Linux Working On 5MHz, 10MHz Wireless Support
On Monday the sixth revision to the Linux wireless 5/10MHz channel patch-set was published by Simon Wunderlich. This patch-set consists of 18 patches and nearly a thousand lines of new code for supporting 5 and 10MHz channels in the Linux wireless networking area of the kernel.
The patch-set adds 5MHz and 10MHz channel support to nl80211/cfg80211/mac80211 and then the Atheros ath5k and ath9k are the first Linux kernel drivers to take advantage of this support, which already support it on the driver side.
Among the expressed advantages of supporting these wireless channels are for allowing long shot links with more robust transmissions, future support for 802.11y, future support for 802.11p, and other specialized networking environments.
Those interested in Linux wireless and wanting to explore more can see these patches that will hopefully be primed for merging into an upcoming Linux kernel release, but it's now out of the window for 3.11.
