[mesh-dev] 802.11 feature questions

[Marc Juul]

Hi Mitar (and anyone else really)

I'm trying to figure out how to disable just 802.11b but not 802.11g. I
know how to enable greenfield mode, but not how to just disable 802.11b

Also, a few other questions:

If I enable short guard interval, what will that do for 802.11g? Do you
recommend using it for the public "give wifi to the people" access points
in an urban environment where there will still be some older 802.11g
clients?

Would you enable 40 mhz mode for these public access points as well? If I
understand correctly then they will still be able to use 20 mhz for 802.11g
devices and 40 mhz for 802.11n devices. Correct?

If I have a 1x1 802.11n node, like a Bullet M2, will it actually help to
enable TX-STBC or RX-STBC1 ? My understanding is that RX-STBC1 will still
give an improvement but that TX-STBC will do nothing (or maybe even reduce
performance?) if you have only one transmit antenna. Is this correct?

I'm not sure I understand what DSSS_CCK-40 does? It enables support for
this mode, but under what circumstances will it actually be used?
