Why it doesn’t support 802.11 Turbo mode ?
It’s a software or hardware limit?
I don’t think any of the 802.11n cards support turbo mode.
40MHz chanel bonding:
ht-extension-channel (above-control | below-control | disabled)
The current 802.11n draft supports a method of channel bonding for both 2.4Ghz and 5.Ghz systems. There is 1 20Mhz channel defined as the “control channel” while the secondary channel can then be set to sit above or below the control channel. Seeing as 2.4Ghz only has 3 ‘usable’ channels (1,6,11) its recommended to use this on a 5Ghz where there are more available channels.
This is not compatible with turbomode.
I need much more bandwidth on ptp link
If I replace my ptp link with “N cards” and after this I’ve not stable link,
the only thing I can do is set Turbo mode but if the cards doesn’t support
it I have to physically go to replace them.
My question is:
does, this card, support 802.11a Turbo mode in future? Is technically possibile?
Thx
No. It does not support Turbo.
If you can get N working properly, it is faster than Turbo.
Give some details on your link, maybe we can help get it stable.
What version ROS? Frequency, signal, etc…
Use N mode..
I have a stable link with 2x RB433AH + R52n cards - 5km distance - 95mbits real speed.
If you have more than 150 clients n the other side of the link , consider using RB800 or a P4 machine.
