Unidentified Known RF Absorbers/Reflectors/Interference Sources
Identifying known RF absorbers, reflectors, and interference sources while in the field during the
installation phase is critical. Make sure that these sources are taken into consideration when you attach
an AP to its fixed location.
RF absorbers include:
Cement/concrete: Old concrete has high levels of water dissipation, which dries out the concrete,
allowing for potential RF propagation. New concrete has high levels of water concentration within
the concrete, blocking RF signals.
Natural Items: Fish tanks, water fountains, ponds, and trees
Brick
RF reflectors include:
Metal Objects: Metal pans between floors, rebar, fire doors, air conditioning/heating ducts, mesh
windows, blinds, chain link fences (depending on aperture size), refrigerators, racks, shelves, and
filing cabinets
Do not place an AP between two air conditioning/heating ducts. Make sure that APs are placed
below ducts to avoid RF disturbances.
RF interference sources include:
Microwave ovens and other 2.4 or 5 GHz objects (such as cordless phones)
Lunch rooms and call centers with cordless headsets
Installing the AP
N O T E
Using the Integrated Wall-Mounting Slots
The keyhole-shaped slots on the back of the AP can be used to attach the device upright to an indoor
wall or shelf. When you choose the mounting location, allow additional space at the right of the unit for
cables.
N O T E
1. At the mounting location, install two screw on the wall or shelf, 1 7/8 inches (4.7 cm) apart. If you
are attaching the device to drywall, Alcatel-Lucent recommends using appropriate wall anchors (not
included).
2. Align the mounting slots on the rear of the AP over the screws and slide the unit into place (see

Service to all Alcatel-Lucent products should be performed by trained service personnel only.
For product dimensions, see
space at the right side of the installed unit for cables, and make sure enough space is available for
antenna articulation.
