Before the digital era, and consequently before echo cancellation, full duplex was impossible for a speaker phone simply because it would have caused feedback. The incoming “speaker sound”, along with the effects of the room, could not be eliminated before the microphone transmitted.

Conversations at distance with full duplex, are now possible thanks to good digital technology and echo cancelling.

This is why full duplex is the aim for all telecommunication and also during teleconferences. Long distance conversations with full duplex, are now possible thanks to good digital technology and echo cancelling. A fact that has given us the capability to interrupt one another…
