Abstract
Systems for channel selection in power line communications (PLC) are described. In some embodiments, a PLC device may include a processor and a memory. The memory stores instructions executable by the processor to cause the PLC device perform operations. One or more time slots in each of a plurality of frequency bands are sequentially scanned. A packet transmitted by a second PLC device to the PLC device over one of the plurality of frequency bands is detected. Additional packets received from the second PLC device are synchronized across the plurality of frequency bands based, at least in part, upon the detected packet. The additional packets are organized in a plurality of frames. Each of the plurality of frames having been transmitted by the second PLC device to the PLC device over a respective one of the plurality of frequency bands. Each frame has a plurality of time slots, and each time slot has a pair of beacon and bandscan packets.
