Wireless Basics
The DWL-810 is fully compatible with the recently introduced D-Link AirPlus
family of products that include:
Enhanced 2.4GHz Wireless Cardbus Adapters used with laptop
computers (DWL-650+)
Enhanced 2.4GHz Wireless PCI cards used with desktop computers
(DWL-520+)
Wireless Access Points (DWL-900AP+)
Standards - Based Technology
The IEEE standard-based technology assures that the D-Link Air Products
are interoperable with existing compatible wireless technology. This means
you will be able to transfer large files quickly or even watch a movie in
MPEG format over your network without noticeable delays. The technology
works by using multiple frequencies in the 2.4GHz range.
products will automatically sense the best possible connection speed to
ensure the greatest speed and range possible with the technology.
Installation Considerations
Designed to go up to 984 feet (300 meters) outdoors and up to 328 feet (100
meters) indoors, the D-Link Air DWL-810 lets you access your network
devices wirelessly from virtually anywhere. Keep in mind, however, that the
number, thickness and location of walls, ceilings or other objects that the
wireless signal must pass thru may limit range. Typical ranges vary
depending on the types of materials and any background RF (radio
frequency) noise in your home or business. The key to maximizing range is
to follow these basic guidelines:
1. Keep the number of walls and ceilings between the DWL-810 and your
receiving device (e.g., the DWL-520+) to a minimum - Each wall or
ceiling can reduce your D-Link Air Wireless product's range from 3-90
feet (1-30 meters.) Position your DWL-810, Access Points, Residential
Gateways, and computers so that the number of walls or ceilings is
minimized.
2. Be aware of the direct line between the DWL-810 and the device with
which it communicates, as well as between Access Points, Residential
Gateways (routers), and computers. 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
