I've already looked at the costs - thankfully AR9003 radio modules are not very expensive. I'm also aware of the various RF considerations with all those radios co-located. If you or anybody wants to discuss my goals in more detail, please contact me off-list. I'd be happy to share with you more, but I don't want to get too far off-topic on the mailing list. Back to the question: anybody have thoughts on potential design limitations? ___ ath9k-devel mailing list ath9k-devel@lists.ath9k.org https://lists.ath9k.org/mailman/listinfo/ath9k-devel

Let me see if I have a DWA-552 in my collection of PCI NICs. I'll see about spinning up an ath9k test box.

[ath9k-devel] ath9k stalls every 30 seconds unless disable_ani = 1
Hi all, I just read Robert Högberg's thread on this mailing list and just wanted to verify that the exact same problem happens with my wireless NIC too. I compiled ath9k using compat-wireless. My card has the AR5008 chipset and is PCI. The vendor is D-Link, I believe the model is DWA-552. As soon as I echo 1 into disable_ani the problem goes away. Hope this helps development, let me know if any more details are needed. Caleb ___ ath9k-devel mailing list ath9k-devel@lists.ath9k.org https://lists.ath9k.org/mailman/listinfo/ath9k-devel

US Amateur also have privileges in the 5cm band which overlaps the the 5 Ghz ISM band. We are secondary users of this band with little power restriction other than not causing interference to other user of this spectrum. It would be nice to see a open source solution without having to buy more expensive commercial gear.

One of the things that would be useful as a result of doing this work would a standard way for people with licences to extend the range as defined by CRDA. In the case discussed here it is a HAM licence for frequencies below 2.4GHz, in my case the area of interest is what is known as Band C here in the UK at 5.8GHz. You do need a licence (£1 per station per year to a minimum of £50 per year) from Ofcom (our FCC) but it is easy to obtain. The 5.8 band users are also allowed more power than you would be in the normal 802.11a band. Once that standard way (preferably without rebuilding the kernel) has been defined it should be made public with lots of caviats written around it saying that this can only be used if you posess a licence and that you are personally liable for its misuse.
