1. A method for a controllable device, comprising steps of:

  • receiving a controlled quasi-transient signal superimposed on a venue-intrinsic signal propagated in the air or through distance in a venue where a controllable device is, wherein;

    (a) the venue-intrinsic signal is emitted from infrastructure intrinsic to the venue and is otherwise unintended for wireless communication via the infrastructure with the controllable device, wherein the venue-intrinsic signal includes at least one of an electric signal emitted by a utility line or by an electric wire,(b) the controlled quasi-transient signal comprises a quasi-transient signal coded with venue-relevant information, and(c) the controlled quasi-transient signal is a signal generated for application to the venue-intrinsic signal for emission from the infrastructure intrinsic to the venue as one or more fast rise-time bursts with spectral and power density characteristics similar to the uncontrolled transients of the venue-intrinsic signal;

    extracting the venue-relevant information, associated with the venue where the controllable device is, from the controlled quasi-transient signal; and

    controlling at least one function of the controllable device in accordance with a control signal generated based on the venue-relevant information, wherein the venue-relevant information corresponds to a geographic region related to the venue.
