Wireless Basics

Network Expansion - Wireless technology allows the network to go where wires cannot go.

Reduced Cost-of-Ownership- While the initial investment required for Wireless LAN hardware might be higher than the cost of wired LAN hardware, overall installation expenses and life-cycle costs will be significantly lower. Long-term cost benefits are greatest in dynamic environments requiring frequent moves, adds, and changes.

Scalability - Wireless Local Area Networks (WLANs) can be configured in a variety of topologies to meet the needs of specific applications and installations. Configurations are easily changed and range from peer-to-peer networks suitable for a small number of users to full infrastructure networks of thousands of users that allow roaming over a broad area.

Some D-Link devices that are compatible with the D-Link DWL-650+ are:

D-Link DWL-520+ 2.4GHz Wireless PCI cards used with desktop computers

D-Link DI-614+ Wireless Broadband Router

D-Link DWL-900AP+ Wireless Access Point

Standards - Based Technology

The IEEE standard-based technology assures that the D-Link AirPlus Products are interoperable with existing compatible 2.4GHz wireless technology. This means you will be able to transfer large files quickly or even watch a movie in MPEG format over your network without noticeable delays. The technology works by using multiple frequencies in the 2.4GHz range at speeds up to 22Mbps. D-Link AirPlus products will automatically sense the best possible connection speed to ensure the greatest speed and range possible with the technology.

802.1x provides an extra level of security to your wireless network. Through its Authentication protocol (when 802.1x is activated), only clients with 802.1x authentication will be permitted to communicate in your network; all other clients will be denied access. This is a far more secure wireless network than has previously been available.

All devices on the network must be 802.1x compatible and must share the same EAP type. For Authentication purposes you will need a radius server in your network.
