28.1 Introduction
Wireless communication is increasingly used in many industrial automation applications, which have
many differing requirements []. he main automation domains are
•
Process automation, typically dealing with continuous processes (e.g., the continuous or
batch processing of liquids)
•
Factory automation, where discrete, stepwise manufacturing dominates (e.g., mounting
a product from many different parts)
Focusing on discrete manufacturing, again different application levels exist (see Figure .).
Consequently, there is a need for different wireless implementations to cover differing applications
