ezWAVE Access Point Users’ Guide Version 1.6 Chapter 1 Introduction To The Wireless LAN A wireless LAN (WLAN) is a flexible data communication system implemented as an extension to, or as an alternative for, a wired LAN within a building or campus. Using electromagnetic waves, WLANs transmit and receive data over the air, minimizing the need for wired connections. Thus, WLANs combine data connectivity with user mobility, and, through simplified configuration, enable movable LANs.
ezWAVE Access Point Users’ Guide Version 1.6 to several hundred feet. The access point (or the antenna attached to the access point) is usually mounted high but may be mounted essentially anywhere that is practical as long as the desired radio coverage is obtained. End users access the WLAN through wireless LAN adapters, which are implemented as PC cards in notebook computers, or use PCI adapters in desktop computers.
ezWAVE Access Point Users’ Guide Version 1.6 consists of a radio, a wired network interface (e.g., 802.3), and bridging software conforming to the 802.1d Bridging standard. The access point acts as the base station for the wireless network, aggregating access for multiple wireless stations onto the wired network. Wireless end stations can be 802.11 PC Card and PCI. { Wireless LAN Network Configuration The 802.
ezWAVE Access Point Users’ Guide Version 1.6 point connected to the wired network infrastructure and a set of wireless end stations. This configuration is called a Basic Service Set (BSS). An Extended Service Set (ESS) is a set of two or more BSSs forming a single sub-network. Since most corporate WLANs require access to the wired LAN for services (file servers, printers, Inter-net links) they will operate in infrastructure mode. Distribution System (DS) Ethernet (802.
ezWAVE Access Point Users’ Guide Version 1.6 When an 802.11 client enters the range of one or more APs, it chooses an access point to associate with (also called joining a Basic Service Set), based on signal strength and observed packet error rates. Once accepted by the access point, the client tunes to the radio channel to which the access point is set. Periodically it surveys all 802.11 channels in order to assess whether a different access point would provide it with better performance characteristics.
ezWAVE Access Point Users’ Guide Version 1.6 { BSS, ESS and SS ID The basic service set (BSS) is the basic building block of WLAN network. Minimum WLAN BSS may be consist of only two stations. Using access point (AP) and network distribution systems (DS), WLAN service set can be extended arbitrary size – extended service set (ESS). Each service set has its network ID (SSID). All the service sets within an ESS network can have same service ID so that the ESS can support inter-cell ROAMING.
