  • Part Number: IAP-205-US
  • In Stock

  • The IAP-205 model features four integrated omni-directional downtilt antennas, while the AP-204  and IAP-204 support external detachable dual-band antennas using two RP-SMA antenna connectors.
  • Patented ClientMatch™ technology improves performance and eliminates sticky client behavior while roaming.
  • AppRF technology enables prioritization and policy enforcement for business-critical enterprise apps like Microsoft Lync.
  • The 200 series can be managed by an Aruba Mobility Controller or deployed in controllerless Aruba Instant mode.


  AP-205 and IAP-205

2.4-GHz (300 Mbps max rate) and 5-GHz (867 Mbps max rate) radios, each with 2×2 MIMO and four integrated omni-directional downtilt antennas.

   AP-204 and IAP-204

.4-GHz (300 Mbps max rate) and 5-GHz (867 Mbps max rate) radios, each with 2×2 MIMO and two combined, diplexed external RP-SMA antenna connectors.


   RF management

Adaptive Radio Management™ (ARM) technology automatically assigns channel and power

settings, provides airtime fairness and ensures that APs stay clear of all sources of RF interference to deliver reliable, high-performance WLANs.

The 200 Series APs can be configured to provide part-time or dedicated air monitoring for spectrum analysis and wireless intrusion protection, VPN tunnels to extend remote locations to corporate resources, and wireless mesh connections where Ethernet drops are not available.

  Spectrum analysis

Capable of part-time or dedicated air monitoring, the spectrum analyzer remotely scans the 2.4-GHz and 5-GHz radio bands to identify sources of RF interference.


With an OpenDNS service subscription, Aruba Instant APs deliver integrated web filtering, malware and botnet protection to every device connected to the WLAN.

Integrated Trusted Platform Module (TPM) for secure storage of credentials and keys

SecureJack-capable for secure tunneling of wired Ethernet traffic.
