Aruba 277 Instant Access Point

Aruba 270 Series Access Point

Innovative and aesthetically-designed, our 270-series outdoor APs deliver fast and reliable 802.11ac Wi-Fi performance under any weather conditions.

The three-stream 270 series also enables 802.11n mobile devices to operate up to three-times faster at the same distance from the AP.

Purpose-built for the harshest outdoor environments, 270-series APs can withstand extreme temperatures, persistent moisture and precipitation, and are fully sealed to keep out airborne contaminants.

Wireless Radio Specifications

AP type: Outdoor, dual radio, 5-GHz 802.11ac and 2.4-GHz 802.11n

In addition to 802.11n data rates, the 2.4-GHz radio supports 802.11ac data rates using 256-QAM modulation. This gives TurboQAM-enabled clients a 33% boost above the maximum supported data rate to deliver up to 600 Mbps.
