Radio (2.4G)

You can select or clear channels from which to choose during the automatic channel selection process or select a specific channel on which to operate, or enable Call Admission Control or Spectralink Compatibility for this radio.

Additionally, you can disable WLAN service for this radio entirely by selecting the Enable 2.4 GHz band checkbox and enabling the Overide Group Config toggle switch to on.

Navigating to the Radio (2.4G) tab for the System Default AP Group allows you to view and manage the following information:

Enable 2.4 GHz band Allows you to enable or disable 2.4 GHz radio settings on the third radio in these APs (default is Enabled).
Channelization Allows selection of channel width for the 2.4 GHz radios (Auto, 20, or 40). Default setting is Auto (which is 20 MHz).
Radio 2.4 GHz Allows selection of the spectrum-specific channels from which to choose during the automatic channel selection process.
Channel Allows you to select a specific channel on which to operate. (Auto allows the system to choose the best available channel).
TX Power Allows you to manually set the transmit power on all 2.4 GHz radios.
  • Auto: Default setting that dynamically adjusts the transmit power of an AP based on real-time conditions
  • Full: Maximum allowable transmit power according to country regulations
  • Min: Minimum allowable transmit power according to country regulations
Call Admission Control Allows you to enable or disable Wi-Fi Multimedia Admission Control (WMM-AC) to support Polycom/Spectralink Voice Interoperability for Enterprise Wireless (VIEW) certification (disabled by default).
Protection Mode Protection Mode allows control over how 802.11 devices communicate with another device. Using RTS/CTS (Request to Send/Clear to Send) reduces collisions and increases network performance if hidden stations are present. However, RTS/CTS (and CTS-only) introduce overhead and may reduce the overall performance in some situations. By the proper use of RTS/CTS and CTS-only, you can fine-tune the operation of your wireless LAN depending on the physical operating environment.
  • CTS-only: Choose this option to force all destination devices to acknowledge their ability to receive data when a transmission is initiated. Use this option for compliance with the Wi-Fi Alliance certification.
  • RTS/CTS: Choose this option to force both sending and receiving devices to confirm a data exchange on both ends before proceeding.
  • None: Choose this option to disable both RTS and CTS acknowledgment.
