Installation guide

Unlike the AP 3500, the newer AP 3600 supports 3SS with twice as many transmitters (4 per band). This
enables faster data rates of up to 450 Mbps. Note that there is an extra radio for redundancy and enhanced
performance (upstream and downstream). Also, the AP 3600 can beamform to 3SS clients as well. The AP
2600 is similar. However, the extra or redundant radio is for upstream because it is a receive only. Therefore,
it is unable to beamform to 3−ss clients but can beamform at the other non−3ss rates.
Using a dual−band design the AP 3600 has a total of 8 transceivers (transmitter/receivers) that use only four
antennas (Figure 31). Four radios are used in each band, 2.4 GHz and 5 GHz.

The AP 2600 is similar to the AP 3600, but has a slight difference as it is a 3x4:3 meaning. The AP 2600 also
has four antennas to help on the receive (upstream signal), but it only uses three transmitters on the
downstream side.
