Cisco Aironet Series 3700 Access Point

Figure 55

AP 3500i/e is a 2x3:2 System (Supports up to 2 Transmit Chains)

Note

2x3:2 implies two transmitters and three receivers supporting 2 spatial streams.

Figure 56

Modulation and Coding Scheme: 2SS Bonded Channel Supports up to 300 Mbps

Unlike the AP 3500, the newer AP 3600 supports 3SS with twice as many transmitters (4 per band)
enabling faster data rates of up to 450 Mbps. Note that there is an extra radio for redundancy and
enhanced performance (upstream and downstream) and the AP 3600 can also beamform to 3SS clients
as well.

Using a dual-band design, the AP 3600 has a total of 8 transceivers (transmitter/receivers) using only 4
antennas (

Figure 57

). Four radios are used in each band, 2.4 GHz and 5 GHz.
