[nycwireless] measuring cellular activity?

2004-10-06 Thread Anthony Townsend
i'm in need of a circuit/device/meter that can listen on different 
bands - mainly digital cellular - and output a measure of aggregate 
activity on that band.

the goal is to build a simple device that can somewhat accurately 
measure how many people are talking on cell phones in the general 
vicinity... this will become part of a public art project.

i saw the Mythbusters on TV using a microwave oven leak detector to 
measure power output from a cell phone. not sure if there are better 
ways to do it.

any leads from the RF geeks on this list?
thanks

I have no idea if this is useful to you but it sure looks interesting:

There other products look cool too, and some/most seem to be able to 
hook up to a PC.

One indirect way you might want to investigate thru back issues of 2600 using older 
telephones:

Some Nokia telephones have a diagnostic mode that let's you see all the telephones 
being dialed into the reverse channel. If you can see all the phone numbers going into 
the cell site, you can infer one phone per cellfone. If there are multiple attempts, 
someone is retrying the number.

All the gear you need is a specific model Nokia cellphone and a pc for data 
collection. The funny thing is if there is a crime or accident in the area, you can 
tally all the 911 calls.

 The info comes out a common serial comport that is a standard for most contempoaray 
pcs.

If you don't have access to any 2600 issues, you can hear the radio show Off the hook 
at the 2600.org site. You can dwnload the show or order all the mp3s on one DVD.
