Wireless Basics (continued)
Standards-Based Technology
The DWL-AG530 Wireless PCI Adapter utilizes the 802.11a, 802.11b and 802.11g
standard.
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 (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-AG530 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, WPA2, 802.1x, TKIP, AES and Pre-Shared Key mode.
The DWL-AG530 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.
