Book Preface

The last 20 years have witnessed an impressive evolution in global mobile communications from voice-centric 1G/2G services to 3G data services starting in 2001 and 4G mobile broadband starting in 2010. In Japan, NTT DOCOMO launched the world’s first mobile Internet service, “i-mode,” in February 1999 on the PDC-Packet(2G) system, and the service spread widely in Japan in the 3G era. The smartphone was introduced on the 3G system, and its use has spread in the 4G era. The numbers of mobile subscribers and devices have increased rapidly, and data usage has exploded. Data speed has increased from 2.4 kbps in 1993 to 1.2 Gbps in 2019, which is a 500 000-fold increase in just a quarter of a century. I have been lucky to be part of this evolution in NTT DOCOMO and to have seen firsthand such great achievements and also the great challenges the industry has overcome to manage the fast changes. We are now witnessing the beginning of the next major step in the evolution: 5G. We believe that 5G is one of the main pillars for providing value and excitement to customers and opportunities for value co-creation with partners in the 2020s. 5G also brings a number of new challenges the industry must meet in order to fulfill all these promises.

NTT DOCOMO has been one of the world’s leading companies in developing advanced technologies and services for new-generation mobile communication systems including 5G. NTT DOCOMO launched pre-commercial 5G services in September 2019 and will launch fully commercial 5G services by Spring in 2020 for serving customers in Japan and for providing a great spectator experience to consumers during the Tokyo Olympic-Paralympic Games. We have been aggressively pursuing the creation of new services for the 5G era, such as the DOCOMO 5G Open Partner Program, and we believe that many new enterprise services can be created together with a variety of industry partners and that the market size of enterprise services can be expanded drastically utilizing 5G characteristics.

This book provides a combination of 5G specification explanations, performance evaluations, device design aspects, practical deployment considerations, and field experiences that will help to roll out and tune 5G networks. The book has been written by more than 30 experts from multiple companies around the world, including network infrastructure and chipset vendors and mobile operators.

My colleague Takehiro Nakamura has been a key contributor inside NTT DOCOMO and also globally in 5G standardization, development, and early testing. He has nearly 30 years of experience in the field. Harri Holma and Antti Toskala from Nokia Bell Labs bring worldwide knowledge of 5G technology and its details. Harri and Antti have 25 years experience in the industry starting from early days of 3G research.

I believe that you will find this book enjoyable and useful in helping you to enhance your understanding about the potential of 5G technology. I hope that we can witness
together a successful future for 5G technology during the next decade.
