These came from A&M university when they upgraded their equipment. They have been tested and are working properly. You will receive 3 Aruba 325 access points like the ones in the listing's pictures.
The320 Series AP-325 Indoor Dual-Radio Wireless Access Pointfromarubaoffers maximum data rates of up to 1,733 Mb/s in the 5 GHz band (802.11ac) and 800 Mb/s in the 2.4 GHz band (802.11n) for an aggregated date rate of 2.5 Gb/s. Each radio supports multi-user MIMO (MU-MIMO) and four spatial Access Point streams (4SS). It provides simultaneous data transmission to multiple devices, maximizing data throughput and improving network efficiency. The unit has eight integrated omnidirectional down-tilt antennas that are optimized for horizontal ceiling mounted orientation of the access point.

This dual-radio access point (AP) includes enhanced ClientMatch technology that extends the client steering technology with MU-MIMO client awareness. It automatically identifies MU-MIMO capable mobile devices and steers those devices to the closest MU-MIMO capable Aruba access point. By grouping MU-MIMO capable mobile devices together, the network starts taking advantage of the simultaneous transmission to these devices, increasing its overall capacity. These dynamic roaming policies that are based on device types, help customers achieve optimum WLAN performance in a mixed device environment during the technology transition period.

The unit features an integrated Bluetooth Aruba Beacon that simplifies the remote management of a network of large scale battery-powered Aruba beacons while also providing advanced location and indoor way finding, and proximity based push notification capabilities. It enables businesses to leverage mobility context to develop applications that will deliver an enhanced user experience and increase the value of the wireless network for organizations.
