Abstract

Systems and methods for reducing the latency and for increasing throughput for MoCA devices that are connected via a coax network are provided. One method according to the invention includes, in a network having a plurality of network modules, each of the plurality of network modules being connected to a coax backbone, communicating over the coax backbone between the plurality of network modules. The method further includes a requesting the use of short burst messages. The method further includes responding to the requesting by constructing a short burst message with a single channel equalization section and reducing the number of bits per hertz in the transmission constellation. The resulting messages can be received with an acceptable error rate while making more efficient use of the MoCA network.

Claims (31)

1. A networked node for use in a network, configurable to request a message comprising a short preamble, the network comprising a plurality of network nodes, the networked node comprising:

a receiver which is configurable to receive a message containing the short preamble, the short preamble comprising a single channel estimation section; and

a transmitter which is configurable to transmit a request for a message containing the short preamble.

2. The networked node of claim 1 , wherein the message is a reservation request message.

3. The networked node of claim 1 , wherein the message is an ACK message.

4. The networked node of claim 1 wherein the node is further configured to request utilization of a reduced constellation while transmitting the message.

5. The networked node of claim 1 , wherein the short preamble further comprises a cyclic prefix section.

6. The networked node of claim 1 , wherein the short preamble comprises between about 672 samples and about 736 samples.

7. A method for communicating over a network, the network comprising a plurality of network modules, the method comprising:

requesting reception of a first short burst message comprising a short preamble; and

receiving the first short burst message,

wherein the first short burst message comprises a single channel estimation section or the short preamble comprises between about 672 samples and about 736 samples.

8. The method of claim 7 , wherein the first short burst message comprises the single channel estimation section.

9. The method of claim 7 , wherein the first short burst message is a reservation request message.

10. The method of claim 7 , wherein the first short burst message is an ACK message.

11. The method of claim 7 , further comprising transmitting a second short burst messaging comprising a short preamble.

12. The method of claim 7 , wherein the short preamble comprises a cyclic prefix section.

13. The method of claim 7 , wherein the short preamble comprises between about 672 samples and about 736 samples.

14. A method for facilitating communication over a network, the method comprising:

requesting reception of a first short burst message comprising a short preamble; and

receiving the first short burst message,

wherein the requesting reception of the first short burst message comprises requesting reception of the first short burst message comprising a reduced constellation.

15. A node for use with a network, the node comprising:

a transmitter which is configurable to transmit a requested message comprising one of a plurality of types of preambles, at least one of the plurality of types of preambles comprising a short preamble; and

a receiver which is configurable to receive a request for a message, the request indicating the one of the plurality of types of preambles,

wherein the short burst preamble comprises a single channel estimation section.

16. The node of claim 15 wherein the message is a reservation request message.

17. The node of claim 15 wherein the message is an ACK message.

18. The node of claim 15 wherein the node utilizes a reduced constellation while transmitting the message.

19. The node of claim 15 , wherein the short preamble further comprises a cyclic prefix section.

20. The node of claim 15 , wherein the short preamble comprises between about 672 samples and about 736 samples.
