6 Aruba AP-130 Series Access Point | Installation Guide
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
