Chirping Cell Phone Near Field Receivers

A new thing with highly modified cell phones has arrived. Imagine a cell
phone with a built-in near field receiver (also called close-up TSCM gear). Cell phones make various different chimes for phone calls, texts, and people
of particular importance, so hearing a chirping sounds would not be unusual. The closer the cell phone is to the device emitting EM radiation the more the phone would react. Or you could hear one type of chirp and a wholly other chirp for a closer reception.
Cell phones nowadays are basically small computers with multi-function capabilities. This is just one more way to extend/expand the functionality of this ubiquitous electronic device. Smart phones are the spooks best friend. They don't attract attention and they can do many many things.
To level it up to a whole new level would be to pair a small set of ear buds to the cell phone and only hear the chirps through the headphones via bluetooth, keeping the fact of reception hidden from people nearby. The phone would need to be modified to cut out the frequencies used by bluetooth, but that would be a small feat for a software-defined radio inside of the cell phone. Now you have just one more feature on your thousand dollar cell phone; making the phone actually be worth a thousand dollars, what it computes is now arbitrary... if you can imagine it there is probably some way that your phone can make it happen, for better or for worse.
One thing to note is that Android cell phones are based on the Linux operating system. That means if you can write code for Linux/64 you could easily port it to (make it compatible with) to Android. Now that is an all-star performance.
Cheers!
