communications path. On a wall, orient the AP433e horizontally so that you can
read the Meru logo without tilting your head at 90 degrees - this orientation
provides optimum MIMO performance.
Meru recommends planning for about 50 clients per radio (or per interference
region) if you plan to use Virtual Port and plan to have phones as clients. For a
data-only installation, plan up to 128 clients per radio. Refer to the Meru
Deployment Guides on the support site for more information.
AP433e is designed to provide 360 degree omni-directional coverage as illustrated
below. Plan placement with this pattern in mind.
Figure 5, Coverage Pattern for AP433e when Ceiling Mounted
Most installations receive the best coverage using the following guidelines:
Install APs toward the center of the building.
Place APs about 80 feet apart.
Do not install APs near metal objects, such as heating ducts, metal doors, or
electric service panels.
For best coverage, orient antennas as shown in Figure 2 AP433e.

Attach the Provided Antennas
All AP433es have nine external antenna ports, labeled A1 – A9. These units
operate with nine antennas attached, even though some configurations don’t use
all nine. Instead of attaching an antenna, you can cap unused antenna connectors
with 50 ohm Reverse Polarity SMA terminators. (For a list of approved terminators,
see http://support.merunetworks.com/.) Meru-supplied antennas are suitable only
for indoor use. To achieve the best performance from your AP433e, user shall
position antennas at a 90 degree angles relative to each other as shown in Figure
6, AP433e Antennas in Ceiling and Wall-mount Configuration. (The antennas do
not have to be oriented exactly as shown in the figure, but it is important to
maintain the relative angles.) If for some reason you are unable to maintain those
angles, the network will still operate, but you may experience up to a 20% drop in
throughput depending on the antenna orientation.

Do not leave any antenna connectors opened. All connectors on the AP must be
