Have you tried interoperating with FreeBSD? Have you tried interoperating with some of the atheros AP builds that are out there? I'd like to do some interoperability tests with this at some point soon just to ensure things aren't too crazy. thanks, Adrian On 15 May 2013 07:18, Simon Wunderlich <simon.wunderlich@xxxxxxxxxxxxxxxxxxxx> wrote: > This patchset adds support for 5 and 10 MHz in nl80211/cfg80211/mac80211 > and enables support in ath5k and ath9k, which already support this feature > on the driver side. 5 and 10 MHz wide channels might be useful for: > > * long shot links, as the transmissions are more robust > * future support for 802.11y which allows some 5 and 10 MHz channels in > 3.6 GHz range > * future support for 802.11p which uses 10 MHz in 5.9 GHz range > * ... and more "special" applications. > > This patchset enables 5 and 10 MHz channels only for OFDM, and without > HT/MIMO/aggregation (for now).
