That would be excellent to have one this WBMv4.
Do you what kind of equipment is that ? Spectrum Analyzer ?

Our contact teacher (in BCC) asked for what purpose since isn't

We have tried the Ubiquity WiFi scanner w/ Aaron and this is a
good/simple way to have a view of the occupancy of the spectrum but
the full spectrum analyzer can give use advanced spectrum analyzing of
the gaussian response for each 14 802.11 channels (that will differ
from one 802.11 chip to the other and than affect the perturbations
from one channel to the other).

We can organize a day/half-day of talks/presentations including local
academic projects of Barcelona universities.
