I know how to send and receive simple slow code (like on/off signals) using an encoder-decoder combination such as the popular Holtek HT12E/HT12D pair and OOK RF modules like inexpensive 434 MHz Tx-Rx pairs.
I would like to operate four such pairs in close proximity at the same time. Each pair will have its own unique hard-wired address code for identification. The transmitters will be an inch or so apart and the receivers will be some feet from each other.
The scenario is similar to operating simple RC toy cars close together. The difference is that some of these toy cars don't even use ID address codes and will surely interfere with each other if operated close together.
No doubt there are more sophisticated ways of doing what I want to do. But will the scheme outlined above work properly? What is the likelihood of cross interference between the different pairs, either from code collision or from swamping of RF signals?
