Abstract

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for transmitting, by a first device, a transmission signal that includes a carrier signal modulated with a TM signal. Receiving a response signal from a second device in response to the transmission signal. Determining, whether the response signal includes the TM signal.

Claims

1. A method for identifying transpositional modulation (TM) capable Internet of Things (IoT) devices, the method comprising:

transmitting, by a computer networking device having a TM capable radio transmitter, a transmission signal that includes a carrier signal modulated with a TM signal;

receiving a response signal from an IoT device in response to the transmission signal; and

determining, by the computer networking device, whether the response signal includes the TM signal.

2. The method of claim 1, further comprising determining that the IoT device is a TM capable device based on determining that the response signal includes the TM signal.

3. The method of claim 1, wherein determining whether the response signal includes the TM signal comprises mixing the response signal with a second harmonic of a carrier signal of the response signal to produce a mixed signal.

4. The method of claim 1, wherein the transmission signal includes the carrier signal modulated with the TM signal and a non-TM modulation signal.

5. The method of claim 1, wherein the response signal includes a non-TM modulation signal.

6. The method of claim 5, wherein determining whether the response signal includes the TM signal comprises removing the non-TM modulation signal from the response signal.

7. The method of claim 1, wherein the transmission signal incudes the carrier signal modulated with a first TM signal, and wherein determining whether the response includes the TM signal comprises determining whether the response signal includes a second, different TM signal.

8. The method of claim 7, wherein the second TM signal includes information about the IoT device.

9. The method of claim 8, wherein the information includes information identifying the IoT device.

10. The method of claim 8, wherein the information includes information identifying characteristics of the IoT device.

11. The method of claim 7, wherein the second TM signal includes information about network channel characteristics.

12. The method of claim 7, wherein the second TM signal includes information about other TM capable devices in communication with the IoT device.

13. A method for providing device identification data from Internet of Things (IoT) devices, the method comprising:

receiving, by an IoT device, a transmission signal from a computing device, the transmission signal including a carrier signal modulated with a first transpositional modulation (TM) signal;

identifying the first TM signal within the transmission signal; and

sending, by the IoT device to the computing device, a response signal that includes data encoded within a second TM signal.

14. The method of claim 13, wherein the transmission signal includes the carrier signal modulated with the TM signal and a non-TM modulation signal.

15. The method of claim 13, wherein the response signal includes a non-TM modulation signal.

16. The method of claim 14, wherein identifying the first TM signal within the transmission signal comprises removing the non-TM modulation signal from the transmission signal.

17. The method of claim 13, wherein the data encoded within the second TM signal includes information about the IoT device.

18. The method of claim 17, wherein the information includes information identifying characteristics of the IoT device.

19. The method of claim 13, wherein the second TM signal includes information about network channel characteristics.

20. The method of claim 13, wherein the second TM signal includes information about other TM capable devices in communication with the IoT device.
