My requirement is to transmit a binary form of data from one Road Junction to another road junction which is around 4 to 5 km away.
I am going to get the traffic information from each road in the form of binary (4 bits) and transmit this data to the connected junctions of my current traffic measured junction.
So I want to transmit a binary form (For ex: 1010) to that junction.
In the other junctions I have a Receiver which receives this binary form of data and manipulates this. So for this requirement which Transmitter and Receiver is good? I have an option to use FM transmitter and FM receiver based on my past experience. But I want to explore things and find Transmitter and Receiver other than FM transmitter and Receiver.
I hope you got it right. I don't know If I am overlooking anything here.
