Wi-Fi antennas

• AP-504:
  • Two (female) RP-SMA connectors for external dual band antennas (A0 and A1, corresponding with radio chains 0 and 1). Worst-case internal loss between radio interface and external antenna connectors (due to diplexing circuitry): 0.7dB in 2.4GHz and 1.3dB in 5GHz.
• AP-505:
  • Two integrated dual-band downtilt omni-directional antennas for 2x2 MIMO with peak antenna gain of 4.9dBi in 2.4GHz and 5.7dBi in 5GHz. Built-in 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 each of the antennas of the MIMO radios, the peak gain of the combined, average pattern is 4.3dBi in 2.4GHz and 5.6dBi in 5GHz.

Power sources and power consumption

• The AP supports direct DC power and Power over Ethernet
  • The AP supports direct DC power and Power over Ethernet
  • When both DC and PoE power sources are available, DC power takes priority over PoE units
  • Power sources are sold separately; see the 500 Series Ordering Guide for details
  • When powered by DC or 802.3at (class 4) PoE, the AP will operate without restrictions units
  • When powered by 802.3af (class 3) PoE and with the IPM feature disabled, the AP will disable the USB port. 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.
• Maximum (worst-case) power consumption (without / with a USB device attached):
  • DC powered: 8.9W / 14.2W
  • PoE powered (802.3at): 11.0W / 16.5W
  • PoE powered (802.3af): 11.0W / 13.5W
  • This assumes that up to 5W is supplied to the attached USB device
• Maximum (worst-case) power consumption in idle mode: 4.3W (DC) or 6.1W (PoE)
• Maximum (worst-case) power consumption in deep-sleep mode: 1.7W (DC) or 3.3W (PoE)
