Abstract
A communication circuit supports a first communication protocol and a second communication protocol that is different from the first communication protocol. A number of signals include first signals conveying first information messages and second signals conveying second information messages. The first information messages include a repetitive message having fixed repeated content and the second information messages include a non-repetitive message having variable content. The first signals and the second signals are transmitted via the communication circuit using the first communication protocol for the first signals and the second communication protocol for the second signals.
Claims24
A method, comprising:
- having a plurality of signals, including first signals conveying first information messages and second signals conveying second information messages;
- determining that the first information messages comprise a repetitive message having fixed repeated content, and, based thereon, transmitting the first signals in accordance with a first communication protocol over a powerline communication, wherein the first communication protocol comprises frequency shift keying (FSK) modulation or spread frequency shift keying (S-FSK) modulation;
- and
- determining that the second information messages comprise a non-repetitive message having variable content, and, based thereon, transmitting the second signals in accordance with a second communication protocol over the powerline communication, wherein the second communication protocol is different than the first communication protocol, wherein the second communication protocol comprises phase-shift keying (PSK) modulation or quadrature amplitude modulation (QAM).
A device, comprising:
- a first communication circuit configured to communicate first signals conveying first information messages in accordance with a first communication protocol, wherein the first information messages comprise a repetitive message having fixed repeated content, and wherein the first signals are communicated over a powerline communication;
- and
- a second communication circuit configured to communicate second signals conveying second information messages in accordance with a second communication protocol, wherein the second information messages comprise a non-repetitive message having variable content, wherein the second communication protocol is different than the first communication protocol, and wherein the second signals are communicated over the powerline communication, wherein the first communication protocol comprises FSK modulation and wherein the second communication protocol comprises phase-shift keying (PSK) modulation or quadrature amplitude modulation (QAM).
A method of communicating, the method comprising:
- sending uni-directional first signals toward a communication signal node using a first communication protocol over a powerline communication, wherein the uni-directional first signals include first information messages that comprise a repetitive message having fixed repeated content;
- and
- exchanging bi-directional second signals with the communication signal node using a second communication protocol that is different than the first communication protocol, wherein the bi-directional second signals include second information messages that comprise a non-repetitive message having variable content, and wherein the bi-directional second signals are exchanged over the powerline communication.
