Innovative and aesthetically-designed 270 series outdoor wireless access points deliver gigabit Wi-Fi performance to 802.11ac mobile devices under any weather conditions. The 270 series is also the only outdoor AP that enables 802.11n clients to operate three-times faster at greater distances.

Purpose-built to survive in the harshest outdoor environments, 270 series APs withstand exposure to extreme high and low temperatures, persistent moisture and precipitation, and are fully sealed to keep out airborne contaminants. All electrical interfaces include industrial strength surge protection.

With a maximum data rate of 1.3 Gbps in the 5-GHz band and 600 Mbps in the 2.4-GHz band, 270 series outdoor APs supports concurrent dual-radio operation at speeds that greatly exceed Fast Ethernet.

Wi-Fi Client Optimization

To eliminate sticky client behavior and ensure consistently high performance, every Aruba AP includes ClientMatch™ technology, which gathers session performance metrics that steer mobile devices to the best AP and radio on the WLAN in real time.


  • Innovative industrial design
    • Eliminates installation complexity
    • Inconspicuous design that improves aesthetics
    • Delivers IP66 - and IP67-rated protection from the elements
  • Best-in-class RF management
    • EtherChannel link aggregation on two Gigabit Ethernet ports provides 1.9 Gbps throughput.
  • 600 Mbps in the 2.4-GHz band.
    • Supports up to 600 Mbps for TurboQAM-enabled mobile devices operating in the 2.4-GHz band – an industry first
  • Best-in-class RF management
    • Integrated Adaptive Radio Management™ technology manages the 2.4-GHz and 5-GHz radio bands and ensures that APs stay clear of RF interference
  • Reliable and predictable Wi-Fi performance
    • Patented ClientMatch™ technology ensures that roaming clients associate with the best AP to maximize performance
    • AppRF™ technology identifies and prioritizes applications on the network
  • Spectrum analysis
    • Capable of part-time or dedicated spectrum analysis, which scans the 2.4-GHz and 5-GHz radio bands to identify sources of RF interference
  • Limited lifetime warranty – an industry first for outdoors


The 270 series of outdoor APs offers a choice of operating modes to meet your unique management and deployment requirements.

  • Controller-managed AP or Remote AP (RAP) running ArubaOS™. When managed by Aruba Mobility Controllers, the 270 series offers centralized configuration, data encryption, policy enforcement and network services, as well as distributed and centralized traffic forwarding.
  • Aruba Instant™ AP running InstantOS™. In Aruba Instant mode, one AP automatically distributes the network configuration to other APs. Just power-up one Instant AP, configure it over the air, and plug in the other APs – the entire process takes about five minutes.
  • In addition to operation mode, the APs can be optionally configured to perform the following functions:
    • Spectrum analysis: Dedicated scan mode identifies sources of RF interference.
    • Air monitoring: Dedicated scan mode provides wireless intrusion protection.
    • Hybrid AP: Serves Wi-Fi clients and simultaneously provides wireless intrusion protection and spectrum analysis.

    For large installations with multiple sites, the Aruba Activate™ service reduces deployment time by automating provisioning, firmware upgrades, and inventory management. With Aruba Activate, Instant APs are factory shipped to any site and configure themselves when powered up.

    If WLAN and network requirements change, a built-in migration path allows 270 series Instant APs to become part of a WLAN that is centrally managed by a Mobility Controller.
