Aren interference problems with BPL a thing of the past as first generation systems had problems, but the second generation systems today have fixed the interference problems?
Regardless of the modulation technique or feedpoint technology used, the base medium is still unshielded power lines which will radiate on whatever frequencies are used in the system. Two equipment vendors, Motorola and Current Technologies, have shown systems with superior frequency notching capabilities and are much more proactive in preventing interference problems.
Whatever improvements were made in the second generation systems we see today, it has not fixed the problems. Field measurements have shown interfering emissions levels and regardless of the modulation technique or feedpoint technology used, the base medium is still unshielded power lines which will radiate.
