Identifying 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 access point 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 in 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 access point between two air conditioning/heating ducts. Make sure that access points 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)
Cordless headset such as those used in call centers or lunch rooms
!
Portable RF communications equipment (including peripherals such as antenna cables and external antennas)
should be used no closer than 30 cm (12 inches) to any part of the access point. Otherwise, degradation of the
performance of this equipment could result.
RF Radiation Exposure Statement: This equipment complies with RF radiation exposure limits. This equipment
should be installed and operated with a minimum distance of 13.78 inches (35cm) between the radiator and
your body for 2.4 GHz and 5 GHz operations. This transmitter must not be co-located or operating in conjunction
with any other antenna or transmitter.
