24.1 Introduction
Wireless communication systems diffused into an ever-increasing number of application areas and
achieved wide popularity. Wireless telephony and cellular systems are now an important part of our
daily lives and wireless local area network (WLAN) technologies become more and more the primary
way to access business and personal data. Two important benefits of wireless technology are key to
this success: the need for cabling is greatly reduced and computers as well as users can be truly mobile.
This saves costs and enables new applications. In factory plants, wireless technology can be used in
several interesting ways [, chap. ]:
