I am working on making a low latency rf link that will be used as part of a feedback loop on a remote sensor. Because it is real-time the delay needs to be as small as possible (if sub milliseconds are possible I'd leap at it).
Due to the information being transmitted, it only needs to transmit 8 bits at most. In fact if there were an analog rf link (2 frequencies determine the states) that would be suitable for my needs if there was a ready to buy ic.
After reading the questions here and here, then doing my own research, I think there are still better solutions such as found in zigbee.
My question is what is the lowest latency one way rf link?
EDIT: I'm looking for a complete system such as zigbee, wifi, or some other way to incorporate information, with a preference for the lowest latency
