This is a last-mile solution. At least in our town its symetrical connectsions at 512k 1.5meg and 3.0 meg. But then again we have a BPL/wireless hybrid.
A report on its performance would be appreciated by all, I am sure. What kind of speed does it get in practice? How does that change during peak times? What percentage of the time is it up? What city? The hybrid sounds like an Amperion system. PPL is in the process of taking them out of most areas of their Allentown, PA system.
