Standards-Based Technology
The DI-524UP Wireless Router utilizes the new 802.11g standard.
The IEEE 802.11g standard is an extension of the 802.11b standard. It increases the
data rate up to 54 Mbps within the 2.4GHz band, utilizing OFDM technology.
This means that in most environments, within the specified range of this device, you will
be able to transfer large files quickly or even watch a movie in MPEG format over your
network without noticeable delays. This technology works by transmitting high speed
digital data over a radio wave utilizing OFDM (Orthogonal Frequency 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.
The DI-524UP is backwards compatible with 802.11 b devices. This means that if you
have an existing 802.11 b network, the devices in that network will be compatible with
802.11g devices at speeds of up to 11 Mbps in the 2.4GHz range.
Installation Considerations
The D-Link DI-524UP lets you access 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:
1.
Keep the number of walls and ceilings between the DI-524UP 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) thick! Position devices so that
the signal will travel straight through a wall or ceiling (instead of at an angle) for
better reception.
3.
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 your product away (at least 3-6 feet or 1-2 meters) from electrical
devices or appliances that generate extreme RF noise.
