Abstract

Systems, methods, and apparatuses for remote evaluation of content delivery service are described. A remote computing device may determine the existence and performance characteristics of devices and equipment at a premises by monitoring and analyzing data from a network associated with the premises to determine the presence or absence of equipment, compatibility issues, and performance quality.

First claim

We claim:

1. A method comprising:
receiving, by a computing device and from a first device associated with a premises, probe data indicative of signal loss between the first device and a second device;
determining, based on the probe data for a plurality of frequencies, a frequency response;
determining, based on comparing a peak of the frequency response with one or more profiles, that the first device or the second device comprises a Point of Entry (POE) filter;
determining, based on a signal delay associated with the peak, a distance between the first device and the second device; and
sending, based on determining that the first device or the second device comprises the POE filter and based on determining that the distance between the first device and the second device satisfies a threshold, an alert signal.

2. The method of claim 1 , wherein the one or more profiles comprises POE filter profiles.

3. The method of claim 1 , further comprising:
determining a threshold region of the frequency response; and
determining a highest magnitude peak of the frequency response outside of the threshold region.

4. The method of claim 1 , further comprising:
determining, based on a connection type between the first device and the second device, a propagation delay; and
adjusting, based on the propagation delay, the signal delay.

5. The method of claim 1 , further comprising:
normalizing the probe data by zero-padding sample points of the probe data; and
determining, based on the probe data and based on the normalized probe data, a frequency scale;
wherein determining the signal delay is further based on the frequency scale.

6. The method of claim 1 , wherein determining that the distance between the first device and the second device satisfies the threshold comprises determining that the distance between the first device and the second device is greater than ten feet.

7. A method comprising:
receiving, by a computing device remote and from a premises from a first device at the premises, probe data indicative of signal loss between the first device and a second device at the premises;
determining, based on the probe data for a plurality of frequencies, a frequency response;
comparing a peak of the frequency response with one or more Point of Entry (POE) filter profiles;
determining, based on the comparing, whether the first device or the second device comprises a POE filter; and
generating, based on determining that the first device or the second device comprises the POE filter, a confirmation signal.

8. The method of claim 7 , further comprising:
sending, by the computing device, via a simple network management protocol, and to the first device, instructions to measure characteristics of a network comprising the first device and the second device.

9. The method of claim 7 , further comprising:
determining a threshold region of the frequency response; and
wherein comparing the peak of the frequency response with the one or more POE filter profiles further comprises selecting a highest magnitude peak of the frequency response outside of the threshold region as the peak of the frequency response.

10. The method of claim 7 , further comprising:
determining whether a continuous wave path loss between the first device and the second device is between −40 decibel millivolts (dBmV) and 40 dBmV;
wherein determining whether the first device or the second device comprises the POE filter is further based on determining that the continuous wave path loss between the first device and the second device is greater than 40 dBmV or lower than −40 dBmV.

11. The method of claim 7 , further comprising:
normalizing the probe data by zero-padding sample points of the probe data;
determining, based on the probe data and based on the normalized probe data, a frequency scale; and
determining, based on the frequency scale and based on the peak of the frequency response, a signal delay.

12. The method of claim 7 , further comprising:
determining, based on the peak, a signal delay;
adjusting, based on a propagation delay associated with a network comprising the first device and the second device, the signal delay; and
determining, based on the adjusted signal delay, a distance between the first device and the second device.

13. The method of claim 12 , further comprising:
sending, based on determining that the distance between the first device and the second device is within ten feet, a confirmation signal.

14. A method comprising:
receiving, by a computing device and from a first device associated with a premises, probe data indicative of signal loss between the first device and a second device;
determining, based on the probe data, a frequency response;
determining a region of the frequency response corresponding to signal delays of less than a threshold amount of time;
determining a peak of the frequency response outside of the determined region;
determining, based on the peak and based on a propagation delay associated with a network comprising the first device and the second device, a signal delay;
determining, based on the signal delay, a distance between the first device and the second device; and
sending, based on determining that the distance satisfies a threshold distance, an alert signal.

15. The method of claim 14 , further comprising:
determining, based on comparing the peak with one or more Point of Entry (POE) filter profiles, that the first device or the second device comprises a POE filter.

16. The method of claim 14 , wherein the computing device is remote from the premises.

17. The method of claim 14 , further comprising determining that the first device or the second device comprises a root splitter.

18. The method of claim 14 , further comprising:
normalizing the probe data by zero-padding sample points of the probe data; and
determining, based on the probe data and based on the normalized probe data, a frequency scale;
wherein determining the signal delay is further based on the frequency scale.

19. The method of claim 14 , wherein determining that the distance satisfies the threshold distance comprises determining that the distance between the first device and the second device is greater than ten feet.

20. The method of claim 14 , wherein the threshold amount of time comprises twenty nanoseconds.
