Dualband mesh access point

Hello!
I would like to know whether it is possible to build an dual-band access points using Roter boards with this http://www.ubnt.com/xr9 and this http://www.ubnt.com/xr2 type of wireless interfaces with MESH network compatibility for both of radios?

It shouldn’t be a problem.

So what type of routerboard you recomend for it and how can it be configured?

I would use like this http://shop.mpl.com/routers/12-router-board-433ah.html

There are many different ways to do a configuration like this and without know exactly what you are doing its hard to point you in a specific direction. But here are a couple wiki pages for mesh.

I think it’s going to look like point to multipoint connection. These system is going to be used to build some sort of war-control network with rc models of airplanes/tanks/etc with advansed reality system and IR lasers as a weapon system. So i need all ground/air/water based machines to be connected everything to everything.
