1 Basic Information on Wireless LAN Communication 1.1 Network Structure Ad Hoc Networks In the ad hoc mode, nodes communicate directly with the server (connections 1 through 3 in the graphic below) without involving a SCALANCE W 788 or with each other (connection 4). The nodes access common resources (files or even devices, for example a printer) of the server. This is, of course, only possible when the nodes are within the wireless range of the server or within each other's range.
Basic Information on Wireless LAN Communication Standalone Configuration with the SCALANCE W 788 This configuration does not require a server and the SCALANCE W 788 does not have a connection to a wired Ethernet. Within its transmission range, the SCALANCE W 788 forwards data from one WLAN node to another. The wireless network has a unique name. All the devices exchanging data within this network must be configured with this name. Figure 1-2 Standalone Configuration of a SCALANCE W 788.
Basic Information on Wireless LAN Communication Wireless Access to a Wired Ethernet Network If one (or more) SCALANCE W 788 access points have access to wired Ethernet, the following applications are possible: ● A single SCALANCE W 788 as gateway: A computer equipped only with an Ethernet adapter can be integrated in the client mode in a wireless network over the SCALANCE W 788-1pro.
Basic Information on Wireless LAN Communication Multichannel Configuration If neighboring SCALANCE W 788 access points use the same frequency channel, the response times are longer due to the collisions that occur. If the configuration shown in Figure 1-4 is implemented as a single-channel system, computers A and B cannot communicate at the same time with the SCALANCE W 788-1pro access points in their cells.
Basic Information on Wireless LAN Communication Wireless Distribution System (WDS) WDS allows direct connections between SCALANCE W 788 access points. These are used to create a wireless backbone or to connect an individual SCALANCE W 788 to a network that cannot be connected directly to the cable infrastructure due to its location. Two alternative configurations are possible. The WDS partner can be configured both using its name and its MAC address.

The page of this menu command also indicates the interface over which a computer can be reached. The last column indicates how the information was obtained (for example dynamic if it was obtained from active data exchange). 6.5.
Configuration Using Web Based Management and the Command Line Interface Age of the Configuration Information With the Max Age parameter, you specify the maximum age of configuration information. If a bridge receives configuration information older than specified in Max Age, it discards the message and starts a new calculation of the paths. New configuration data is not used immediately by a bridge but only after the period specified in the Forward Delay parameter.
Configuration Using Web Based Management and the Command Line Interface ● PathCost This parameter is used to specify the preferred data paths between the root bridge and other bridges and the value should be based on the transmission speed. The faster a connection, the lower the value for PathCost should be. You can specify values between 0 and 65535. The default is 100. The spanning tree algorithm selects the transmission path for which the sum of all individual values is the lowest.
