Wireless Array
Installing the Wireless Array 29
depending on the types of materials and background RF (radio frequency) noise
at your location. To maximize wireless range, follow these basic guidelines:
1. Keep the number of walls and ceilings between the Array and your
receiving devices to a minimum — each wall or ceiling can reduce the
wireless range from between 3 and 90 feet (1 to 30 meters). Position your
devices so that the number of walls or ceilings is minimized.
2. Be aware of the direct line between each device. For example, a wall that
is 1.5 feet thick (half a meter) at 90° is actually almost 3 feet thick (or 1
meter) when viewed at a 45° angle. At an acute 2° degree angle the same
wall is over 42 feet (or 14 meters) thick! For best reception, try to ensure
that your wireless devices are positioned so that signals will travel
straight through a wall or ceiling.

3. Try to position wireless client devices so that the signal passes through
drywall (between studs) or open doorways and not other materials that
can adversely affect the wireless signal.
