Standards-based Technology
The
DWL-2700AP
Wireless Access Point utilizes the
802.11b
and the
802.11g
standards.
The IEEE
802.11g
standard is an extension of the
802.11b
standard. It increases the
maximum wireless signal rate of up to 54Mbps* 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
(
O

F

M

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 D-Link
DWL-2700AP
will automatically sense the best possible connection speed
to ensure the greatest speed and range possible.
The DWL-2700AP offers the most advanced network security features available today,
including WPA and WPA2.
In addition to its compatibility with 802.11g devices, the DWL-2700AP is compatible
with 802.11b devices. This means that if you have an existing 802.11b network, or a
network with a mixture of 802.11g and 802.11b, the devices in that network will be
compatible with the
DWL-2700AP
.
*Maximum wireless signal rate derived from IEEE Standard 802.11g specifications. Actual data throughput will vary. Network
conditions and environmental factors, including volume of network traffic, building materials and construction, and network overhead,
lower actual data throughput rate. Environmental factors may adversely affect wireless signal range.
