Abstract

A simplified field testing tool integrates signal-strength and error-rate testing for a variety of networking technologies prevalent for home networking, including but not limited to Multimedia over Coax (or applicable coax standard), HomePNA 2, VDSL, 100BaseT Ethernet, 802.11 Wi-Fi, and analog/coaxial RF signals.

Claims

1. A signal detector to measure telecommunications signals, the signal detector comprising:

a housing holding electronics to measure a signal associated with a telecommunications protocol and to determine whether the measured signal is within a predetermined range associated with the telecommunications protocol, wherein the signal comprises one of a multimedia over coax (MoCa) signal, an analog radio frequency (RF) signal, a home phoneline networking alliance (HPNA) signal, a digital subscriber line (xDSL) signal, an Ethernet signal, and a Wi-Fi signal;

a power source to power the electronics;

at least one port on the housing to connect to the signal detector a media coupled to a signal source, wherein the media comprise coaxial cable media, Ethernet cable media, and telephone cable media;

a source selector connected to the signal detector to select a signal for measurement from the at least one port; and

an indicator mounted on the housing to indicate whether the measured signal of the signal source is within the predetermined range associated with the telecommunications protocol.

2. The signal detector of claim 1, further comprising an integral Wi-Fi antenna to wirelessly measure the Wi-Fi signal.

3. The detector of claim 1, wherein the indicator is operable to indicate that the measured signal of the signal source is within the predetermined range associated with the telecommunications protocol by measuring a signal strength of the selected signal and comparing the measured signal strength to a predetermined range associated with the telecommunications protocol.

4. The signal detector of claim 1, wherein the detector measures a bit error rate (BER) to noise (BER/noise) ratio of the selected signal.

5. The signal detector of claim 1, further comprising a mode selector to select a detection mode from among a signal strength detection mode and a BER/noise ratio detection mode.

6. The signal detector of claim 1, wherein the indicator comprises a numeric display to display a numeric value corresponding to a strength of the measured signal.

7. The signal detector of claim 1, wherein the indicator comprises a light emitting diode (LED) that illuminates when a detected signal is within the predetermined range associated with the telecommunications protocol.

8. The signal detector of claim 1, wherein the indicator comprises both a numeric display to display a numeric value corresponding to the measured signal strength of a detected signal and an LED that indicates when the measured signal strength is within the predetermined range associated with the telecommunications protocol.

9. The signal detector of claim 1, wherein the xDSL signal comprises a very high bitrate DSL (VDSL) signal.

10. The signal detector of claim 1, wherein the detector measures signals associated with a consumer premises equipment (CPE) device.

11. A signal detector to selectively measure a plurality of telecommunications signals and to selectively measure the strength and the BER/noise ratio of a selected signal, the signal detector comprising:

a housing holding electronics to measure a signal associated with a telecommunications protocol and to determine whether the measured signal is within a predetermined range associated with the telecommunications protocol, wherein the signal comprises one of a multimedia over coax (MoCa) signal, an analog radio frequency (RF) signal, a home phoneline networking alliance (HPNA) signal, a digital subscriber line xDSL signal, an Ethernet signal, and a WiFi signal;

a power source to power the electronics;

a plurality of ports on the housing to connect to the signal detector a media coupled to a signal source, wherein the signal source further comprises coax, Ethernet, telephone and Wi-Fi;

a source selector connected to the detector to select a signal for measurement from the signal source;

a mode selector connected to the detector to select one of a signal strength detection mode and a bit error rate to noise ratio (BER/noise ratio) detection mode; and

an indicator mounted on the housing to indicate whether the measured signal of the selected signal from the signal source is within the predetermined range associated with the telecommunications protocol.

12. The signal detector of claim 11, wherein the indicator comprises a numeric display to display a numeric value corresponding to a strength of the measured signal.

13. The signal detector of claim 11, wherein the indicator comprises a light emitting diode (LED) that illuminates when a measured signal is within the predetermined range associated with the telecommunications protocol.

14. The signal detector of claim 11, wherein the indicator comprises both a numeric display to display a numeric value corresponding to a strength of a detected signal and an LED that indicates when the measured signal is within the predetermined range associated with the telecommunications protocol.

15. The signal detector of claim 11, wherein the xDSL signal comprises a very high bitrate DSL (VDSL) signal.

16. The signal detector of claim 11, wherein the detector measures signals associated with a consumer premises equipment (CPE) device.

17. A method of measuring a telecommunications signal, the method comprising:

receiving a signal associated with a telecommunications protocol, wherein the signal comprises one of a multimedia over coax (MoCa) signal, an analog radio frequency (RF) signal, a home phoneline networking alliance (HPNA) signal, a digital subscriber line (xDSL) signal, an Ethernet signal, and a WiFi signal;

measuring a strength of the signal;

determining whether the measured signal strength is within a predetermined range associated with the telecommunications protocol; and

indicating when the measured signal strength is within the predetermined range associated with the telecommunications protocol.

18. The method of claim 17, further comprising indicating when the measured signal strength is not within the predetermined range associated with the telecommunications protocol.

19. The method of claim 17, wherein a light emitting diode is used to indicate that the measured signal strength is not within the predetermined range.

20. The method of claim 17, wherein the signal is received from a customer premises equipment (CPE) device.
