Power boost in communication system
Representative implementations of devices and techniques provide communication between networked nodes operating on a communication network medium. In an implementation, a node generates a broadcast frame that includes at least a preamble and a payload. The preamble of the broadcast frame may include auxiliary information. The auxiliary information may be associated with one or more symbols of the preamble. The auxiliary information may contain power boost information.
1. A method, comprising:
decoding, at a node, a mobile application protocol (MAP) physical layer (PHY) frame, the MAP PHY frame including one or more symbols carrying auxiliary information that includes power boost information and further includes one or more rules defining usage of the power boost information,
wherein the one or more rules indicates that one or more symbols is to be power boosted if a frame length is equal or greater than a frame length value defined in the one or more rules,
generating a data frame, the data frame including particular symbols set at a boosted power level in accordance with the power boost information of the auxiliary information, wherein particular symbols comprises symbols set at a boosted power level on a per symbol basis, and
transmitting the data frame.
2. The method of claim 1 , wherein the one or more symbols at the power level in accordance with the power boost information of the auxiliary information are at least associated with a preamble of the data frame.
3. The method of claim 1 , wherein the one or more symbols at the power level in accordance with the power boost information of the auxiliary information are at least associated with a header of the data frame.
4. The method of claim 1 , wherein the one or more symbols at the power level in accordance with the power boost information of the auxiliary information are at least associated with a preamble and a header of the data frame.
5. The method of claim 1 , wherein the act of generating the data frame includes power boosting the one or more symbols from a first power level to second power level based on the power boost information of the auxiliary information.
6. A system, comprising:
a communication network medium, and
at least one node coupled to the medium, the node arranged to communicate, at least in part via the medium, a frame that includes power boost information and further includes one or more rules defining usage of the power boost information,
wherein the one or more rules indicates that one or more symbols is to be power boosted if a frame length is equal or greater than a frame length value defined in the one or more rules,
wherein the power boost information indicates particular symbols are power boosted in that frame, and
wherein particular symbols comprises symbols power boosted on a per symbol basis.
7. The system of claim 6 , wherein the communication network medium comprises a network of electrical power distribution conductors.
8. The system of claim 6 , wherein the power boost information includes a power boost value in decibel (dB).
9. The system of claim 6 , wherein the frame comprises at least a preamble portion, the preamble portion to carry the power boost information.
10. The system of claim 9 , wherein one or more symbols of the preamble portion carry the power boost information.
11. The system of claim 6 , wherein the frame comprises at least a header portion, the preamble portion to carry the power boost information.
12. The system of claim 11 , wherein one or more symbols of the header portion carry the power boost information.
13. The system of claim 6 , wherein the frame is a broadcast message, the broadcast message for transmission to a plurality of nodes coupled to the communication network medium.
14. The system of claim 13 , wherein the broadcast message is a mobile applications protocol (MAP) physical layer (PHY) frame communication.
15. A node, comprising:
a controller, and
a storage memory coupled to the controller and including instructions to generate at least one communication for communication on a communication medium when executed by the controller, the at least one communication to include:
a first portion to carry auxiliary information, the auxiliary information including at least power boost information and one or more rules defining usage of the power boost information,
wherein the one or more rules indicates that one or more symbols is to be power boosted if a frame length is equal or greater than a frame length value defined in the one or more rules, and
wherein the power boost information indicates that particular symbols are power boosted, wherein particular symbols comprises symbols power boosted on a per symbol basis, and
a second portion to carry payload data.
16. The node of claim 15 , wherein the auxiliary information further includes at least one rule defining usage of the power boost information.
17. The node of claim 16 , wherein the at least one rule indicates that the power boost information is to be used to change a power level of one or more symbols in a communication for transmission on the communication medium.
18. The node of claim 15 , wherein the power boost information is a decibel value.
