Which mode indicates that a transceiver is actively transmitting data?

The mode that indicates a transceiver is actively transmitting data is the transmit mode. In this mode, the transceiver engages its components to send data over the communication channel, allowing for real-time data transfer to other connected devices. The transmission can encompass various data types, including control signals, status updates, or payload information essential for the operation of the networked system.

In contrast, the receive mode is dedicated to capturing incoming data, while the idle mode signifies that the transceiver is powered on but not actively engaging in any data operation. The sleep mode indicates that the device is in a low-power state, conserving energy and not participating in active communication. Thus, when discussing the operation of a transceiver, transmit mode is uniquely defined as the status during which data is being sent.
