Abstract
Aspects are directed to communicating data over power distribution lines carrying alternating current, using a communication protocol for communicating data between endpoint devices and an upstream data-collecting device. From first symbols having a plurality of bits, at least two second symbols are generated, the second symbols respectively including different subsets of the bits in the first symbol. Each first symbol is split into second symbols having a predefined bit size for an encoding operation that operates on entire symbols having the predefined bit size (e.g., smaller than the bit size of the first symbols). The second symbols are encoded and combined according to the communication protocol. The encoded symbols are communicated over the power distribution lines based on timing indicated at least in part by the alternating current.
