In tri-radio mode, the peak gain of the antennas for each of the 4x4 5GHz radios is 5.5dBi (radio 0L, lower half of 5GHz) and 5.6dBi (radio 0U, upper half of 5GHz). Built-in antennas are optimized for horizontal ceiling mounted orientation of the AP. The downtilt angle for maximum gain is roughly 30 degrees.
      • A mix of horizontally and vertically polarized antenna elements is used
      • Combining the patterns of each of the antennas of the MIMO radios, the peak gain of the combined, average pattern is 2.4dBi in 2.4GHz and 0.7dBi in 5GHz (dual- radio mode).
      • In tri-radio mode, the peak gain of the combined, average pattern is 1.1dBi (radio 0L, lower half of 5GHz) and 3.6dBi (radio 0U, upper half of 5GHz)

  • Power sources and power consumption
    • The AP supports direct DC power and Power over Ethernet (POE; on port E0 and/or E1)
    • When POE power is supplied to both Ethernet ports, the AP can be configured to combine or prioritize power sources
    • When both DC and POE power sources are available, DC power takes priority over POE
    • Power sources are sold separately; see the ordering Information section below for details
    • When powered by DC, 802.3bt (class 5) POE or 2x 802.3at (class 4) POE, the AP will operate without restrictions.
    • When powered by 1x 802.3at (class 4) POE and with the IPM feature disabled, the AP will disable the USB port, disable the other Ethernet port, operate the 5GHz radio in 4x4 mode, and disable tri-radio operation
    • In the same configuration but with IPM enabled, the AP will start up in unrestricted mode, but may dynamically apply restrictions depending on the POE budget and actual power. The feature restrictions and order can be programmed.
    • Operating the AP with an 802.3af (class 3 or lower) POE source is not supported.
    • Maximum (worst-case) power consumption (dual-radio operation):
      • DC powered: 32.6W
      • POE powered (802.3bt or dual 802.3at): 38.2W
      • POE powered (802.3at, IPM disabled): 25.1W
      • All numbers above are without an external USB device connected. When sourcing the full 5W power budget to such a device, the incremental (worst-case) power
        consumption for the AP is up to 6.0W (POE powered) or 5.4W (DC powered).
    • Maximum (worst-case) power consumption in idle mode (dual-radio operation): 15.0W (POE) or 15.1W (DC).
    • Maximum (worst-case) power consumption in deep-sleep mode: 3.8W(POE) or 3.6W (DC)
