What is the purpose of an rts signal in wireless networking?

An RTS (Request to Send) signal in wireless networking is used to manage access to the shared communication medium and reduce collisions. When a device wants to transmit data, it first sends an RTS frame to the intended recipient, which reserves the channel for the upcoming data transmission. The recipient then responds with a CTS (Clear to Send) signal, allowing the sender to transmit without interference from other devices. This mechanism is particularly useful in environments with multiple users and can enhance overall network efficiency.
