This is mainly an outdoor test with indoor nodes ;-) The idea is be as 
realistic as possible and try to replicate the actual village 
environment, only in its worst possible form: Including the high radio 
noise levels of MIT. We should not enforce connectivity by means of 
external antennae, but rather experiment with the reachability of the XO 
as it is, potentially by adding active antennae in between.

Having this testbed in place, we can try a mobility test also, eg. 
having a mobile phone or an XO "walk" from end to end.
