remote control. what do you want to control exactly? to make a transmitter and reseiver circuit it's ok, but do you want also to control any operation in the cellular?? do you want to connect the receiver to your cell or it's already connected?
if so, then beleive me! 99% it wont work.
pm me please of what you need exactly. or post it. i'll send you as much information as i can
The circuit that I intend to set up,
is to control 4 or more exits trough tones DTMF correspondents of a telephone any for a receiver using a cellular phone .
I intend to tie this receiver for the call touches .
Dear José Luis
it can easly be implemented ; I have already implemented one that can work via dtmf commands .
The circuit idea is that : you call your home , after a specified nos of ringing (controlled) the line will open and wait for secret code ... according to this code , you can switch on/off unlimited no. of devices (controlled)
This can be controlled via normal phone or cellular because in both cases the commands are dtmf standard and both (fixed / cellular ) can support it
If you are interested in this circuit please pm me .

Tiny Planet is small device connected to a GSM cell phone. When the mobile receives a predefined SMS (text message), like "Activate burglar alarm" or "Start backup pump", the circuit automatically recognizes it as a command, and switches the output port accordingly. Besides switching the port on or off, the user can pulse it for a short period (e.g. “Reboot remote server”).
.
The device can be used as well to notify the status of the input port, sending automatically a message every time the input changes (e.g. "Warning, intrusion detected", "Insufficient level in Tank #5”).
To know input status at any time, the device can send back a SMS based on the status of the input, as a response to a request message.
Tiny Planet gets the most out of a 8-pin microcontroller an is remarkably simple. Text messages are customizable (despite of using less than 512 instructions of assembler code) and is simple to use: ways simpler than most GSM modems...
Even if you're not interested in building it, the article is worthing to read in order to learn more about how to connect a GSM phone to a microcontroller and how to send, receive and analyze SMS messages.
Please have a look to this site , If this what you want , tell me
because I have already finished some thing like that but using different
microcontroller
