I was thinking to use two different types of antennas, one in Hpol and
the other in Vpol. For instance, a slotted waveguide and a simple
colinear.

This way, you can be sure that there is less interference.

I will try to simulate the behaviour of OLSR with UML-wifi, but I need
to find an x86 box with enough ram to get several nodes running.

Does someone has already tried uml-wifi + olsr here?
