Abstract
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.
