Patent number: 10938478Abstract: Dynamic power in cable access networks may be reduced. First, a peak data rate associated with a network may be determined. Then, a modulation order and an associated Radio Frequency (RF) level that will support the determined peak data rate may be determined. Next, a power value to be transmitted by a node in the network based on the determined modulation order and the associated RF level may be determined. A bias value may then be determined for the node to support the determined power value.Type: GrantFiled: August 16, 2019Date of Patent: March 2, 2021Assignee: CISCO TECHNOLOGY, INC.Inventors: John Holobinko, John Alexander Ritchie, Jr.

Patent number: 8310600Abstract: Non-harmonically related carriers may be provided for signals entering a harmonically related carrier (HRC) network. A modified carrier frequency may be assigned for any and/or all harmonics of a reference frequency. The modified carrier frequency may be computed by determining a nearest multiple of an index frequency value to the nominal harmonic frequency.
