Installation Considerations

Designed to go up to 100 meters indoors and up to 300 meters
outdoors, D-Link Air lets you access your network from anywhere you
want. Keep in mind, however, that the number of walls, ceilings or other
objects that the wireless signals must pass thru will 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 to a minimum - Each wall or
ceiling can reduce your D-Link Air Wireless products range from 1-30
meters. Position your Access Points, Residential Gateways, and
Computers so that the number of walls or ceilings is minimized.
2. Be aware of the direct line between Access Points, Residential
Gateways, and Computers - A wall that is .5 meter thick, at a 45 degree
angle appears to be almost 1 meter thick. At a 2 degree angle it looks
over 14 meters thick! Try to make sure that the AP 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. Again, try to position
Access Points, Residential Gateways, and Computers 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 1-2 meters) from electrical devices
that generate RF noise, like microwaves, Monitors, electric motors, etc.
For the average American 4-bedroom home, range should not be a
problem. If you experience low or no signal strength in areas of your home
that you wish to access, consider positioning the Access Point in a location
directly between the Residential Gateways and/or Computers that will be
connected. Additional Access Points can be connected to provide better
coverage in rooms where the signal does not appear as strong as desired.
