SYSTEM AND METHOD FOR COMMUNICATING BETWEEN NEAR FIELD COMMUNICATION DEVICES WITHIN A TARGET REGION USING NEAR FIELD COMMUNICATION

摘要

Systems and methods for communication between near field communication devices within a target communication region using near field magnetic induction is disclosed. One method comprises generating a near field detectable signal at an active node having a power level sufficient to enable communication with a plurality of near field communication nodes located within the target communication region. Information is modulated onto the near field detectable signal using at least one of the near field communication nodes. The modulated information is detected at the active node. The information is then relayed on the near field detectable signal from the active node to at least one of the plurality of near field communication nodes within the target communication region.

1. A system for communication between near field communication devices within a target communication region using near field magnetic induction, comprising:
an active node with a near field magnetic induction transducer configured to generate a near field detectable signal within a target communication region; and a plurality of near field communication nodes located within the target communication region that are configured to sense the near field detectable signal and modulate information onto the near field detectable signal, wherein the active node is configured to detect the information modulated onto the near field detectable signal and relay the information to at least one of the plurality of near field communication nodes using the near field detectable signal to enable the plurality of near field communication nodes to send information to selected near field communication nodes within the target region through the active node.
