It is divided into two sections to differentiate between the two technologies' characteristics. The authors systematically explain the design principles and functions of LTE radio protocols during the development of mobile handsets. The book also provides essential knowledge on the interaction between mobile networks and mobile handsets.* Among the first publications based on the 3GPP R10 specifications, which introduces LTE-A* Beginning with an overview of LTE, topics covered include: Idle Mode Procedure; Packet Data Convergence Protocol and Public Warning Systems* Presents the LTE radio interface protocol layers in a readable manner, to enhance the material in the standards publications* From an expert author team who have been directly working on the 3GPP standardsIt is targeted at professionals working or intending to work in the area and can also serve as supplementary reading material for students who need to know how theory on the most extensively used mobile radio interface today is put into practice Zusammenfassung This book offers a unique focus on radio protocols for LTE and LTE-Advanced, covering LTE Layer 2/3 radio protocols as well as new features including LTE-Advanced. From an expert author team directly involved in the 3GPP standards, the book is divided into two sections to differentiate between the two technologies.
