Wireless Basics (continued)
Installation Considerations
The D-Link AirPlus Xtreme G DWL-G820 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: TM
Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices
or appliances that generate RF noise. 4
Keep the number of walls and ceilings between the DWL-G820 and other network
devices to a minimum - each wall or ceiling can reduce your DWL-G820’s range
from 3-90 feet (1-30 meters.) Position your devices so that the number of walls
or ceilings is minimized. 1
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.

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. 3
