Multi-wideband communications over multiple mediums within a network
View Patent ↗A powerline communications device comprises a powerline communications interface and at least one other communications interface configured to communicate over a computing network. The powerline communications interface is further configured to receive electrical power. The computing network may comprise mediums including powerlines, telephone lines, and/or coaxial cables. In some embodiments, the powerline communications interface may communicate with a network apparatus, such as a personal computer, via an Ethernet interface. The powerline interface, the telephone line interface, and/or the coaxial cable interface may all be associated with the same media access control (MAC) address. The powerline communications device may receive a message via a first medium and repeat the message via a second medium based on a quality of service (QoS) metric. In some embodiments, the powerline communications device may communicate using multiple frequency bands.
1. A powerline communications device, comprising:
a network processor comprising logic configured to determine whether to alternatively communicate a message via a powerline communications interface or a second communications interface, the second communications interface being configured to communicate via a telephone line or a coaxial cable, both the powerline communications interface and the second communications interface being identified by a same media access control address; and
a host interface controller configured to be shared by communications received through the powerline communications interface and the second communications interface.
2. The powerline communications device of claim 1 , wherein the second communications interface comprises a telephone communications interface.
3. The powerline communications device of claim 1 , wherein the second communications interface comprises a coaxial cable interface.
4. The powerline communications device of claim 1 , wherein the logic is further configured to determine whether to communicate the message via a third communications interface identified by a second media access control address.
5. The powerline communications device of claim 1 , wherein the host interface controller includes physical and data link layers of the OSI reference model.
6. The powerline communications device of claim 5 , wherein the host interface controller further includes the network, transport, and application layers of the OSI reference model.
7. The powerline communications device of claim 5 , wherein the powerline communications device is configured to act as a switch at the data link layer level responsive to the logic of the network processor.
8. A network comprising:
a first section of mains cable configured to provide AC power;
a second section of mains cable configured to provide AC power and connected to the first section of mains cable main via a junction box;
a telephone network;
a first device configured to receive a message via the first section of mains cable and forward the message via the telephone network; and
a second device configured to receive the message from the first device via the telephone network, and to forward the message via the second section of mains cable.
9. The network of claim 8 , wherein the first device is configured to shift the message from a first frequency band to a second frequency band.
10. The network of claim 8 , wherein the first section of mains cable is on a first alternating current (AC) phase and the second section of mains cable is on a second alternating current (AC) phase.
11. The network of claim 8 , wherein the first section of mains cable comprises a ring main.
12. The network of claim 8 , wherein the first section of mains cable comprises a spur.
13. A method comprising:
generating a message;
transmitting the message via a first section of mains cable connected to a second section of mains cable via a junction box;
receiving the message at a first device;
forwarding the message from the first device, via a telephone line or a coaxial cable;
receiving the message from the first device, at a second device; and
forwarding the message from the second device, via the second section of mains cable.
14. The method of claim 13 , further comprising shifting the message from a first frequency band to a second frequency band at the first device or the second device.
15. The method of claim 13 , wherein the first section of mains cable and the second section of mains cable are on different AC phases.
16. A network comprising:
a first section of mains cable configured to provide AC power;
a second section of mains cable configured to provide AC power and connected to the first section of mains cable via a junction box;
a coaxial cable network;
a first device configured to receive a message via the first section of mains cable and forward the message via the coaxial cable network; and
a second device configured to receive the message from the first device via the coaxial cable network, and to forward the message via the second section of mains cable.
17. The network of claim 16 , wherein the first device is configured to shift the message from a first frequency band to a second frequency band.
18. The network of claim 16 , wherein the first section of mains cable is on a first AC phase and the second section of mains cable is on a second AC phase.
19. The network of claim 16 , wherein the first section of mains cable comprises a ring main.
20. The network of claim 16 , wherein the first section of mains cable comprises a spur.
