One or more upstream radio frequency (RF) signals have a carrier frequency of between approximately 5 MHz and 19.6 MHz and are modulated using quadrature amplitude modulation (QAM) with voice and/or data information constituting at least some of the upstream information. An example RF signal defines a channel having an average channel power, and a highest value for an average noise power between 5 MHz and 19.6 MHz in the upstream path bandwidth of a given neighborhood node, as measured over at least a 24 hour period, is at least 25 decibels (dB) below the average channel power and/or less than 20 decibels (dB) above a noise floor associated with the neighborhood node."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ingress-mitigated cable communication systems and methods having increased upstream capacity for supporting voice and/or data services","description":"Cable communication systems and methods to provide voice and/or data services to subscriber premises in one or more neighborhood nodes via an ingress-mitigated cable plant that conveys upstream inform","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8543003","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
