Embodiments of methods and systems for adaptive sub-band point-to-point communication are presented. In one embodiment a method includes performing functions using a power line communication (PLC) transmitter device. The method may include generating a first data packet having a first adaptive sub-band information set, the first sub-band information set comprising information to be used by a PLC receiver for determining a sub-band hopping pattern. The method may also include transmitting the first data packet on a first PLC sub-band. Additionally, the method may include hopping to a second PLC sub-band, and generating a second data packet having a second adaptive sub-band information set, the second sub-band information set comprising information to be used by the PLC receiver for determine the sub-band hopping pattern. The method may further include transmitting the second data packet on the second PLC sub-band.
