Cisco Aironet 1600/2600/3600 Series Access Point Deployment Guide
Cisco Aironet Series Access Points
From a side view, the AP 3600i is slightly thicker (2.11”) than the AP 3500 (1.84”), as shown in
.
The thicker size allows for additional radio support and printed circuit board area, as well as feature
modules for future capabilities. While the AP 3600i has a little more depth, it is completely backward
compatible with the mounting brackets for the existing Cisco Aironet 1040 Series Access Point (AP
1040), 1140 Series Access Point (AP 1140), 1260 Series Access Point (AP 1260), and the AP 3500.

Side View of the AP 3600i and the AP 3500
The external antenna models (the AP 3600e and the AP 3500e) differ in appearance because the AP
3600e has fewer antenna connector ports, primarily due to the dual-band antenna system.
3600e has fewer antenna connector ports, primarily due to the dual-band antenna system.
The AP 3600e has combined all the antenna ports (dual-band) so that each antenna port can transmit
simultaneously on each band; if the antenna ports were not combined, this would have required eight
antennas. The AP 3600 has four transceivers (transmitter/receiver) radio ports per band for a total of
eight transceivers, four in each band. This additional radio per band permits beamforming to 3SS clients
using ClientLink 2.0 to improve the overall performance of all 802.11n clients with one, two, and three
spatial streams.

Note
Beamforming to a 3SS client requires n+1 radio frequency (RF) design. To accomplish this, the AP 3600

The AP 3500e has separate antennas for each band, 2.4 GHz and 5 GHz, and does not support 3SS
technology, since it has only two transceivers (transmitter/receiver) and one extra receiver per band
enabling operation up to two spatial streams.

Unlike the AP 3500, the newer AP 3600 design supports an optional, add-on feature module. The bottom
of the AP 3600 has openings to support the feature module, as shown in

feel a positive lock when the AP is fully engaged in the bracket.
