1. yes, it goes up to 6Ghz
2. yes, and it also supports 5MHz
3. yes, it supports nv2
4. yes, it's FCC approved but not in those bands.
so there's a RB411, RB411A and now a RB411AH?
As the document says, same processor as the 433AH so this must be the fastest AP/CPE around.
I estimate the price to be about $120-$130?
