Wireless Basics (continued)

Installation Considerations

The D-Link AirPlus DWL-120+ 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 antenna of the DWL-120+ in an upright position.

Keep the number of walls and ceilings between the DWL-120+ and other

network devices to a minimum - each wall or ceiling can reduce your D-

Link wireless product’s range from 3-90 feet (1-30 meters.) Position your

devices so that the number of walls or ceilings is minimized.

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.

Keep your product away (at least 3-6 feet or 1-2 meters) from electrical

devices or appliances that generate extreme RF noise.

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.
