摘要： An antenna alignment apparatus may include magnetic field sensors as an alternative to or in addition to GNSS sensors. The magnetic field sensors may measure the earth's magnetic fields at corresponding locations, and a processor may use the measurements to calculate at least one of a roll, tilt, or azimuth of an antenna. A declination based on GNSS based alignment and magnetic field sensor alignment may be stored for an adjustment of magnetic field sensor based azimuth calculations. For an optical alignment, the antenna alignment apparatus may, additionally or alternately, include a reference object (e.g., a printed mark or a physical stud) located within a field of view of a camera. A location of the reference object may indicate the alignment of the antenna vis-à-vis the structures within the field of view.

摘要： An intelligent monitoring and testing system for a cable network determines measurements for a cable plant (CP), including cable modems (CMs) and common network elements, Metrics determined from the measurements are analyzed to detect a service issue and a service sub-issue. Machine learning is applied to the metrics and other related data to determine an optimized workflow for diagnosing, locating, and remediating the service issue and service sub-issue.

摘要： An example smart antenna mount may couple an antenna alignment device with an antenna. The smart antenna mount may include sensors such as strain gauges and accelerometers, and an electronic circuitry to communicate the measurements from the sensors. The measurements are received by the antenna alignment device, which may perform further operations to determine whether the coupling is within desired bounds. If within desired bounds, the antenna alignment device may generate an indication of a normal coupling, e.g., by activating a first colored (e.g., green) LED. If the coupling is outside the desired bounds, the antenna alignment device may indicate an alarm condition, e.g., activating a second colored (e.g., red) LED or generating an audible signal.

摘要： In some examples, signal leakage monitoring based quality control may include measuring, by a signal leakage level detector, for a signal leak at a specified location, a signal leakage level. The signal leak may include a status of being open. A geo-location value and a time value associated with the measurement of the signal leakage level may be assigned to the signal leakage level. A signal leakage closure quality analyzer may transmit the signal leakage level, the geo-location value, and the time value to a signal leakage analyzer. Further, the signal leakage closure quality analyzer may receive, from the signal leakage analyzer and based on an analysis of the signal leakage level, the geo-location value, and the time value by the signal leakage analyzer, an indication that the status of the signal leak is changed from being open to closed, or the status of the signal leak remains open.
