Systems and methods for channel selection in power line communications (PLC) are described. In some embodiments, a method may include defining a plurality of frames, each frame having a plurality of time slots. The method may also include assembling a pair of beacon and bandscan packets within each of time slot of each frame. The method may further include sequentially transmitting each of the frames over a corresponding one of a plurality of different frequency bands. In some implementations, each bandscan packet may include a slot index indicating a position of its time slot within its respective frame and/or a band index indicating one of the plurality of different frequency bands. In response to having transmitted the plurality of frames, the method may include receiving one or more packets indicating a selection of one or more of the plurality of different frequency bands to be used in subsequent communications.
