Claim 11:
12. A wireless power transfer system comprising:
one or more wireless power receivers; and
a wireless power transmission system configured for communications with one or more wireless power receiver systems operating within a communications frequency band, the wireless power transmission system including
a plurality of wireless power transmitters, each including a power transmitting coil for an antenna, each of the plurality of wireless power transmitters configured to transmit electrical power, within a charge envelope, to one of the one or more wireless power receiver systems;
at least one wireless power transfer circuit electrically connectable to one or more of the plurality of wireless power transmitters, the at least one wireless power transfer circuit including, at least, driving circuitry; and
at least one transmitter controller, the at least one transmitter controller configured for controlling one or more of the plurality of wireless power transmitters and configured for communicating with a receiver controller of one of the one or more wireless power receivers, the at least one transmitter controller configured to
determine presence of at least one of the one or more wireless power receiver systems,
one or more of encode or decode a communications signal communicated over a magnetic field, produced by coupling of the one of the plurality of wireless power transmitters and one of the one or more wireless power receiver systems,
determine presence of one or more of unwanted noise associated with another of the one or more wireless power receiver systems, unwanted data associated with another of the one or more wireless power receiver systems, or combinations thereof within a proximity communications frequency band, the proximity communications frequency band substantially similar to the communications frequency band, and
filter the one or more of unwanted noise associated with another of the one or more wireless power receiver systems, unwanted data associated with another of the one or more wireless power receiver systems, or combinations thereof to determine a filtered communications signal.
