  • 5.470 to 5.725GHz
  • 5.725 to 5.850GHz
• 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)
  • 802.11a/g/n/ac: Orthogonal frequency-division multiplexing (OFDM)

  • 802.11n/ac packet aggregation: A-MPDU, A-MSDU

Wi-Fi Antennas

• AP-303: Internal antenna models.
  • Two vertically polarized dual-band downtilt omnidirectional antennas for 2x2 MIMO with peak antenna gain of 3.5dBi (2.4GHz) and 6.9dBi (5GHz) per antenna.
  • The antennas are optimized for horizontal ceiling mounted orientation of the AP. The downtilt angle for maximum gain is roughly 30 degrees.
  • Combining the patterns of both antennas per radio, the peak gain of the average (effective) pattern is 2.1dBi in 2.4GHz and 5.7dBi in 5GHz.

Mounting

• The AP ships with a (black) mount clips to attach to a 9/16-inch or 15/16-inch flat T-bar drop-tile ceiling
• Several optional mount kits are available to attach the AP to a variety of surfaces; see the Ordering Information section below for details
