Abstract

Techniques for testing a wireless communications device are disclosed. In one particular exemplary embodiment, the techniques may be realized as a system and method for testing a wireless communications device. The method may comprise generating an audio test signal. The audio test signal may be transmitted to a wireless communication device through a wireless base station simulator via a VoIP application. The method may also comprise receiving an output signal, where the output signal may be generated by the wireless communication device and transmitted to a telecoil probe. The method may further comprise processing the output signal by comparing the output signal with the audio test signal.

Claims

1. A system for testing a wireless communication device, comprising:

an audio test system;

a wireless base station simulator;

a wireless communication device;

a source VoIP application;

a client VoIP application; and

a telecoil probe;

wherein the wireless communication device is configured to;

receive, at the wireless communication device, an audio test signal from the wireless base station simulator, wherein the audio test signal is transmitted via the source VoIP application;

generate an output signal in response to the audio test signal; and

transmit an output signal to the telecoil probe, wherein the telecoil probe is communicatively coupled to the audio test system for testing the wireless communication device.

2. The system of claim 1, wherein the client VoIP application is in the wireless communications device.

3. The system of claim 1, wherein the wireless base station simulator is an LTE base station simulator.

4. The system of claim 1, wherein the output signal is amplified after being received by the telecoil probe.

5. The system of claim 1, wherein the audio test signal is generated by the audio test system.

6. The system of claim 1, wherein the audio test system processes the output signal by comparing the output signal with the audio test signal.

7. A method for testing a wireless communications device, comprising:

receiving, at a wireless communication device, an audio test signal from a wireless base station simulator, wherein the audio test signal is transmitted from a source Voice over Internet Protocol (VoIP) application to a client VoIP application;

generating an output signal in response to the audio test signal; and

transmitting the output signal to a telecoil probe, wherein the telecoil probe is communicatively coupled with an audio test system configured to test the wireless communication device.

8. The method of claim 7, wherein the client VoIP application is in the wireless communications device.

9. The method of claim 7, wherein the wireless base station simulator is an LTE base station simulator.

10. The method of claim 7, wherein the output signal is amplified after being received by the telecoil probe.

11. The method of claim 7, wherein the audio test signal is generated by the audio test system.

12. The method of claim 11, wherein the audio test system is configured to test the wireless communication device by at least comparing the output signal with the audio test signal.

13. A non-transitory computer-readable storage medium storing a computer program of instructions configured to be readable by at least one computer processor for instructing the at least one computer processor to execute a computer process for performing the method of claim 7.

14. A method for testing a wireless communications device, comprising:

generating an audio test signal, wherein the audio test signal is transmitted to a wireless communication device through a wireless base station simulator from a source VoIP application to a client a VoIP application;

receiving an output signal, wherein the output signal is generated by the wireless communication device and transmitted to a telecoil probe; and

processing the output signal by comparing the output signal with the audio test signal.

15. The method of claim 14, wherein the client VoIP application is in the wireless communications device.

16. The method of claim 14, wherein the wireless base station simulator comprises an LTE base station simulator.

17. The method of claim 14, wherein the output signal is amplified after being received by the telecoil probe.

18. The method of claim 14, wherein the processing the output signal further comprises breaking the output signal a spectrum of ⅓

octave bands.

19. The method of claim 14, wherein the generating the audio test signal further comprises generating a 1 kHz tone.

20. A non-transitory computer-readable storage medium storing a computer program of instructions configured to be readable by at least one computer processor for instructing the at least one computer processor to execute a computer process for performing the method of claim 14.
