniquely identifies the first wireless power receiver; determine that the first wireless power receiver belongs to a set of wireless power receivers synchronized with the wireless power transmission system; and generate a wireless power delivery schedule for delivering directed wireless power to multiple wireless power receivers in the wireless power delivery environment, wherein the wireless power delivery schedule is time-sliced among the multiple wireless power receivers including one or more time slots assigned to the first wireless power receiver; deliver directed wireless power to the first wireless power receiver during the one or more time slots.
