Abstract :
Use of heating, ventilation, and air conditioning (HVAC) ducts for indoor communications is a topic of recent interest. Real HVAC networks are complex systems, which contain multiple bends, tapers, etc. In this paper, we present a propagation model for such cascaded networks. based on the transfer matrix method. As an example, we theoretically analyze and experimentally characterize a system composed of straight sections, bend and taper. Measured data are in agreement with our theoretical predictions.
