The D-Link AirPlusXtreme G DWL-G520 Wireless PCI card is an enhanced 802.11g high-performance, wireless card for desktop computers. This card supports high-speed wireless networking of up to 108Mbps, while providing seamless interoperability with all existing 802.11b and 802.11b+ wireless equipment. Together with better security, this card is the ideal wireless solution that offers an upgrade to a fast, new technology while protecting your past investments through interoperability with your current network equipment. Unlike most wireless cards, the DWL-G520 provides speeds of up to 108Mbps when used with other D-Link AirPlus Xtreme G and other 802.11g products. This compares favorably with 802.11b adapters that offer 11Mbps speed, and with 802.11b+ adapters that give 22Mbps transmission. This enhanced speed and adoption of 2.4GHz frequency, now available for public use in most countries, plus the mobility and convenience inherent in a wireless LAN, make this card an ideal solution for bandwidth intensive WLAN applications. Like the 802.11b and 802.11b+ adapters, the DWL-G520 uses a single 2.4GHz wireless frequency, eliminating the complexity of dual-band networking. 802.11g's compatibility with existing wireless LAN standards means that you do not need to change your entire network to maintain connectivity. You may sacrifice some of 802.11g's speed when you mix 802.11b and 802.11b+ with 802.11g devices, but you will not lose the ability to communicate. By maintaining compatibility with your existing wireless network equipment, this adapter lets you upgrade to a higher speed at the pace you want. The DWL-G520 and other 802.11g standard devices can be gradually added to your network, while the rest of your older network remains perfectly connected.
