Infrastructure mode (AccessPoint)

With a wireless AccessPoint your can operate a WLAN in the infrastructure mode. You may then connect a wireless connection to several wireless devices within a specified area or the range of the AccessPoint. Communication with the wireless nodes is via an antenna. In infrastructure mode, the wireless AccessPoint converts the data transmitted in the form of radio waves into Ethernet data and thereby forms the bridge between the individual wireless clients and the wired LAN. By connecting several AccessPoints via an Ethernet backbone, the range of a wireless network can be expanded. If a mobile device falls outside the range of an AccessPoint, it falls within the range of another. This means that wireless clients can be moved freely from the domain of one AccessPoint to the next, thereby maintaining a wireless connection to the network.
