Abstract
In some example embodiments, there may be provided an apparatus. The apparatus may include a surface including at least one electro-magnetic reflective element programmed to provide a plurality of reflected signals, such that the plurality of reflected signals constructively adds at a location of a receiver of the plurality of reflected signals. Related systems, methods, and articles of manufacture are also described.
Claims15
An apparatus comprising:
- a surface including at least one electro-magnetic reflective element programmed to provide a plurality of reflected signals, such that the plurality of reflected signals constructively add at a location of a receiver of the plurality of reflected signals, wherein the electro-magnetic reflective element is coupled to at least one at least one programmable phase shifter;
- and
- a controller that configures the at least one programmable phase shifter, such that the plurality of reflected signals add constructively at the location of the receiver of the plurality of reflected signals, and wherein the controller programs, during a phase offset determination phase, the at least one phase programmable shifter in a first predetermined phase configuration, a second predetermined phase configuration, and a third predetermined phase configuration to enable a first packet, a second packet, and a third packet to be reflected toward the location of the receiver.
A method comprising:
- receiving configuration information for an apparatus including a surface, the surface further including at least one electro-magnetic reflective element, wherein the electro-magnetic reflective element is coupled to at least one at least one programmable phase shifter;
- and
- programing, based on the received configuration information, a configuration of the surface including the at least one electro-magnetic reflective element, such that a plurality of reflected signals constructively add at a location of a receiver of the plurality of reflected signals, wherein the programming further includes programming, during a phase offset determination phase, the at least one phase programmable shifter in a first predetermined phase configuration, a second predetermined phase configuration, and a third predetermined phase configuration to enable a first packet, a second packet, and a third packet to be reflected toward the location of the receiver.
