These comes from: http://www.kjell.com

Where can i buy similar products, but with a stronger output. I want to be able to send data up to 1-2 km. These ones only manages 200 meters in open field.

 

These low power ones are licence free, for higher power ones you will need a licence - this is likely to be difficult and expensive to obtain - if you can obtain one at all. I don't know what country you are from, but in the UK using an unlicenced transmitter is a serious offence, with suitably serious maximum punishments - including unlimited fines and jail terms.

 

Where did you find the fisrt low power ones?
I want to take a look closer to it.
