Datasheet

Wireless radio specications
• AP type: Indoor, dual radio, 5GHz 802.11ac and 2.4GHz
802.11n
- In addition to 802.11n data rates, the 2.4GHz radio
supports 802.11ac data rates using 256-QAM
modulation. This gives TurboQAM-enabled clients a
33% boost above the maximum supported data rate.

• Transmit power: congurable in increments of 0.5dBm
• Maximum (aggregate, conducted total) transmit power
(limited by local regulatory requirements):
- 2.4GHz band: +23dBm (18 dBm per chain)
- 5GHz bands: +23dBm (18 dBm per chain)
• Advanced Cellular Coexistence feature to eectively deal
with interference from cellular systems
• Maximum ratio combining for improved receiver
performance
• Cyclic delay diversity for improved downlink RF performance
• Short guard interval for 20, 40 or 80MHz channels
• Space time-blocking code for increased range and improved
reception
• Low-density parity check for high-eciency error correction
and increased throughput
• Transmit beam-forming for increased reliability in signal
delivery
• Supported data rates (Mbps):
- 802.11b: 1, 2, 5.5, 11
- 802.11a/g: 6, 9, 12, 18, 24, 36, 48, 54
- 802.11n: 6.5 to 450 (MCS0 to MCS15)
- 802.11ac: 6.5 to 1,300 (MCS0 to MCS9, NSS = 1 to 3)
• 802.11n high-throughput (HT) support: HT 20/40
• 802.11ac very high throughput (VHT) support: VHT 20/40/80
• 802.11n/ac packet aggregation: A-MPDU, A-MSDU
Power
• Maximum power consumption: 15W, plus up to 2.5W for
attached USB device.
• Power sources sold separately
• Direct DC source: 12V DC nominal, +/- 5%
• Power over Ethernet (PoE): 48V DC (nominal) 802.3af or
802.3at-compliant source
- Efficient Mode PoE: Power savings with 802.3af POE
and limited functionality:
> USB port disabled
> Second Ethernet port disabled
> 2.4GHz 802.11n radio in 1x3:1 spatial-stream mode
> 5GHz 802.11ac radio operates without restrictions*
- Unrestricted functionality with 802.3at POE+
*With ArubaOS software 6.3.0, the 5GHz 802.11ac radio operates
in 2x3:2 spatial stream mode when the AP is powered by 802.3af
PoE. This restriction has been removed in 6.3.1.
Antennas
• AP-224: Three RP-SMA connectors for external dual-band
antennas. Internal loss between radio interface and external
antenna connectors (due to diplexing circuitry): 1.5dB in
2.4GHz and 3.0dB in 5GHz.
• AP-225: Six integrated down-tilt omni-directional antennas
for 3x3 MIMO with maximum antenna gain of 3.5dBi in
2.4GHz and 4.5dBi in 5GHz. Built-in antennas are optimized
for horizontal ceiling mounted orientation of AP-225
Other interfaces
• Two 10/100/1000Base-T Ethernet network interfaces (RJ-
45):
- Auto-sensing link speed and MDI/MDX
- Load balancing support to achieve platform throughput
greater than 1Gbps
