D-Link, the industry pioneer in wireless networking, introduces another breakthrough in wireless connectivity — the D-Link Air Xpert DWL-AG520 Wireless PCI Adapter. This tri-mode, dualband adapter inserted into your desktop PC provides you a versatile way to wirelessly connect to any one of three available wireless networks — 802.11b and the newer, faster 802.11g and 802.11a that operate in two discrete, non-interfering frequency bands, 2.4GHz and 5GHz.

If you re a network administrator, the versatile 802.11a/b/g- compatible DWL-AG520 gives you an immediate way to expand to your existing 802.11b network and protect your overall wireless network investment. By installing DWL-AG520s in desktops throughout your organization your employees can access wireless APs or routers from their desktop PCs. And as your company expands or reorganizes you wo n't have to keep pulling and plugging Ethernet cable because no matter where the workstation is relocated, it's still connected to the network. When you add an 802.11a/b/g access point (D-Link Air Xpert DWL-7000AP) or router (D-Link Air Xpert DI-774), to your wireless network, you  will have an end-to-end wireless solution capable of handling up to four times the user load of your current 802.11b network.

In addition to its compatibility with earlier 802.11b networks, the DWL-AG520 now offers the robust speed, up to 54Mbps, of the newer 802.11g and 802.11a standards, so everyone can work faster and more efficiently. The additional (802.11a) 5GHz band also offers a way to quickly transfer data in a frequency range that does not experience interference or interruptions from cordless phones, microwave ovens and other devices utilizing the 2.4GHz frequency.

The 802.11g, 802.11a, 802.1x standards and WPA* (Wi-Fi Protected Access)— all engineered in the DWL-AG520 chipset provide the necessary security protocols and tools, so employees can communicate with colleagues confidentially, access sensitive company information or send data that is dynamically encrypted as i t's sent. The DWL-AG520 is a high-performance, versatile and necessary desktop PC networking solution for companies that need to quickly expand or reconfigure their wireless networks as their organization grows.
