Today, Mr. Xiaozao recommends a good book to everyone - "5G System View: The Evolution Road from R15 to R18" .
In this book, the author comprehensively sorts out the entire development of communication technology from wired to wireless, from 1G to 5G, and gives the history behind the transformation of mobile communication technology and the potential driving force behind its evolution.
In each chapter of this book, the technology is summarized and sorted out, and the technology is explained end-to-end across protocol layers and fields, aiming to help readers establish a system concept and deeply understand the essence of technology and trends.
The book contains more than 200 pictures and more than 100 tables. Most of these pictures and tables are drawn by the author according to the technical principles, which are very helpful for readers to understand the technical principles more thoroughly.
In addition, the book also contains more than 60 RRC ASN.1 code fragments, the purpose is to let readers understand the protocol implementation more intuitively, understand the product implementation, the meaning and value of each protocol parameter.
The author of this book is an outstanding scholar who has been fighting in the front line of 3GPP standards for a long time. He has deeply participated in the whole process of global 5G standard formulation, made important contributions to the development of 5G, and is also the backbone of my country's communication standardization.
