IFindNickNamesAnnoying and Dr D: You are wrong. NB-PLC is well on its way, and selling a lot. And performing like a breeze. Ask in Spain, if you want.

Ditto on the previous comment. There is too much broadband noise in the HF spectrum already. What will this generate when connected to a infinitely large antenna system like the grid.

Please don't let this morph back into another broadband over power lines (BPL) mess. Even 500 Khz is getting a bit high for a network of wires that were designed for 60Hz power distribution. The leakage of unintended noise from BPL systems along with the intrusion of signals from real radio transmitters made that other service bad.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
