Hi,
For one of my projects I have done serial communication between 89C52 and 89C2051 microcontrollers through the RXD, TXD pins. Can anybody pls suggest a method to make this communication wireless with minimum modifications.

If the two micros in the vicinity then I would simply use an IR protocol & transfer the data.

If I need more distance then I use license free wireless RF modules to transfer the data.

Can you be little more specific please? Is there any standard RF module readily available suitable for this purpose? Any idea?

You're welcome....I would have suggested a chip but very few are convenient for hand assembly any more.
