DYNAMIC MODULATION SELECTION
First Claim
1. A method performed by data processing apparatus, the method comprising:
- obtaining data specifying a baseline data rate for transmissions from a node that are received over a channel of a power line communications system;
obtaining a set of available modulation techniques for the node, the set of available modulation techniques including at least two modulation techniques with which the node is configured to encode data that are transmitted over the channel;
selecting a modulation technique for the node, the selected modulation technique being a modulation technique from the set of available modulation techniques, wherein the selected modulation technique is capable of providing data with at least the baseline data rate with at least a threshold confidence; and
providing, to the node, data specifying the selected modulation technique.

Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for transmitting data. In one aspect, a method obtains a baseline data rate for transmissions from a node that are received over a channel of a power line communications system and a set of available modulation techniques for the node. The set of available modulation techniques can include at least two modulation techniques with which the node is configured to encode data that are transmitted over the channel. Using the set of available modulation techniques, a modulation technique that is capable of providing at least the baseline data rate with at least a threshold confidence for the node is selected. In turn, data is provided to the node specifying the selected modulation technique.
