Abstract
A method of powerline communications between a plurality of nodes on a powerline communications (PLC) channel including a first node and a second node. At least one communication quality measure is determined for the PLC channel. Based on the communication quality measure, a preamble of a data frame is dynamically switched between a reference preamble having a reference symbol length including a reference number of syncP symbols and a reference number of syncM symbols and at least a first extended preamble having an extended symbol length that is greater than (>) the reference symbol length. The data frame is then transmitted on the PLC channel.
