LG GoldStream 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.
LG GoldStream 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. WLAN adapters provide an interface between the client network operating system (NOS) and the airwaves (via an antenna).
LG GoldStream 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, PCI. ¦ Wireless LAN Network Configuration The 802.11 standard define two modes: infrastructure mode and ad hoc mode (or independent or peer-to-peer).
LG GoldStream 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 (802.3) Access Point (AP) Service Set (SS) – Multiple Figure 2.
LG GoldStream 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.
LG GoldStream ¦ 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.

This mode requires an GOLDSTREAM Access Point to gain access to the wired network. Ad Hoc Mode This mode is used to set up a small, temporary network between two or more computers. For example, you might set up an ad hoc network between computers in a conference room so users can share information in a meeting.
LG GoldStream In order to do secure communication over the wireless LAN network, wireless LAN module provides encryption function - WEP. There are two ways to generate WEP key. This key is an important in protecting the illegal access to the wireless networks. If you want to use WEP function, the AP also set the same WEP key value with you. And all the users who want to communicate with you must use same key with each other.
LG GoldStream the wireless network resources. As the wireless channel is more prone to the illegal access, WEP provides the users safe wireless LAN network access.
