Wireless Basics D-Link wireless products are based on industry standards to provide easy-touse and compatible high-speed wireless connectivity within your home, business or public access wireless networks.
Wireless Basics (continued) People use wireless LAN technology for many different purposes: Mobility - Productivity increases when people have access to data in any location within the operating range of the WLAN. Management decisions based on real-time information can significantly improve worker efficiency. Low Implementation Costs – WLANs are easy to set up, manage, change and relocate. Networks that frequently change can benefit from WLANs ease of implementation.
Wireless Basics (continued) Installation Considerations The D-Link Air DWL-122 lets you access your network, using a wireless connection, from virtually anywhere within its operating range. Keep in mind, however, that the number, thickness and location of walls, ceilings, or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary depending on the types of materials and background RF (radio frequency) noise in your home or business.
Getting Started Inserting the DWL-122 Insert the DWL-122 into an available USB port. Using the DWL-122 with the extension cord Plug one end of the USB extension cord into the USB port on your computer and plug the other end into the DWL-122.
