Standards-Based Technology
The WMPL-G04 Wireless Mini PCI Card 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 ( 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. The D-Link WMP-G01 will automatically
sense the best possible connection speed to ensure the greatest speed and
range possible.
The WMP-G04 is backwards compatible with 802.11b devices. This means
that if you have an existing 802.11b network, the devices in that network will be
compatible with 802.11g devices at speeds up to 11Mbps in the 2.4GHz range.
Also based on the IEEE
802.11b standard, the WMP-G04 is interoperable with
existing compatible 2.4GHz wireless technology with data transfer speeds of
up to 11Mbps.
