Setting Signal Strength Display Units
•
Obstructions – A physical obstruction such as metal shelving or a steel pillar can hinder the
performance of wireless devices. Avoid placing these devices in a location where a metal barrier is
between the sending and receiving antennas.
•
Building materials – Radio penetration is greatly influenced by the building material used in
construction. For example, drywall construction allows greater range than concrete blocks, and
metal or steel construction is a barrier to radio signals.
Note
Refer to the hardware installation guide for your infrastructure device for additional information on
factors affecting placement.
