Requirements; Access Point Placement - Symbol AP-51 Series Product Reference Manual

2.3 Requirements

The minimum installation requirements for a single-cell, peer-to-peer network (regardless of access
point model)
• An AP-5131 or AP-5181 model access point (either a dual or single radio model)
• 48 Volt Power Supply (Part No. 50-24000-050) or Symbol power injector
(Part No. AP-PSBIAS-1P2-AFR)
• a power outlet
• Dual-Band Antennae
NOTE An AP-5131 or AP-5181 model access point optimally uses 2 antennae for

2.4 Access Point Placement

For optimal performance, install the access point (regardless of model) 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 open areas 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 antennae vertically for best reception.
• Point the access point antenna(s) downward if attaching to the ceiling.
Symbol recommends conducting a site survey to define and document radio interference obstacles
before installing the access point to maximize its radio coverage area.
