Wireless Basics (continued)
Standards-Based Technology
The DWL-G520+ Wireless PCI Adapter 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 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-G520+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 and the Features section of this manual.
The DWL-G520+ 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-G520+ is interoperable with existing compatible 2.4GHz wireless technology with data transfer speeds of up to 11Mbps.
