power per chain (50 mW, combined 3-stream output power) and has a receive sensitivity
of -74 dBm (for 20 MHz) and -72 dBm (for 40 MHz).
In the ceiling mount position, the WLA532 access point contains one vertically polarized
and two horizontally polarized single band 5-GHz antennas with 5-degree down tilt on
the antenna patterns with respect to the vertical axis and an omnidirectional pattern
with respect to the horizontal axis. These polarity diversity antennas maximize the MIMO
performance for the access point mounting positions.

Point
The WLA532 access point has six internal, multiple input multiple output (MIMO)
antennas, with three antennas for each of the access point's two radios. The antennas
support spacial, polarity, and pattern diversity as well as cross-chain and cross-band
isolations for maximum performance. The antennas provide a maximum gain of 3-dBi
at 2.4-GHz throughput and 5-dBi at 5-GHz throughput.
This topic provides graphical depictions of radiation patterns for the internal antennas.
The graphics display relative field strengths of signals transmitted from or received by
the antennas. You can use this radiation pattern information to determine the distance
between access point and client and also where to place the access points.
Figure 3 on page 26 shows the locations of the six antennas. The antennas are numbered
from 1 through 6.

Figure 4 on page 27 shows the horizontal-plane radiation pattern for the access point.
The pattern provides 360-degree even coverage.
