Wireless Basics (continued)

Installation Considerations

The D-Link Air Premier

 

  DWL-AG650S 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-AG650S and
other network devices  to a minimum - each wall or ceiling can reduce
your DWL-AG650S’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.

2

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.
