Abstract
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 detecting a communication from foreign PLC device on a PLC network in response to a foreign preamble received by the PLC device, terminating transmissions to the PLC network for a network-specific co-existence Extended Interframe Space (cEIFS) time period in response to the foreign preamble, and resuming transmissions to the PLC network after expiration of the network-specific time period.
Claims2
A non-transitory electronic storage medium having program instructions stored thereon that, upon execution by a processor within a power line communication (PLC) device, cause the PLC device to:
- receive a co-existence preamble, wherein a native preamble was not detected;
- detect a communication from foreign PLC device on a PLC network in response to a foreign preamble received by the PLC device;
- terminate transmissions to the PLC network for a network-specific co-existence EIFS (cEIFS) time period in response to the foreign preamble;
- and
- resume transmissions to the PLC network after expiration of the network-specific time period.
A non-transitory electronic storage medium having program instructions stored thereon that, upon execution by a processor within a power line communication (PLC) device, cause the PLC device to:
- receive a co-existence preamble followed by a non-native preamble;
- detect a communication from foreign PLC device on a PLC network in response to a foreign preamble received by the PLC device;
- terminate transmissions to the PLC network for a network-specific co-existence EIFS (cEIFS) time period in response to the foreign preamble;
- and
- resume transmissions to the PLC network after expiration of the network-specific time period.
