Installation guide

The AP 3600e (external antenna version) differs in appearance from the AP 3500e, having fewer antenna
connector ports primarily due to the dual−band antenna systemthat is used.
The AP 3500e has separate antennas for each band, 2.4 GHz and 5 GHz, and does not support 3SS technology
because it has only two transceivers and one receiver per band (2SS).
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 are not combined, 8 antennas are required. The AP 3600 has
four transceiver (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. This improves the
overall performance of all 802.11n clients with 1, 2 and 3 spatial streams.
Note: Beamforming to a 3SS client requires n+1 RF design. In order to accomplish this, the AP 3600 has an
additional radio per band, which improves client performance by using Cisco ClientLink 2.0.
The newer AP 3600 design supports an additional feature module. The bottom of the AP 3600 unit looks
different as it has openings to support the feature module. The openings, while fully sealed, permit the module
to have access to the topside of the AP to allow the module antennas (if present in the module being used) to
fully function. The unit includes a positive snap spring loaded BB so the installer can feel a positive lock
when the AP is fully engaged in the bracket (see figure 5).
AP 3600 Feature Module Support
The feature module adds new functionalty to the AP to future−proof customers' investment. The first available
module provides a dedicated monitor module to scan the full spectrum (not just the channel on which the AP
