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) Standards-Based Technology The DWL-G120 Wireless USB 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.
Wireless Basics (continued) Installation Considerations TM The D-Link AirPlus G DWL-G120 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 With its default settings, the DWL-G120 will connect with other D-Link AirPlusTM G products, right out of the box. There are basically two modes of networking: Infrastructure – using an access point or router, such as the DI-624. Ad-Hoc – directly connecting to another computer, for Peer-to-Peer communication, using wireless network adapters on each computer, such as two or more DWL-G120 Wireless USB Adapters.
