Division Multiplexing) technology.
OFDM
works by splitting the radio signal into multiple smaller
sub-signals that are then transmitted simultaneously at different frequencies to the receiver.
OFDM
reduces the amount of
crosstalk
(interference) in signal transmissions. Our products will
automatically sense the best possible connection speed to ensure the greatest speed and range
possible with the technology.
Installation Considerations
Designed to traverse distances up to 900 feet (~300 meters), the
SP906GL/SP908GL Wireless
LAN Adapter
lets you access your network from your laptop computer 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 the
transmission 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 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 cards - 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 as if it were over 42 feet (14 meters) thick! Try to make sure
that the Access Points and Cards are positioned so that the signal will travel in as straight a
line through a wall or ceiling as possible for better reception.
3. Building Materials make a difference - A solid metal door or aluminum studs can have a
negative effect on range. Try to position Access Points and computers with wireless cards 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
Wireless LAN Adapter
.
5. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances
that generate RF noise.
For the average residence, 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 computers with wireless cards that will be connected. Additional
Access Points can be connected to provide better coverage in rooms where the signal does not
appear as strongly as desired.
