Backscatter device placement and placement calibration

A system comprising:

• a memory storage;
• and
• a processing unit coupled to the memory storage, wherein the processing unit is operative to:
• cause a plurality of ambient energy sources of a Three-Dimensional (3D) space to transmit charging frames for Backscatter Devices (BKDs), each of the charging frames comprising a payload having a Media Access Control (MAC) address of transmitting ambient energy source;
• receive from one or more survey devices placed at one or more positions along a sub-space of the 3D space an amount of ambient energy received from the charging frames of the plurality of ambient energy sources and received from each contributing source from the MAC address included in the charging frames;
• and
• predict the amount of ambient energy available from each contributing source at each of the one or more positions along the sub-space per predetermined time period based on the amount of ambient energy received from the plurality of ambient energy sources.

A non-transitory computer-readable medium that stores a set of instructions which when executed perform a method comprising:

• causing a plurality of ambient energy sources of a Three-Dimensional (3D) space to transmit charging frames for Backscatter Devices (BKDs), each of the charging frames comprising a payload having a Media Access Control (MAC) address of transmitting ambient energy source;
• receiving from one or more survey devices placed at one or more positions along a sub-space of the 3D space an amount of ambient energy received from the charging frames of the plurality of ambient energy sources and received from each contributing source from the MAC address included in the charging frames;
• and
• predicting the amount of ambient energy available from each contributing source at each of the one or more positions along the sub-space per predetermined time period based on the amount of ambient energy received from the plurality of ambient energy sources.
