>> what is the difference with the current RocketAC that already has the Prism >> system in it?
The RocketAC-Prism has three important new things going on from what I can tell: - TX filtering.. lower OOBE emissions mean higher power on channels closer to the band edge - Expanded RX filtering range.. Old prism was 5480-5850, new prsim is 5150-5850 - GPS Sync is back.. unknown benefits, time will tell.
