This Netkey WLAN Adapter supports following WLAN features z Automatic transmit data rate select mechanism in the transmit range of 1, 2, 5.5 and 11 Mbps. z Center frequency channel selection (2.4 GHz) z Roaming over multiple channels. z Supports USB interface z Supports power save mode z 128-bit Wired Equivalent Privacy (WEP) data encryption. z Plug and Play installation This Netkey comes with software drivers for the most popular Microsoft Windows operating systems and can be integrated into a larger network, running Windows XP, Windows 2000, Windows ME, or Windows 98 in either Ad-Hoc mode or infrastructure mode. This manual provides a quick introduction to wireless technology and its application as it relates to networking. Take a moment to read through this manual and familiarize you with wireless technology. You should also give yourself some time to become familiar with your new wireless network. Netkey Series WLAN Card WWW.TwinMOS.COM Page 4 WIRELESS NETWORK OVERVIEW A wireless local area network (LAN) is a flexible data communications system implemented as an extension to, or as an alternative for, a wired LAN. Using radio frequency (RF) technology, wireless LANs transmit and receive data over the air, minimizing the need for wired connections. Thus, wireless LANs combine data connectivity with user mobility. A local area network that transmit and receive over the air typically in an unlicensed frequency such as the 2.4GHz band. A wireless LAN does not require lining up devices for line of sight transmission like IrDA. Wireless access points (base stations) are connected to an Ethernet hub or server and transmit a radio frequency over an area of several hundred to a thousand feet which can penetrate walls and other nonmetal barriers. Roaming users can be handed off from one access point to another like a cellular phone system. Laptops use wireless modems that plug into an existing Ethernet port or that are self contained on PC cards, while stand-alone desktops and servers use plug-in cards (ISA, PCI, etc.). Wireless LANs offer the following productivity, convenience, and cost advantages over traditional wired networks Mobility - WLAN provide LAN users to access data in any location within the operating range of the WLAN. Ad-hoc management decisions based on real-time information can significantly improve worker efficiency. Installation Speed and Simplicity - Installing a wireless LAN system can be fast and easy and can eliminate the need to pull cable through walls and ceilings. Installation Flexibility - Wireless technology allows the network to go where wire cannot go. Reduced Cost-of-Ownership - While the initial investment required for wireless LAN hardware can be higher than the cost of wired LAN hardware, overall installation expenses and life-cycle costs can be significantly lower. Long-term cost benefits are greatest in dynamic environments requiring frequent moves and changes. Scalability - Wireless LAN systems 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 enable roaming over a broad area. Installation Considerations Designed to go up to 300 feet (100 meters) indoors and up to 900 feet (273 meters) outdoors, Netkey WLAN adapter lets you access your network from virtually anywhere you want. Keep in mind, however, that the number and thickness of walls, ceilings or other objects that the wireless signals must pass thru may limit range. Typical ranges vary depending on the types of materials and background RF noise in your home or business. The key to maximizing range is to follow these basic principles: Netkey Series WLAN Card WWW.TwinMOS.COM Page 5 Keep the number of walls and ceilings between the access point and your receiving device to a minimum - Each wall or ceiling can reduce your TwinMOS Netkey Wireless product’s range from 3-90 feet (1-30 meters.) For some businesses or for a large residential home deployment, it may be more beneficial to have more than one access point with overlapping coverage. 1. Be aware of the direct line between Access Points, Residential Gateways, and Computers -…
