According to the spec, a VHT STA must support 80 MHz:
802.11ac-2013, 22.1.1:
A VHT STA shall support the following features:
[...]
- 20 MHz, 40 MHz, and 80 MHz channel widths
Consequently, there's no bit indicating whether or not 80 MHz bandwidth
is supported (like there is, for VHT, indicating 40 MHz is supported or
not.)
Also it is invalid to advertise a VHT capabilities IE and an HT
capabilities IE without 40 MHz.
