Wireless Basics (continued)
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
(

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
backward 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.
*“Maximum wireless signal rate derived from IEEE Standard 802.11a and 80211g 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.”
