Standards-Based Technology
The DWL-7100AP Wireless Access Point utilizes the 802.11a, 802.11b and draft 802.11g
standard.
The IEEE 802.11g standard is an extension of the 802.11b standard. It increases the
data rate up to 54Mbps within the 2.4GHz band. The 802.11a standard also increases
the data rate up to 54Mbps, but within the 5GHz band. Both 802.11a and 802.11g utilize
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 DWL-7100AP offers the most advanced network security features available today,
including WPA.
In addition to its compatibility with 802.11g and 802.11a devices, the DWL-7100AP 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, 802.11a and 802.11b, the devices in that network
will be compatible with the DWL-7100AP.
