A transmitter is a device used to send signals.

A transmitter is a device used to send signals, typically in the form of radio waves, to a receiver. It is commonly used in communication systems such as walkie-talkies, wireless microphones, and remote service buttons. In customer service or hospitality settings, transmitters allow staff to respond quickly to calls. When the call button is pressed, the transmitter sends a signal to notify staff or trigger an alert system. Compact and efficient, these devices help improve response time, enhance coordination, and streamline operations. Transmitters are essential tools for wireless communication, ensuring instant connectivity between users across short or long distances.
