54Mbps 802.11g Wireless LAN Card About This Manual This manual was written for the following types of wireless adapter: • PC Card • PCI Card • Mini PCI Card For brevity, throughout this manual Wireless LAN Card is used to indicate both types. Also, the following terms/abbreviations are used interchangeably: • • • • Access Point – AP Peer-to-Peer – Ad Hoc Wireless LAN – WLAN Ethernet network – LAN – network This User’s Manual contains information on how to install and configure your Wireless LAN Card.
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 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.
54Mbps 802.11g Wireless LAN Card 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.
