hi friends,
is it possible to transmit video signal from one place to another through mobile communication. if so how can i transmit that? actually i want to transmit video signals from one place to another in wireless manner with encoding. distance between two places is about 10 kms.
For 10km distance and with video compression (encoding) may be this system will be of your interest:
"DIGITAL VIDEO SYSTEM RFI DV20ED REAL TIME VIDEO TRANSMISSION / RECEPTION" **broken link removed**
The 2.4GHz circuits are not as simple as standard VHF/UHF AM transmitters ..
Here you can check out some examples (schematics included): http://www.qsl.net/n9zia/atv/index.html
For that reason I would suggest that you go for off-the-shelf modules which may still require some soldering but all the "hard work" has been done for you ..
Here are the links: **broken link removed**

If you mean from direct from one mobile station to another eg from one car to another car or one person carrying
some equipment to another person then it's possible but only over a few hundred meters in most circumstances
The distance will be limited by obstructions such as buildings and the fresnel effect because both
ends of the link are close to the ground. There are expensive options to relay the signal such
as a satellite link or using a 3G mobile telephone network.

You need the mid point of the path to be at least 18m above the ground. It will only work if one end of the link is on a hill or a tall tower. Using license-exempt 2.4GHz frequencys in a city
will not work because of all the wifi networks and other equipment on 2.4GHZ.
Stand where you want to put one of the antenna's. If you can't see the other end with a pair of binoculars then it probably won't work.
If you want to use 2.4GHz you need to look at the rules in your country. 3watt transmitters or high
gain antennas are not license exempt in most countrys.
