Configuring 802.11g protection mode
802.11g protection modes include RTS/CTS and CTS-to-self.
• RTS/CTS—An AP sends an RTS packet before sending data to a client. After receiving the RTS
packet, all the devices within the coverage of the AP do not send data within the specified time.
Upon receiving the RTS packet, the client sends a CTS packet. This ensures that all the devices within
the coverage of the client do not send data within the specified time.
• CTS-to-Self—An AP uses its IP address to send a CTS packet before it sends data to a client. This
ensures that all the devices within the coverage of the AP do not send data within the specified time.
