I want to build a small device that will detect the relative strength of wifi, cell/gsm and radio signals within say a 10ft radius. I want to sonify each signal so that wifi signals have a certain sound that gets louder as the signal strength increases, cell does the same with a different sound, radio ditto etc.
I've looked a lot over the forum and beyond but it seems that being able to isolate and separate the types of frequencies is problematic - do any of you out there have a solution for this?

Each of these signal types encompasses a wide range of frequencies and channels and you will have multiple overlapping signals of varying strengths - not a single signal that you can associate with a single sound. If you want to combine each of these into a single signal strength value I suppose you will need an RF band pass filter and then a circuit to measure the total power coming out of the filter. That seems like an RF design issue rather than a microcontroller design issue. I'm sure it's possible, but the Arduino forum probably isn't a good place to find how to do it - you might find better help on a ham radio forum.
WiFi will only resonate at 2.4GHz or 5GHz. Anything other than that is not WiFi. Cell Phones I am not sure but hopefully now you have a starting point.
Hmm, sounds like I need to limit this somewhat - filtering bunch of different RF signals would present problems. Maybe focus just on wifi signals - would any of the Arduino wifi options give information like connection name and signal strength (much in the same way that laptops do)?
