transmitreceive

Transmitreceive, often written as transceive, refers to the capability of a device, subsystem, or interface to perform both transmission and reception of signals. The term is used across radio engineering, telecommunications, and certain software and hardware APIs to describe operations that involve sending data or modulated energy and, in the same context, receiving a response or incoming signal.

In hardware, a transceiver typically shares a single physical channel or antenna between TX and RX paths. Switches, duplexers, or time-division schemes separate or switch the paths to avoid self-interference. In half-duplex systems, transmit and receive occur on the same channel but not simultaneously; in full-duplex systems, either separate channels or advanced cancellation techniques allow simultaneous TX and RX.

In software and protocols, a transceive operation is an atomic or semi-atomic action that sends a request and awaits a reply. Examples include NFC transceive commands, radio firmware interfaces, and some network driver APIs that provide a combined transmit-and-receive call. In these contexts, timing, synchronization, and error handling are essential to ensure the transmitted data can be properly received and interpreted.

Related concepts include transceiver, duplex, time-division duplex, frequency-division duplex, half-duplex, and full-duplex. The term broadly covers both hardware implementations and software interfaces designed to support two-way communication through a single pathway or coordinated coordination between transmit and receive operations.
