Can MT be used (with a cm9 or sr5) card as a passive 2.4ghz listener? I don’t want to be broadcasting beacons or associating with any access points.
I want to monitor the noise levels at one of my tower sites and keep track of receive signal levels of various wifi APs. I know I can use /int wireless scan to compile a list of APs.
SR5’s are 5 GHz not 2.4 GHz. Maybe you mean SR2.
I have to wonder if is will cause interference or if it is truly only listening with these scans. NO! I would think!
There are some nice Linux programs for scanning but you have to run them on a PC, like The Auditor security collection. It’s a live CD. You really should check it out! It’s great for checking your networks security.
yeh, sr2 would indeed be better. Maybe I’ll get one and hook it up to my spectrum analyser to see when it’s “putting out”
I don’t use wifi or plain 802.11/a/g for my network, so I don’t need to spend time evaluating my own security with tools made for those systems. I was just hoping to track new access points of other people, their dates of deployments, receive signal levels, and how the signal levels change over time. (zero interest in snooping their traffic)
I don’t trust the signal level measurements using my notebook with netstumbler and a usb thumb wireless adaptor. A real radio on a tower like MT with a known-gain antennna seems more accurate.
I have massive quantities of alvarion 2.4ghz frequency hopping (and other things at other frequencies) at my tower sites which are pretty wifi unfriendly. Without inadvertenty causing any self interference, I want to know about wifi use in my community without transmitting or hurting my security by communicating with other networks.
