Maybe for some really small range application, for anything beyond 10m and
with more than 5 clients you need a better device.
Nest device so far for really affordable price was WR841N from TP-LINK
(around 18$). We also created and 3D printer outdoor case for it so it was
most affordable device to be put outside... otherwise outdoor devices cost
50$ onwards

OLSR is ok for up to 200 nodes, but why not just use existing solution that
JustWorks(tm) - http://nodes.wlan-si.net
Try it out and you will be probably be amazed :)

We use Babel and are probably biggest mesh network that work without issues
that others are having with using Batman and OLSR. Babel routing protocol
is only one that scales beyond 300 nodes and doesn't have lots of issues...
