HI,

Well I am facing a problem related RF chips, I need a transmitter and receiver which could work at 315Mhz. Where they should be able to transfer data (with failsafe condition) to each other of about 5Kb by max of 2 sec. Now there is a relative motion of around 350 Km / hr whichy could restrict the data transfer.

Plz provide a solution, or your views plz

Secondly is it possible or not. thirdly plz could some one provide me a document stating the effect of speed on RF tramsmittion........

Plz help..

With Regards
Tarun
 

RF chip Problem

350km/h will add a freq shift to your system, then your center freq is not 315MHz any longer.

If it is a system with 5kb/2sec=2.5kb/s, no problem, it is easy.

But considering the speed of 350km/h, how about the distance between your transmitter and receiver? That will be a problem if the distance is too long.

speed on RF transmission? pls read some wireless communication textbook as a start.
