1.2 Installation Considerations 14
on the types of materials and background RF (radio frequency)
noise in your home or business. The key to maximizing wireless
range is to follow these basic guidelines:
1. Keep the number of walls and ceilings between the
HorstBox and other network devices to a minimum.
Each wall or ceiling can reduce the radio range from 1-30
meters (3-90 feet). Position your devices so that the number
of walls or ceilings is minimized.
2. Be aware of the direct line between network devices.
A wall that is 0,5 meters thick (1.5 feet ), at a 45-degree
angle appears to be almost 1 meter (3 feet) thick. At a 2-
degree angle it looks over 14 meters (42 feet) thick! Position
devices so that the signal will travel straight through a wall
or ceiling (instead of at an angle) for better reception.
3. Building materials can impede the wireless signal.
A solid metal door or aluminum studs may have a negative
effect on range. Try to position wireless devices and comput-
ers with wireless adapters so that the signal passes through
drywall or open doorways and not other materials.
4. Align the antenna for best reception.
Align and position the antenna until you get best coverage.
Some WLAN devices or access points will help you with this
task. Sometimes fixing the antenna in a higher position
advances the reception.
5. Keep distance to other devices.
Keep your product away (at least 1-2 meters or 3-6 feet)
from electrical devices or appliances that generate RF noise.
6. Choose a useful combination of channels.
To avoid disturbances of radio waves, choose a useful com-
bination of radio channels.
Standard 802.11b/g devices may always use 3 channels at
once. It’s most effective to use a combination like 2/5/9, as
the factory settings of most devices will be 6 or 11. Make
sure the distance between the channels is a least 2 to 3
unused channels.
