Installation Considerations

The D-Link Air DWL-520 lets you access your network using a wireless connection from
virtually anywhere within its operating range. 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-520 and other network
devices to a minimum - each wall or ceiling can reduce your D-Link Air 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! 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 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.
