Summary:

Among the many books published on 3G and cellular telecommunications, this introduction stands out due to its broad coverage of the subject and straightforward explanations of the principles and applications. Writing as an engineer for engineers, Ian Poole provides a systems-level view of the fundamentals that will enhance the understanding of engineers and marketing staff working in this fast-paced field. Equally, the book helps technicians, equipment manufacturers and students, to gain a working knowledge of the applications and technologies involved in cellular communications equipment and networks.

The book focuses on the latest 2G, 2.5G and 3G technologies, including GSM (with GPRS and EDGE), NA-TDMA, cdmaOne (IS-95), CDMA2000 and UMTS (W-CDMA), with material on developing areas such as HSDPA. The fundamentals of radio propagation, modulation and cellular basics are also covered in a way that will give readers a real grasp of how cellular communications systems and equipment work.
