Standards-Based Technology
The DWL-G630 Wireless G Notebook Adapter utilizes the 802.11b and
802.11g standards.
The IEEE 802.11g standard is an extension of the 802.11b standard. It
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 DWL-G630 will automatically sense the best
possible connection speed to ensure the greatest speed and range possible.
Wireless Basics (continued)
802.11g offers the most advanced network security features available today,
including: WPA
/WPA2
, 802.1x, TKIP, AES and Pre-Shared Key mode.
The DWL-G630 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.
