Standards-Based Technology
The DWL-G550 Wireless 108G Desktop Adaper utilizes the 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, 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 (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 D-Link DWL-G550 will automatically sense the best possible connection speed to
ensure the greatest speed and range possible.
802.11g offers the most advanced network security features available today, including:
WPA , 802.1x, TKIP, AES and Pre-Shared Key mode. These security features are
explained in more detail in the Introduction section of this manual.
The DWL-G550 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 DWL-G550 is interoperable with existing compatible 2.4GHz
wireless technology with data transfer speeds of up to 11Mbps.
