    Hi..
    Currently started android development and came up with an idea to my first android app which would be to capture signals in a given range of frequencies.
    My question is:
    1) If this is possible first of all? And if so can i use for instance the phone's antenna, wifi or bluetooth to do this?
    2) Which api to use in order to get the signal from the above given input device?
    3) Any suggestion on how to achieve this?


    PS: I'm new here so if I placed my post in the wrong area, kindly move it to the right place.

    Any help or suggestion in the right direction is greatly appreciated.

    Thank you

    Without physically modifying the antenna in question, it wouldn't be possible to use them as a spectrum analyzer. At the very least you would need a third party dongle that doesn't implement a bandpass filter.

    That i understand but lets say that the signal is in a range of 1200 - 1800Mhz,
    which is the range of wireless phone networks. How would i capture that signal?

    The Radio chips in phones are specifically designed for phones - you can get voice or data out of them - that's all.

    So meaning that if you know which frequency voice or data is being transmitted on, you can get access to it or not??
