Installation Speed and Simplicity - Installing a wireless LAN system
can be fast and easy and can eliminate the need to pull cable through
walls and ceilings.
Wireless Basics (continued)
Installation Flexibility - Wireless technology allows the network to go
where wires cannot go.
Reduced Cost-of-Ownership - While the initial investment required for
wireless LAN hardware might be higher than the cost of wired LAN
hardware, overall installation expenses and life-cycle costs will be
significantly lower. Long-term cost benefits are greatest in dynamic
environments requiring frequent moves, adds, and changes.
Scalability - Wireless LAN systems can be configured in a variety of
topologies to meet the needs of specific applications and installations.
Configurations are easily changed and range from peer-to-peer networks
suitable for a small number of users to full infrastructure networks of
thousands of users that allow roaming over a broad area.

Installation Considerations
Designed to go up to 1650 feet (~500 meters), D-Link DWL-AB520 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:
1. 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 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
