2.3    Access Point Placement
For optimal performance, install the access point away from transformers, heavy-duty motors, 
fluorescent lights, microwave ovens, refrigerators and other industrial equipment. Signal loss can 
occur when metal, concrete, walls or floors block transmission. Install the access point in an open 
area or add access points as needed to improve coverage.
Antenna coverage is analogous to lighting. Users might find an area lit from far away to be not bright 
enough. An area lit sharply might minimize coverage and create dark areas. Uniform antenna 
placement in an area (like even placement of a light bulb) provides even, efficient coverage.
Place the access point using the following guidelines:
• Install the access point at an ideal height of 10 feet from the ground.
• Orient the access point antennas vertically for best reception.
• Point the access point antennas downward if attaching to the ceiling (external antenna 
models only). 
To maximize the access point’s radio coverage area, Motorola Solutions recommends conducting a 
site survey to define and document radio interference obstacles before installing the access point.
2.3.1    Antenna Options
Motorola Solutions supports two antenna suites for the single radio, dual-band AP-6521 Series 
access point. One antenna suite supporting the 2.4 GHz band, and another antenna suite supporting 
the 5 GHz band. Select an antenna best suited to the intended operational environment of your access 
point.
