General Hints and Tips
This section provides some useful tips that will optimize the reliability and
performance of your Wireless Arrays.
 The Wireless Array requires careful handling. For best performance, units
should be mounted in a dust-free and temperature-controlled
environment.
 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.
 Keep the Wireless 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).
 If you are deploying multiple units, the Array should be oriented so that
the monitor abgn2 radio is oriented in the direction of the least required
coverage, because when in monitor mode the radio does not function as
an AP servicing stations.
