Abstract

A tester system described herein enables a user (e.g., a field technician) to efficiently and conveniently upgrade, evaluate and troubleshoot customer premises networks and equipment. The tester system includes a dedicated tester device that is wirelessly coupled to a handheld device. In response to user input, the handheld device remotely controls the dedicated tester device to execute a testing routine to evaluate one or more customer premises wired and/or wireless networks.

Claims

1. A tester device to evaluate a wired network, the tester device including:

a first wired connector to couple the tester device to the wired network;

a second wired connector to couple the tester device to the wired network;

wherein the tester device is not incorporated into a service provider installed interface or customer-premises equipment (CPE);

a wireless transceiver or a bridge to a wireless transceiver to wirelessly couple the tester device to a handheld device; and

a signal processing module coupled to the first and second wired connectors and the wireless transceiver, and including logic to;

emulate, as the CPE, a set-top box to receive a first signal on the first wired connector;

emulate, as the CPE, a modem to send or receive a second signal on the second wired connector;

receive command data from the handheld device to execute a testing routine on the first signal and the second signal; and

transmit information regarding the first signal or the second signal and the testing routine for display on the handheld device.

2. The tester device of claim 1, wherein the tester device does not include an output for displaying the information to a user.

3. The tester device of claim 1, wherein the tester device does not include a user input device for receiving direct user interaction corresponding to a command to execute the testing routine.

4. The tester device of claim 1, wherein:

the first signal is a voice over IP signal; and

the set-top box is emulated to receive the voice over IP signal.

5. The tester device of claim 4, wherein the voice over IP signal is analyzed to produce reports concerning video quality of the analyzed voice over IP signal.

6. The tester device of claim 4, wherein:

the voice over IP signal is converted into a format suitable for display on the handheld device; and

the converted voice over IP signal is transmitted to the handheld device.

7. The tester device of claim 1, wherein:

the first signal is a video signal; and

the set-top box is emulated to receive the video signal.

8. The tester device of claim 7, wherein the signal processing module includes logic to analyze the received video signal to produce reports concerning video quality of the analyzed video signal.

9. The tester device of claim 7, wherein the signal processing module includes logic to convert the received video signal into a format suitable for display on the handheld device, and to transmit the converted video signal to the handheld device.

10. A tester device to evaluate a wired and a wireless network, the tester device including:

a wired connector to couple the tester device to the wired network;

a wireless connector to couple the tester device to the wireless network;

wherein the tester device is not incorporated into a service provider installed interface or customer-premises equipment (CPE);

a wireless transceiver or a bridge to a wireless transceiver to wirelessly couple the tester device to a handheld device; and

a signal processing module coupled to the wired connector and the wireless connector, and including logic to;

receive a first signal on the wired connector;

execute a first testing routine on the received first signal;

receive a second signal on the wireless connector;

execute a second testing routine on the received second signal; and

transmit information regarding the received first signal and the first testing routine or information regarding the received second signal and the second testing routine for display on the handheld device.

11. The tester device of claim 10, wherein the information concerns a power level of the received second signal.

12. The tester device of claim 10, wherein the information concerns a frequency spectrum of the received second signal.

13. The tester device of claim 10, wherein the information indicates short circuits and open circuits within the wired network.

14. A method of evaluating a wired network using a tester device not incorporated into a service provider installed interface or customer-premises equipment (CPE), the method including:

connecting a first wired connector and a second wired connector of the tester device to the wired network;

wirelessly coupling the tester device to a handheld device;

emulating a first signal on the first wired connector by emulating, as the CPE, a set-top box;

sending or receiving a second signal on the second wired connector by emulating, as the CPE, a modem;

receiving command data from the handheld device to execute a testing routine on the first signal and the second signal; and

transmitting information regarding the first signal or the second signal and the testing routine for display on the handheld device.

15. The method of claim 14, wherein:

one of the first signal and the second signal is a video signal; and

the tester device emulates a set-top box to receive the video signal.

16. The method of claim 15, wherein the tester device analyzes the received video signal to produce reports concerning video quality of the analyzed video signal.

17. The method of claim 15, including the tester device converting the received video signal into a format suitable for display on the handheld device, and transmitting the converted video signal to the handheld device.

18. The method of claim 15, further including:

wirelessly coupling a wireless connector of the tester device to a wireless network;

the tester device receiving a second signal on the wireless connector;

the tester device receiving command data from the handheld device to execute a second testing routine on the received second signal;

the tester device analyzing the received second signal to produce reports concerning one or more performance metrics of the received second signal; and

the tester device transmitting the reports for display on the handheld device.

19. The method of claim 15, further comprising producing reports indicating short circuits and open circuits within the wired network.

20. A method of evaluating a wired network using a tester device not incorporated into a service provider installed interface or customer-premises equipment (CPE), the method including:

connecting a wired connector of the tester device to the wired network;

wirelessly coupling the tester device to a handheld device;
