Wireless Basics (continued)

Installation Considerations

Designed to go up to 900 feet (~300 meters), D-Link AirPro DWL-A520 lets

you access your network with your computer from virtually anywhere you

want. Keep in mind, however, that the number and thickness of walls,

ceilings or other objects that the wireless signals must pass thru may limit

range. Typical ranges vary depending on the types of materials and

background RF noise in your home or business. The key to maximizing

range is to follow these basic principles:

Keep the number of walls and ceilings between the Access Point and

your receiving device to a minimum - Each wall or ceiling can reduce

your D-Link AirPro Wireless product’s range from 3-90 feet (1-30 meters.)

For some businesses or for a large residential home deployment, it may

be beneficial to have more than one access point with overlapping

coverage.

2. Be aware of the direct line between Access Points and computers with

wireless adapters - 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 the

Access Points and Adapters 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 Access Points,

and computers with wireless adapters so that the signal passes through

drywall or open doorways and not other materials.

4. Make sure that the antenna is positioned for best reception by using the

software signal strength tools included with your product.

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

devices or appliances that generate extreme RF noise.
