Standards-Based Technology
Based on the IEEE 802.11g standard, the DP-G321 is interoperable with existing
compatible 2.4GHz wireless technology with data transfer speeds of up to 54Mbps
when used with other D-Link
Air Plus G devices.
Wireless Basics (cont.)
Installation Considerations
The D-Link Air Plus G DP-G321 lets you print through 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:
Keep the number of walls and ceilings between the DP-G321 and other
network devices to a minimum - each wall or ceiling can reduce your D-Link
wireless product’s range from 3-90 feet (1-30 meters). Position your devices
so that the number of walls or ceilings is minimized.
2.
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). Position devices so that the
signal will travel straight through a wall or ceiling (instead of at an angle) for
better reception. 3.
Keep your product away (at least 3-6 feet or 1-2 meters) from electrical
devices or appliances that generate extreme RF noise.
5.
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.
4.
Keep the antenna of the DP-G321 in an upright position. 1.
