1572 Antenna Ports
The AP1572EC has four antenna ports with N Type connectors, two on the top of the access point (AP) and two on the bottom of
the AP. When in Dual band mode, all antenna ports are used creating four transmitters and four receivers with three spatial streams
(4x4:3) for both 2.4 GHz and 5 GHz. Antennas that support multiple bands are called Dual Radiating Element (DRE), and they
contain dual radiating element inside the antenna.

When in Single band mode, the bottom antenna ports (port 1 and port 2) are used for 2.4 GHz antennas (2x2:2), and the top ports are
for 5 GHz (2x2:2) (port 3 and port 4). Antennas that support a single band are Single Radiating Elements (SRE), and they contain
single radiating elements inside the antenna. The AP1572IC has internal antennas, which cannot be configured as part of the Antenna
Flexport feature.
