7 Trend towards higher bandwidths Evolution of the IEEE Standards from abg to IEEE n Page

IEEE 802.11n vs. IEEE 802.11abg Multiple In Multiple Out vs.

Here the receiver compares the quality of the signals received via different paths and uses only the best one.

MIMO: Three transmitted signals, three antennas that transmit - propagation is deliberately via different paths.

8 IEEE n vs. IEEE abg Multiple In Multiple Out vs. Single In Single Out SISO: One transmitted signal, one antenna that transmits - propagation of the signal by reflections. Here the receiver compares the quality of the signals received via different paths and uses only the best one. The other signals are discarded. MIMO: Three transmitted signals, three antennas that transmit - propagation is deliberately via different paths. Here, the signals received via different paths are added correctly according to phase with the overall result of an amplified signal Multiple In Multiple Out (MIMO) allows a higher bandwidth and greater reliability than Single In Single Out (SISO). The bandwidth and reliability grow due to the active use of several antennas. Page

10 What is the "industrial" application for WLAN? controller e.g. cyclic process data transmission e.g. mobile service connections e.g. connection of existing fieldbus systems mobile I/O (sensor/actuator) Industrial applications for open and closed loop control of facilities require deterministic behavior for cyclic communication and fast reactions!

Which media access is suitable for the automation? The deterministic Point Coordination Function (PCF) is suitable for real-time application in the automation.

11 Which media access is suitable for the automation? The deterministic Point Coordination Function (PCF) is suitable for real-time application in the automation. Advantages and Disadvantages of PCF: + Real-time capability, devices do not starve + Fast roaming possible (RR) + Not widespread, low risk of hacker-attacks - Low bandwidth - Low resistances to interferences from neighboured WLANs Standard WLAN with PCF does provide deterministic and is suitable for real-time applications in the automation, because of that.

12 ipcf: polling method with a flexible data rate 1 Flexible data rate: If a large area needs to be covered (e.g. use of omnidirectional antennas), the clients can drop back to 6 Mbps or lower. Advantage / disadvantage: Large range / less real-time performance 2 Poll Page

16 Packet delay ipcf: Roaming methods compared In conjunction with a stable wireless link using RCoax cable, ipcf allows roaming by maintaining deterministic data traffic; ipcf also allows roaming in a much shorter time than non-ipcf systems (for this reason, devices capable of ipcf are often known as "rapid roaming" devices) Roaming with ipcf in 50 ms is almost 100 x faster than the standard method!
