General Hints and Tips
This section provides some useful tips that will optimize the reliability and
performance of your Wi-Fi Arrays.
z
The Wi-Fi Array requires careful handling. For best performance, units
should be mounted in a dust-free and temperature-controlled
environment.
z
If using multiple Arrays in the same area, maintain a distance of at least
100 feet (30m) between Arrays if there is direct line-of-sight between the
units, or at least 50 feet (15 m) if a wall or other barrier exists between the
units.
z
Keep the Wi-Fi Array away from electrical devices or appliances that
generate RF noise. Because the Array is generally mounted on ceilings, be
aware of its position relative to lighting (especially fluorescent lighting).
z
If using AC power, each Wi-Fi Array requires its own dedicated AC
power outlet. Do not attempt to “piggy-back” AC power to multiple
units. To avoid needing to run separate power cables to one or more
Arrays, consider using Power over Gigabit Ethernet.
