[nycwireless] Question about RF signal detection ...

[Jon Baer]

Ive seen a large number of wireless cam detectors where the cams operate on 2.4 level and other counters ... things like these:

My question is after reading the PDF article on Open Spectrum is that it labels 2.4 as the "junk band" because so much appliances run along this unlicensed band, but what I want to know (not being an RF engineer obviously) is if there is anyway to tell or identify a signals identification. Many of the "bug detectors" are really short distance readers (maybe 5-10 feet at the most), but do they work out in the open as to things which can detect that a possible 802.11 based signal is available? Id like to know if you could without a laptop, pda, or card detect a possible hotspot.

I am guessing that if you are out in the open beyond cordless phones, microwaves, baby monitors, that it is a safe bet you would be sitting in a hotspot if the signal is strong enough to set off an RF detector. Im assuming there is no way to detect or label a signal either, which I find to be a shortcoming if its not possible. Hoping someone with experience in RF detection (and direction) could enlighten me on this subject.

Thanks.
