Radios

All wireless APs are equipped with at least two radios — Radio 1 and Radio 2:

• Radio 1 supports a 5 GHz radio band
• Radio 2 supports a 2.4 GHz radio band

The 39xx, 38xx and AP37xx series radios (except AP3705i) support up to 450Mbps using three spatial streams.

The radios are enabled or disabled through the Wireless Assistant. For more information, see Modifying 11n and 11ac Wireless AP Radio Properties.

The Unlicensed National Information Infrastructure (U-NII) bands all lie within the 5 GHz band, designed for short-range, high-speed, wireless networking communication.

802.11n APs support the full range of frequencies available in the 5 GHz band:

• 5150 to 5250 MHz - U-NII Low band
• 5250 to 5350 MHz - U-NII Middle Band
• 5470 to 5700 MHz - U-NII Worldwide
• 5725 to 5825 MHz - U-NII High Band
  

  Note

  802.11n-compliant wireless APs can achieve link rates of up to 300 Mbps. You can configure the controller for this higher level link rate. For more information, see Achieving High Throughput with 11n and 11ac Wireless APs.
