Thanks for answering.

I simply need to send one and only one bit per receiver. Let's say I have one emitter(we will call it X) and 2 receivers (A and B).

I want to activate one first a then the other, in any order.

So X sends a bit to A

Then X sends a bit to B

Then again, one to A

OR

X sends a bit to B

Then X sends a bit to A

Then again, one to B

You say is very possible, with frequency multiplexion?
