Cisco Aironet Series Access Points
The AP 2600 is a 3X4:3SS, so ClientLink does not beamform to 3SS clients; however, it does beamform
at legacy, one, and two spatial stream rates. The AP 3600 is a 4X4:3SS, supporting an extra transmitter
chain for additional downlink performance for all bands and clients. The AP 3600 has slightly higher
performance and beamforms to legacy, one, two, and three spatial stream rates and .11ac rates when
using the optional .11ac module.
The two series use the same mounting hardware and antennas. See Figure 10 for a back view.

Because of these similarities, there is no need to repeat a site survey for the AP 2600 if a survey exists
for the AP 3600.
