Do most current Powerline adapter models use Powerpacket technology or Passport technology?
Frankly, I have never heard of Passport in conjunction with powerline network.
The few search results I got say that "PassPort" is a adapter/technology from Intelogis (a company I couldn't find on the net) and they seem to be rather old Win 95/2000 times, perform rather slow and only support Windows.
Intellons PowerPacket was the base for the HomePlug 1.0 specification.
These days pretty much all adapters are based on the HomePlug alliance specifications.
Thanks. The technology other than Powerpacket , is the technology from Intelogis and is what I was referring to.
Nice answer and is marked as 'best'
