• Available channels: Dependent on configured regulatory domain.
• Dynamic frequency selection (DFS) optimizes the use of available RF spectrum.
• Supported radio technologies:
  • 802.11b: Direct-sequence spread-spectrum (DSSS)

Antennas

• Eight integrated downtilt omni-directional antennas for 4x4 MIMO with maximum antenna gain of 4.0 dBi in 2.4 GHz and 4.7 dBi in 5 GHz. Built-in antennas are optimized for horizontal ceiling-mounted orientation of the AP. The downtilt angle for maximum gain is ~ 30 degrees. Combining the patterns of each of the antennas of the MIMO radios, the peak gain of the effective per-antenna pattern is 2.7dBi in 2.4GHz and 2.9dBi in 5GHz.
