Aruba AP-120 and AP-121 Access Points

This product has been retired. Please contact sales to discuss replacement products.

The 120 and 121 802.11n indoor access points are designed for maximum deployment flexibility in low-density environments that require above-ceiling or enclosure-based installations.

The multifunction AP-120 and AP-121 are indoor 802.11n access points (APs) designed for maximum deployment flexibility in low-density environments that require above-ceiling or enclosure-based installations. These high-speed APs deliver wire-like performance at date rates up to 300 Mbps.

The AP-120 features a single 3×3 MIMO dual-band 2.4-GHz/5GHz radio with detachable antenna interfaces while the AP-121 features the same radio with integrated antenna elements. Both APs are built to provide years of trouble-free operation and are backed by a limited lifetime warranty.

Working with Aruba’s line of centralized Mobility Controllers, the AP-120 and AP-121 deliver secure, high-speed network services that move users to a “wireless where possible, wired where necessary” network access model. The network can then be rightsized by eliminating unused Ethernet switch ports and thereby reducing operating costs.

802.11n enables the use of wireless as a primary connection with speed and reliability comparable to a wired LAN. It also increases performance by utilizing techniques such as channel bonding, block acknowledgement and MIMO radios. Advanced antenna technology also increases range and reliability.

The key to ensuring wire-like performance and reliability is Aruba’s unique Adaptive Radio Management and spectrum analysis* capabilities, which manage the 2.4-GHz and 5-GHz radio bands to deliver maximum client performance while mitigating any RF interference.

The multifunction AP-120 and AP-121 can be configured through the Mobility Controller to provide WLAN access with part-time air monitoring, dedicated air monitoring for wireless IPS and spectrum analysis, Remote AP (RAP) functionality or secure enterprise mesh. The AP-120 and AP-121 feature dual 100/1000BASE-T Ethernet interfaces and operate from standard 802.3af power-over-Ethernet (PoE) sources.
