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. p. -- Polychronis Ypodimatopoulos Graduate student Viral Communications MIT Media Lab Tel: +1 (617) 459-6058 http://www.mit.edu/~ypod/ _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
