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.
Claims22
A method comprising:
- performing, by a power line communication (PLC) device,
- 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 time period in response to the foreign preamble;
- and
- resuming transmissions to the PLC network after expiration of the network-specific time period.
A power line communication (PLC) device, comprising:
- a processor;
- and
- a memory coupled to the processor, the memory configured to store program instructions executable by the processor to cause the PLC device to:
- 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 time period in response to the foreign preamble;
- and
- resume transmissions to the PLC network after expiration of the network-specific time period.
An 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:
- 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.
