Many industrial automation applications are designed to be very flexible in order to manufacture products with an increased efficiency. Thus a flexible communication infrastructure is required, leading to a growing demand for wireless networks. Wireless networks fulfill these requirements, because they offer more flexibility, cost reductions and a higher mobility to the automation system as compared to their wired counterparts.Since the communication in future industrial automation systems will be most likely realized by real-time Ethernet protocols like PROFINET, Ethernet/IP, etc., the corresponding wireless technology at the field level has to be suitable and carefully chosen with respect to the application requirements, in terms of both dependable and temporal behavior. Therefore, IEEE 802.11 wireless local area networks (WLANs) are an interesting option, because they were initially designed to be the wireless extension of Ethernet. This chapter describes the IEEE 802.11 family, the current technology and its limitations, and outlines the future enhancements that are currently under specification in the relevant standardization Task Groups.

Abstract

Many industrial automation applications are designed to be very flexible in order to manufacture products with an increased efficiency. Thus a flexible communication infrastructure is required, leading to a growing demand for wireless networks. Wireless networks fulfill these requirements, because they offer more flexibility, cost reductions and a higher mobility to the automation system as compared to their wired counterparts.Since the communication in future industrial automation systems will be most likely realized by real-time Ethernet protocols like PROFINET, Ethernet/IP, etc., the corresponding wireless technology at the field level has to be suitable and carefully chosen with respect to the application requirements, in terms of both dependable and temporal behavior. Therefore, IEEE 802.11 wireless local area networks (WLANs) are an interesting option, because they were initially designed to be the wireless extension of Ethernet. This chapter describes the IEEE 802.11 family, the current technology and its limitations, and outlines the future enhancements that are currently under specification in the relevant standardization Task Groups.
