Wall Mounting the AP
When the AP needs to be wall-mounted, the installer should understand that walls can be a physical obstacle to the wireless signal.
Therefore, maintaining 360 degree coverage may be compromised by the wall. If the wall is an outside wall and/or the goal is to send
the signal in an 180-degree pattern instead, a directional antenna, often referred to as a
“ patch ” antenna, may be a better choice
assuming that the AP 1850e is used.
Avoid wall-mounting APs with internal antennas, such as the AP 1850i, unless you use the optional Oberon right-angle mount ( Figure
9: Wall-Mounting APs Antennas Should be Vertical (Up/Down) or Use the Oberon Right-Angle Mounting Structure - Ideal for the
“ I ” series such as 1850i, 2700i, 3600i or 3700i Oberon P/N 1029-00), on page 11 ). The internal antenna model is designed to mount
to a ceiling to provide 360-degree coverage. If wall-mounted in a non-ceiling orientation, the signal may penetrate the floor above
and below causing unintended coverage. This results in additional and needless roaming access when a mobility client, for example
a user with Wi-Fi phone, walks by on an adjacent floor.
Instead, use the AP 1850e (with dipoles or patch antennas) or use an optional wall mount that puts the AP 1850i or AP 1850e into a
ceiling type orientation when mounted to a wall.
APs with internal antennas such as the AP 1850i that are wall mounted should use the Oberon mounting
bracket unless roaming is not an issue, for example, hotspot, kiosk, or small venue scenario.

such as 1850i, 2700i, 3600i or 3700i Oberon P/N 1029-00)
Oberon model 1029-00 is a right angle mount works with
“
i
”
and
“
e
”
models to put the AP in the right antenna orientation. If the unit
is an “ e ” model with dipoles that can be mounted (far right), then an Oberon wedge mount is not required.
