[ath9k-devel] ath9k_htc 1mbps in IBSS mode

["Nicolás Echániz" <nicoechaniz@codigosur.org>]

I'd like to bump this thread:

https://lists.ath9k.org/pipermail/ath9k-devel/2012-March/008335.html

...and add some more data and context.

Guido, myself and a group of people are involved in a project to build
community networks in small towns all over the country. It's a
project[0] from the National Ministry of Education that involves not
only the deployment of a number of nodes in each town in order to get
the networks started but also a process of theoretical and practical
training mainly targeted at young people in each town.

The networks need to meet two important characteristics:
1) easy replication of the network design
2) very low per-node cost

We have achieved the second goal with the hardware setup that Guido
mentioned but we are having difficulty with the ease of deployment due
to the increased complexity of designing mixed ad-hoc/infrastructure
networks.

We have tested a big number of usb wifi dongles but those based on
ath9k_htc have proven to be by far the most stable.

On the technical side of this issue, I can add to guido's report that in
rev.29960 of Openwrt, with the same configuration, our WN722N dongles
were capable of establishing 150Mbit/s HT mode links, although they did
not behave as stable as the internal ath9k based radios from the MR3220
routers.

With current revs of OpenWRT trunk, the behavior of ath9k-htc dongles in
ad-hoc mode has become unusable (always running at 1Mbit/s) so we are
forced to mixed mode network designs.


We are greatly interested in helping out in any way we can to help solve
this issue. We are in charge of three community network deployments that
can be used as test beds; these are at your disposal, but please let us
know if we can be of assistance in any other way.


Cheers!
