Z o.o. We would like to acknowledge the help of all the people involved in this project. Without their support, this book would not have become a reality. Dear Readers, The book that you are holding now in your hands is the third part of Nokia Book series published in the European Software and Engineering Center in Wroclaw. Traditionally, our specialists have given their contribution. They have written about the real-life case studies which are described in the following pages. “The Future of Telecommunication is Happening Now. Check How the Experts Do It” shows practical dimension of advanced telecommunication technologies and System Engineering threads. Our writers, being at the same time developers, testers, researchers, and engineers in general, did not overlook the topic of professional software development. Taking into consideration the reference to the title of the book we have written, its content extensively covers spectrum of prototyping, creating, and developing new technologies like 5G. The readers curious about the new age of technology will also find several significant articles that deal with Internet of Things, and the future face of Internet. I sincerely recommend this publication to all enthusiasts of telecommunication, including those readers who encountered previous editions of Nokia Book. I am sure they will not be let down by this part. I would also like to thank the authors for their outstanding contribu- tion and hard work.

Advanced Telecommunication Technologies Today we are at the verge of bringing into life the 5th generation The abundant set of requirements pushes 5G platforms towards (5G) of radio systems. In case of 5G, stronger than ever before, the flexible and scalable solutions. Furthermore, some of the require- defined performance targets push for innovative implementation ments force a redefinition of the previously used implementation approaches. This paper outlines some of the main challenges of 5G technologies and practices. As a result, the 5G development relies prototyping, and the main innovations done today in this area. more on hardware (HW) prototyping than the previous generations 5G Prototyping: of cellular systems. 1.
