Wireless Basics (continued)
Installation Considerations
The D-Link AirPro DWL-AB650 lets you access your network, using a
wireless connection, from virtually anywhere. Keep in mind, however, that the
number, thickness and location of walls, ceilings, or other objects that the
wireless signals must pass through, may limit the range. Typical ranges vary
depending 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 DWL-AB650 and
other network devices to a minimum - each wall or ceiling can reduce
your D-Link AirPro Wireless product's range from 3-90 feet (1-30 meters.)
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
1.5 feet thick (.5 meters), at a 45-degree angle appears to be almost 3
feet (1 meter) thick. At a 2-degree angle it looks over 42 feet (14 meters)
thick! Try to make sure that devices are positioned so that the signal will
travel straight through a wall or ceiling for better reception.
3. Building Materials make a difference - a solid metal door or aluminum
studs may have a negative effect on range. Try to position wireless
devices and computers with wireless adapters so that the signal passes
through drywall or open doorways and not other materials.
4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical
devices or appliances that generate RF noise.
