[ath9k-devel] Open source wifi router for crisis situations using ath9k

[Valent Turkovic]

Hi all,
I'm one who starter www.meshpoint.me - idea is to build open source
wifi router that can be easily deployed in any type of crisis
situations.

I have been setting up wifi networks in crisis situations and I know
that there are no devices that are usable in crisis stiations. Belive
it or not but first responders usually aren't network admins :)
So that is why we started developing MeshPint.

First iteration will use off the shelf components and later we plan
develop our own wifi router board using atheros hardware.

Our current design (as you can see on the web site) uses three TP-LINK
WR842ND (AR9341) boards in 3D printed case.

Our concern is that this could generate too much interference and
cause too much L2 retransmissions because of co-channel interference.

We are using latest OpenWrt 15.04 Chaos Chalmer and ath9k driver and
would like to know if it is possible to extract metrics that shows
number or L2 retransmissions.
Do mac80211 or ath9k tracks L2 retransmission statistics?

How can we get those metrics if they do?
