ENABLING CO-EXISTENCE AMONG POWER LINE COMMUNICATION (PLC) TECHNOLOGIES

摘要

Systems and methods for enabling co-existence among power line communications (PLC) technologies are described. In some embodiments, a method performed by a PLC device, such as a PLC gateway, may include searching for and detecting a co-existence preamble on a PLC network while not transmitting or receiving frames. The device waits a time period before attempting transmission of a frame if the coexistence preamble is detected and is not followed by a native preamble. Transmissions are resumed to the PLC network after expiration of the time period.
