Power management for cable modems and wireless base stations
A recently granted patent (Publication Number: US12003816B2) discloses a communications method involving a Cable Modem Termination System (CMTS) providing power to multiple wireless base stations through cable modems connected to the CMTS. The method includes receiving power consumption information from individual cable modems, determining which cable modems to send a reduce power consumption message based on this information, and adjusting buffer sizes to manage power consumption effectively. The system aims to optimize power usage by controlling the operation modes of cable modems and wireless base stations, ultimately enhancing energy efficiency in communication networks.
Furthermore, the patent describes a communications system where the CMTS controls power distribution to wireless base stations via cable modems, based on power consumption data received from the cable modems. The system includes mechanisms to adjust buffer sizes, switch between power-saving modes, and manage data transmission efficiently. By implementing these methods, the system aims to improve overall network performance, reduce power consumption, and enhance the reliability of communication services. This innovative approach to power management in communication systems could lead to more sustainable and cost-effective network operations in the future.
