How many channels are available in 5GHz spectrum to deploy AC wave 2 APs (3802i) in it's full capacity

[Parmanand Patil]

How many 40-MHz,80-MHz & 160MHz channels are available 5GHz spectrum in US (new -B regulatory domain) & India ?

with available 80MHz or 160MHz channels, can we plan high density wireless over-voice & video?

what are expected limitations will run into US & India regulatory domains currently ? 

Thank you,

Parmanand

In the US the new b-regulatory can be seen on:

Which brings the total possible 80MHz channels to 6, and 160MHz channels to 2.
