dupleksing

Dupleksing is a term primarily used in telecommunications and electronics to describe a technique that allows for bidirectional communication over a single communication channel. This means that signals can be sent and received simultaneously or in rapid alternation without requiring separate, dedicated channels for each direction. The core principle of dupleksing is the efficient use of bandwidth and resources.

There are two main types of dupleksing: half-duplex and full-duplex. In half-duplex communication, devices can transmit and receive, but not at the same time. For example, a walkie-talkie operates in half-duplex mode; one person speaks while the other listens, and then they switch roles. In contrast, full-duplex communication allows for simultaneous transmission and reception. A standard telephone conversation is a prime example of full-duplex; both parties can speak and hear each other concurrently.

The implementation of dupleksing often involves techniques like frequency division duplexing (FDD), where different frequencies are allocated for transmitting and receiving, or time division duplexing (TDD), where the same frequency is used, but transmission and reception occur in alternating time slots. Dupleksing is a fundamental concept enabling much of modern communication, from radio to cellular networks and Ethernet.
