    I was asked How Come that Cisco released AP3700 ( .11ac  capable  &  4*4 MIMO ) While Aruba AP225 is .11ac capable but  3*3 MIMO ?

    Aruba is Expected to be the faster ???

    Actually  if someone asked me that i would ask him back, how many clients 4x4 ac capable do you see around?

    The 4x4 ac is useless if you dont have any client that is 4x4ac capable.

     

    Aruba i bealive will get in there soon but for now i bealive its not worth it maybe?

     

    Just my 2 cents

     

    Cheers

    Cisco claims that with 4x4:3 they get better coverage with higher speed.  They said to achieve max speed (450 mbps per antenna) you need to be closer to the AP then approx. 4-5 meters (1 m = 3,3 feet) given that the AP is mounted in the ceiling at normal height.  With their 3700 and 4x4:3 the distance increase to 8-10 meters before connection speed drops.  It uses "the extra" antenna to increase the received signal at the client (with beam forming) and the client does not need to be a 4x4:3 client.  It only uses 3 spatial streams, so the client would not know.

     

    Would be nice to have some more input on this from Aruba.
