I'd like to help set up the mobile power supply for spectrum mapping. were you
thinking of tying it to GPS points or how do you want to arrange the data?
cheers,

So, as some of you know, Jenny and myself have invested in the following hardware:
5 ghz 802.11n hardware:
4x Bullet M5 HP - 150 mbps - needs external antenna
1x Nanostation M5 - 300 mbps - semi-directional panel antenna
1x Nanobridge M5 high-gain - 300 mbps -
directional parabolic antenna

Here are my experiences with the gear so far.

it that makes it unusable after flashing. It should be easy to recover from using the
serial console though.

the original firmware has a really cool feature. It's a frequency analyzer for the 5
ghz spectrum that will allow us to find out which parts of the spectrum are most free of
noise and other signals in different areas. We could mount one of these Bullets on a pole
on a bike with a battery and then bike around Oakland to create a map of how much
interference we'll be dealing with in different areas! I put some info on it on the
wiki:

As a side note, it seems like the Freestation routers might be going out of
production. Some sellers stopped selling them and the price has dropped to $60 for the 2.4
ghz models and $70 for the 5 ghz models. That's a bit sad, as they seem like a pretty
good deal, but maybe that means we'll be able to get them for cheap.
