54Mbps 802.
Chapter 1 Introduction This Wireless LAN Card is an IEEE 802.11g wireless LAN adapter. 802.11g is the latest in the series of 802.11 specifications for wireless local area networks (WLANs) and provides data transfer of up to 54 Mbps. Since 802.11g operates on the same frequency of 2.4 GHz as 802.11b, so it is backwards compatible with existing Wi-Fi devices! It allows your computer to connect to a wireless network and to share resources, such as files or printers without being bound to the network wires.
54Mbps 802.11g Wireless LAN Card Wireless LAN Basics This section conations some Wireless LAN basics to help you better understand how the product work together to create a wireless network. Local Area Network (LAN) Simply put, a LAN is a network that exists in a relatively limited area. A network is two or more computers connected together sharing files and peripheral devices such as printers.
Chapter 1 Introduction Ad-Hoc Mode The Ad-Hoc Group offers peer-to-peer connections between workstations, allowing communication between computers within range that have an 802.11g DSSS compatible PC card installed. A wireless Ad-Hoc network can also access a wired LAN’s TCP/IP service (such as e-mail and the Internet) by using a TCP/IP software router on an Ethernet equipped PowerBook or notebook.
54Mbps 802.11g Wireless LAN Card Infrastructure Mode The Infrastructure network uses an AP or several APs as a gateway, linking the wireless network to a wired LAN. As a result, portable workstations or desktops on your wireless network have access to all of the features of your wired LAN including e-mail, Internet access, network printers and files server.
Chapter 1 Introduction Roaming Multiple Access Points can be installed to extend the wireless service coverage area for seamless wireless access. Within an extended service area, all Access Points and wireless clients must have the same Service Set Identity (SSID). Roaming among different Access Points is controlled automatically to maintain the wireless connectivity at all times.
Chapter 2 Installing the Wireless LAN Card This chapter describes the installation process for the driver and software for the Wireless LAN Card.
