Aruba AP-120-MNT Data Sheet

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 3x3 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.
