i have a project to transmit data wireless using rf modules using 433Mhz....with AT89C51 microcontroller....plz anyone post me a assembly code for this transmission....!!!!!
If your project just requires presenting the work of others, then there are plenty of 433MHz radio modules that connect with a simple CMOS serial interface.

thanx....!!! a lot.....!!!!
Thanks for that - it answers an entirely unrelated question for me!!

I've played around with the 433 MHz and 915 MHz versions using Tridge's SiK firmware as 3DR Radios, work quite nicely, and have a good throw, shudder to think of the regulatory compliance though...
