Amped Wireless AP1200EX
High Power AC1200 Pro Wi-Fi Access Point
The supported transmission rates listed in the Test Report NII document at the FCC (1300 Mbps 802.11ac, 450 Mbps 802.11n) suggest that this device supports three spatial streams on the 5GHz radio despite being labeled as AC1200 which typically means two spatial streams. The same document lists two antennas which likely means that this is actually a two-stream device and the listed transmission rates are wrong.
