    Hello,

    @ radiohead.
    The kit shown works upto 1000 Mhz.
    GSM phones can work on 850, 900, 1800 or 1900 Mhz.
    Some even have Bluetooth active, wich works round 2400 Mhz.
    The kit might not catch all gsm's in the room.

    Greetings,
    Bertus

    You may find that making a device operating at 2.4 GHz is very challenging for a first-time project. Even 400 MHz layouts are hard to get right.
