Digital narrow band power line communication system

摘要

A method and system for providing low cost narrow band digital power line communication using OFDM-like protocols to promote spectral diversity, reduce data loss, and provide higher data throughput. This invention provides a specific design to accommodate the requirements of a wide variety of communication applications and is adapted to make use of an AC power line communication within a building or facility without requiring dedicated hard wiring and does so with the advantages of OFDM but without the high costs of OFDM.
