How do GSM, Bluetooth and WiFi look like?

I did a 5 min recording of the audio signal of the GHz scanning device. By sending SMS, downloading images via bluetooth from a mobile phone to a laptop and activating the integrated AirPort I created typical artefacts in the GHz Space. After this I did an import of the audio file into AUDACITY which is a cool open-source audio editor. The big bursts in the first half are the SMS messages going out and coming in. In the middle you can see the bluetooth session. And at the end the fine lines results from activating bluetooth at a mobile phone and the bursts at the end result from activating/deactivating the WiFi of the laptop. So much for the indoor test case. But basically this is the principle for my out-of-the-lab recording of connectivity signales in urban areas.
