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.
Claims21
A method, comprising:
- establishing a downlink communication between a downlink transmitter and a downlink receiver;
- the downlink transmitter transmitting a telepowering signal in the downlink communication;
- the downlink transmitter transmitting a fingerprint signal modulated with the telepowering signal in the downlink communication;
- and
- the downlink receiver reflecting the fingerprint signal to the downlink transmitter;
- wherein the step of reflecting the fingerprint signal comprises changing a path of the fingerprint signal when the fingerprint signal encounters a surface of the downlink receiver.
3 more elements
A system, comprising:
- a balise transmission module that includes a downlink wireless transmitter and an uplink wireless receiver;
- and
- a balise that includes an uplink wireless transmitter and a downlink wireless receiver;
- wherein the balise and the balise transmission module are configured to establish a downlink channel to communicate a first signal and an uplink channel to communicate a second signal;
- wherein the balise transmission module is configured to communicate a third signal modulated with the first signal to the balise with the downlink channel the third signal comprising a fingerprint signal;
- wherein the balise reflects the fingerprint signal by changing a path of the fingerprint signal when the fingerprint signal encounters a surface of the balise;
- and
- the balise transmission module includes a fingerprint receiver that detects a fingerprint signal from the third signal reflected from the balise.
5 more elements
A system, comprising:
- a transmission module that includes at least one first transmitter and at least one first receiver;
- wherein the transmission module is configured for communication with a wayside equipment module that includes at least one second transmitter and at least one second receiver, and wherein the communication includes:
- an uplink that includes a first wireless transmission from the wayside equipment module to the transmission module;
- a downlink that includes a second wireless transmission from the transmission module to the wayside equipment module;
- and
- the downlink includes a fingerprint signal that is communicated with a telepowering signal from the transmission module to the wayside equipment module and reflected from the wayside equipment module to the transmission module;
- wherein the wayside equipment module reflects the fingerprint signal by changing a path of the fingerprint signal when the fingerprint signal encounters a surface of the wayside equipment module.
4 more elements
A system, comprising:
- a wayside equipment module that includes at least one second transmitter and at least one second receiver;
- wherein the wayside equipment module is configured for communication with a transmission module that includes at least one first transmitter and at least one first receiver;
- and
- wherein the communication includes:
- an uplink that includes a first wireless transmission from the wayside equipment module to the transmission module;
- a downlink that includes a second wireless transmission from the transmission module to the wayside equipment module;
- and
- the downlink includes a fingerprint signal that is communicated with a telepowering signal from the transmission module to the wayside equipment module and reflected from the wayside equipment module to the transmission module;
- wherein the wayside equipment module reflects the fingerprint signal by changing a path of the fingerprint signal when the fingerprint signal encounters a surface of the wayside equipment module.
