Abstract
A network access device placed between one or more distribution devices and multiple premises may remotely or wirelessly monitor and/or analyze signal characteristics at the network access device and or of equipment at the multiple premises. The network access device may adjust switchably-filtered signal paths between the distribution device(s) and the multiple premises to remove or mitigate signal interference.
Claims30
A method comprising:
- receiving, by a network access device and via a portion of an upstream bandwidth of a communication medium, one or more upstream signals;
- determining, based on reflection of at least a portion of the one or more upstream signals, one or more modifications to one or more signal paths, of a plurality of signal paths of the network access device, associated with one or more devices affected by the reflection;
- and
- causing, by the network access device, the determined one or more modifications to the one or more signal paths.
1 more element
A method comprising:
- sending, by a computing device to a network access device, a request for one or more signal characteristics associated with upstream signals received, via a communication medium, by the network access device;
- receiving, from the network access device, a first message indicating the one or more signal characteristics;
- and
- sending, based on the one or more signal characteristics, a second message configured to cause the network access device to perform one or more modifications to one or more signal paths of a plurality of signal paths of the network access device.
