Page 13: Basic Information On Wireless Lan Communication
Basic Information on Wireless LAN Communication Network Structure Standalone Configuration with the SCALANCE W78x This configuration does not require a server and the SCALANCE W78x does not have a connection to a wired Ethernet. Within its transmission range, the SCALANCE W78x forwards data from one WLAN node to another. The wireless network has a unique name.
Page 14 Basic Information on Wireless LAN Communication d Hoc Networks In the ad hoc mode, nodes communicate directly (connections 1 through 3 in Figure 1-2) without involving a SCALANCE W78x with each other (connection 4). The nodes access common resources (files or even devices, for example a printer) of the server.
Page 15 Basic Information on Wireless LAN Communication Wireless Access to a Wired E thernet Network If one (or more) SCALANCE W78x access points have access to wired Ethernet, the following applications are possible: ● A single SCALANCE W78x as gateway: A wireless network can be connected with a wired network over a SCALANCE W78x.
Page 16 Basic Information on Wireless LAN Communication Multichannel Configuration If neighboring SCALANCE W78x access points use the same frequency cha nnel, 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 a B cannot communicate at the same time with the SCALANCE W78x access po ints in their ce...
Page 17 Basic Information on Wireless LAN Communication Wireless Distribution System (WDS WDS allows direct connections between SCALANCE W78x devices and or between SCALANCE W78x and other WDS-compliant devices. These are use d to create a wireless backbone or to connect an individual SCALANCE W78x to a network that cannot be connected directly to the cable infrastructure due to its location.
Page 18 Basic Information on Wireless LAN Communication Redundant Wireless LAN (RWlan) RWlan allows a redundant, wireless connection between two SCALANCE W788- 2xx devices (W788-2PRO or W788 -2RR). This is used to set up a redundant wireless backbone that cannot be implemented as a wired network due to its location but nevertheless has high demands in terms of availability.
