Claim 0:
1. A system for noise profile generation comprising:
a customer gateway communicatively coupled to one or more end devices over a communication medium;
at least one noise information node, each of the at least one noise information node communicatively coupled to the customer gateway, wherein each of the at least one noise information node is programmed to extract an extracted noise information present on a communication path from the customer gateway to at least one of the one or more end devices, wherein each of the at least one noise information node has a first unique identifier and is further programmed to identify a new end device connected to the communication path;
a noise profile database storing one or more noise profiles, wherein each of the one or more noise profiles is respectively associated with at least one noise source; and
a noise profile generator comprising:
at least one processor;
non-transitory computer readable media having encoded thereon computer software comprising a set of instructions executable by the at least one processor to:
based on an identification, by the at least one noise information node, that the new end device has been connected to the communication path, identify, based on a corresponding first unique identifier associated with the at least one noise information node and at the noise profile database, existing noise information associated with the communication path, associate a second unique identifier of the new end device with the extracted noise information, subtract the existing noise information from the extracted noise information resulting in an added noise information, and generate, based on the added noise information, an isolated noise profile associated with the new end device,
wherein the communication medium comprises a transmission spectrum, wherein the transmission spectrum includes a plurality of sub-carrier channels, each sub-carrier channel spanning a respective frequency range within the transmission spectrum, wherein each of the at least one noise information node is a wireless transceiver programmed to:
receive, from the customer gateway, a signal on each of the plurality of sub-carrier channels, wherein the extracted noise information is extracted respectively from each of the plurality of subcarrier channels; and
determine, based on the extracted noise information, a signal-to-noise ratio respectively for each of the subcarrier channels.
