Hello Experts,
Off late, I could not find any 4 spatial stream capable Access Points in Cisco. Has been going through the datasheets of flagship models in Outdoors (1572EAC) and Indoor (3800E). These are 4 Rx & 4 Tx but with 3 spatial streams.
What is the 4th Tx Rx Antenna in 4*4 is used for in these AP models as its not been for facilitating the 4th spatial stream?

Not from the classical AP-line, but at least from Cisco and 4-stream: https://meraki.cisco.com/products/wireless/mr53

Thanks Karsten,
I am wondering what the fourth Tx Rx Antenna on 1572AP facilitates for?

To my understanding (hopefully the Wireless Pros will correct or add to that), it's used for beamforming as it needs one more antenna then spatial streams.
