ARUBA 270 SERIES
OUTDOOR ACCESS POINTS
Setting a higher standard for 802.11ac
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.
UNIQUE BENEFITS
• 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
- 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 identies 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 rst for outdoors
CHOOSE YOUR OPERATING MODE
The 270 series of outdoor APs oers 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 oers centralized conguration, data
encryption, policy enforcement and network services, as
well as distributed and centralized trac forwarding.
• Aruba Instant AP running InstantOS. In Aruba Instant
mode, one AP automatically distributes the network
conguration to other APs. Just power-up one Instant AP,
congure it over the air, and plug in the other APs – the
entire process takes about ve minutes.
• Secure enterprise mesh

ARUBA 270 SERIES OUTDOOR ACCESS POINTS
In addition to operation mode, the APs can be optionally
congured to perform the following functions:
• Spectrum analysis: Dedicated scan mode identies
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,
rmware upgrades, and inventory management. With Aruba
Activate, Instant APs are factor y shipped to any site and
congure 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.
