Wireless technologies like GSM, UMTS, LTE, Wireless LAN and Bluetooth have
revolutionized the way we communicate by making services like telephony and Internet
access available anytime and from almost anywhere. Today, a great variety of technical
publications offer background information about these technologies but they all fall
short in one way or another. Books covering these technologies usually describe only
one of the systems in detail and are generally too complex as a first introduction. The
Internet is also a good source, but the articles one finds are usually too short and super-
ficial or only deal with a specific mechanism of one of the systems. For this reason, it
was difficult for me to recommend a single publication to students in my telecommunication
classes, which I have been teaching in addition to my work in the wireless telecommunication
industry. This book aims to change this.
