Hello /diy/.

I want to settle a communication using RF. Thing is that the transmitters will have to be movable and the receiver must be static. It will have to work + 100 meters. The transmitter will have to be like a market RFID sticker.

The receiver can have current input, wifi internet, sim paid access.
What electronics do you recommend.

The information from the receiver should be send to the server.
