Abstract
Systems and methods for modulating a telepowering signal in a downlink communication. Embodiments of the present invention provide a fingerprint module to generate a fingerprint signal that can be modulated with a telepowering signal for communication by a transmission module in a downlink communication. The fingerprint signal is reflected by a wayside equipment module and received by the transmission module to enable an additional communication other than the downlink communication and an uplink communication.
