Dear Frineds,

I have to create a RF communication between two distant microcontrollers, i.e upto 700 meters. I am aware of the microcontrollers but i want to know some details about the RF communications IC's that can be used to achieve the range mentioned above. At the same time i would like have some useful material about RF communication for long distances.

Please suggest the details required,

regards,
chandu

This Super-Regeneration Transmitter Module (TX434A) is US$4.74 from Oatley Electronics

It can transmit upto 1.5Km's!

You can grab the Receiver for the above device for US$9.47

Thanks for the reply

My application is I have to send 6 sensors data from field to control station by using RF communication. The distance between field and control station is 1.5 km to 2 Km.
(iam sorry, in the last post I have mention 700 meters)
How to make communication between field and control station with out data loss.

Please suggest Hardware details required for this project.

Regards

Without data loss? It's RF there is no way to garuntee data transmission. Even the best bi directional protocols are still prone to interference and periodic outages. If you need a high degree of reliability find out what commercial products are out there.
