You let me wonder? What do you mean by modem?!

and what type of messages you seek to send/receive?

and, do you want to communicate wireless or via wire?

Your idea maynot be crazy

hai potetojb,
Even I am trying to design a modem.But even I am not sure if it would work.I am doing using matlab first and then burn it to dsp processor.
But according to me even it can be done using microcontroller.So its not a crazy idea u can go abt it.U can also try coding in vhdl and burn it onto fpga.

But what did u mean when u said modem shouldnot be in same place?

Best of luck.
