Practical Wireless, Ethernet and TCP/IP Networking

THE WORKSHOP

The use of wireless and Ethernet in industrial and plant floor environments has grown dramatically in the last few years. Industrial users face a wide range of options when designing and implementing plant-level wireless and Ethernet networks.

Great success is being achieved using wireless provided certain ground rules are applied such as ensuring a robust wireless link, correct integration with the wired communications systems and proper data security.

The most important objective of wireless communications networks must be to achieve similar capacities, bandwidths, responsiveness, reliability and availability to that of wire based communications with an emphasis on the unique needs and challenges faced by industrial networks.

This workshop commences with an overview of wireless communications and how radio works, “Wireless Local Area Networks” or WLANs (IEEE 802.11) are then examined. A practical discussion of Ethernet has been added as this is always a key ingredient in a successful wireless implementation strategy.

Ethernet is the obvious choice for industrial control networking worldwide. While the basic structure of Ethernet has not changed much, the faster technologies such as fast Ethernet and gigabit Ethernet have increased the complexity and choices you have available for planning and designing these systems. Finally the all important topic of troubleshooting of wireless and Ethernet networks is examined with a summary of the typical problems you are likely to encounter from a two station network all the way up to a system comprising 30,000 PCs.

This workshop addresses these issues in a clear and practical manner, thus enabling you to apply the technology quickly and effectively in your next project. At the end of the workshop you should have a clear understanding of the choices available to you in designing and implementing your own wireless and associated Ethernet networks.
