[null,null,null,"Sommario/riassunto","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 using a minimum of maths. Writing as an engineer for engineers, Ian Poole provides a systems-level view of the fundamentals that will enhance the understanding of engineers involved working in this fast-paced field. Equally, the book helps students, technicians and equipment manufacturers to gain a working knowledge of the applications and technologies involved in cellular communica"]
