-operate at 1200 bits per second baud rate
-use many caps in the circuit
-use an antenna

so what error rate are you getting?

you'll never get 100% success rate with uncorrected RF modules.
some sort of error correction will be needed.
try reading up on Cyclic Redundancy Checks.

hi
       the modules that i have written that 9600 baudrate but i am using it on 4800 .does it create any problem.

[benji]

if it says you should operate at 9600 then why operate at 4800 ?
sure try the 9600 bps
