Standards-Based Technology
The DWL-G820 Wireless Gaming Adapter utilizes the 802.11b and the 802.11g standards.
The IEEE 802.11g standard is an extension of the 802.11b standard. It increases the
data rate up to 54Mbps (108Mbps in Super G mode) 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-G820
will automatically sense the best possible connection speed to ensure the greatest
speed and range possible.
802.11g offers WPA, the most advanced network security features available today.
