Multi-wideband communications over power lines
View Patent ↗Systems and methods for communicating over a power line are configured to substantially simultaneously communicate over a plurality of wideband frequency ranges. Signals may be communicated two or from a communication node at two different frequencies simultaneously. These signals may be exchanged with different nodes and/or include independent data. In some embodiments, some of the wideband frequency ranges are above 30 MHz.
