Wireless Basics (continued)
The DI-754 is compatible with other D-Link AirPro 802.11a products, which
include
:
♦
5GHz Wireless Cardbus Adapters used with laptop computers
(DWL-A650)
♦
5GHz Wireless PCI Adapters used with desktop computers
(DWL-A520)
The DI-754 is also compatible with the D-Link AirPlus 802.11b wireless family
(when you install the DWL-650+ into the expansion slot), which includes
:
♦
Enhanced 2.4GHz Wireless Cardbus Adapters used with laptop
computers (DWL-650+)
♦
Enhanced 2.4GHz Wireless PCI cards used with desktop computers
(DWL-520+)
Standards-Based Technology
The versatile DI-754 Wireless Broadband Router integrates both 802.11a and
optional (with D-Link DWL-650+) 802.11b standards into a single unit.
The IEEE
802.11a
standard designates that devices may operate at an optimal
data rate of 54 Mbps (72 Mbps in proprietary
Turbo
mode.) 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
rthogonal
F
requency
D
ivision
M
ultiplexing) 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. D-Link
AirPro
802.11a products will
automatically sense the best possible connection speed to ensure the greatest
speed and range possible.
Based on the IEEE
802.11b
standard (when the optional D-Link DWL-650+ is
installed in the expansion slot), the DI-754 is also interoperable with existing
compatible 2.4GHz wireless technology with data transfer speeds of up to
22Mbps (with the D-Link
Air
Plus family of wireless devices), as well as standard
802.11b technology (the D-Link
Air
family of wireless devices), with speeds of
up to 11Mbps.
