SynCE leverages data synchronization techniques to achieve full-duplex communication between mobile devices and computers.

This allows for full-duplex (both directions at the same time) communication.

With these, a full-duplex communication is established.

Using different pins allows for full-duplex communication, in which information can travel in both directions at once.

WebSocket is a web technology providing full-duplex communications channels over a single TCP connection.

Like TCP, WebSocket provides for full-duplex communication.

This full-duplex communication is possible because each lane is itself composed of one pair of signals: send and receive.

Indeed, for example, that is the case for echoplex error checking, which requires full-duplex communication, so that received data can be echoed back as they are being received.

The three standards support both full-duplex and half-duplex communication.

Using a modem also allows for frequency-division multiple access to be used, making full-duplex digital communication with many users possible using a single wire.
