Abstract:
1. A communication network comprising: three communication nodes, each including a first analog filter, each configured to communicate simultaneously and independently over a power line with the other two communication nodes using a plurality of widebands, wherein a high band of the plurality of widebands has a minimum frequency greater than 30 MHz, wherein a low band of the plurality of widebands has a maximum frequency of about 30 MHz, wherein the first analog filter of each communication node comprises a low pass filter, and wherein each of the three communication nodes is configured to transmit signals in the low band with a low band transmission power spectral density and configured to transmit signals in the high band with a high band transmission power spectral density and wherein the low band transmission power spectral density is approximately one thousand times greater than the high band transmission power spectral density.
