RF communication

[chandu13]

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 **broken link removed**
**broken link removed**

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
chandu

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.

How about reading the thread above then ?

ok this isnt a answer just a common sense thing. Even commercial products suffer data loss. The thing is they have checks in place where like if the data if corrupt or the data is missing aka CRC check failed then it will resend the data.

You can create your own checks and determine if data is bad or what ever the case and resend the data. Since this is a microcontroller we are talking about its doing everything so fast it will always seem as if there is no data loss because it will try to fix the problem so many times within a second its not even funny lol

to microcontrollers data are getting transmitted while wired. now am tring to transmit through rf fsk tx 01 inone and rx01 in other to receive. but nothing is happening. when check the input to tx01 through oscilloscope 0&1 is shown, but nothing is happening in the receiver side... how to check it
