    Introduction Introduction The advantages of a radio network (Wireless LAN) are obvious: notebooks and PCs can be set up where they are needed. Due to Wireless LANs, prob- lems with missing connections or structural alterations belong to the past. Network access in conferences or during presentations, access to resources in neighbouring buildings or data exchange with portable terminals are only some possible applications of Wireless LANs.

  • Page 8: Central Collecting Point - The Base Station

    Introduction 1.2.2 Central collecting point – the base station With an additional base station, a Wireless LAN becomes more comfortable and more efficient. The base station (access point) enables a central admin- istration of the Wireless LAN. Furthermore, with a base station you can also connect an entire cable-bound LAN to a Wireless LAN.

  • Page 9: Infrastructure Network

    Introduction 1.3.2 Infrastructure network A base station (access point) is needed for connection to an existing network. The base station forms the control center for data exchange within the WLAN. The base station additionally can offer - depending on its product type - access to a cable-based LAN, as well as to the Internet.

    Introduction An infrastructure-network is excellently suitable as an extension to existing wired LANs. For extension of a LAN in areas, where a wiring is not possible or uneconomical, the infrastructure-network represents an ideal alternative. Standardized radio transmission by IEEE AirLancer client adapters work with the IEEE 802.11 standard. This standard IEEE 802.11 family represents an extension of the already existing IEEE standards for LANs, of which IEEE 802.3 for Ethernet is the most popular one.

With increasing dis- tance and diminishing connecting quality the transmission rate lowers to 5,5 Mbps, afterwards to 2 and finally to 1 Mbps. The range of the transmission distances is between up to 150 m in open expanses and in buildings typically up to 30 m.
