This is Still Not a Book for Scientists!
This book is intended for RF planners, to serve as a practical tool in their daily work designing indoor radio distribution systems.
Based on feedback from readers of the first edition it was clear to me that I needed to add more material and in depth description of the basics of indoor systems based on using repeaters; this has grown into a new Section 4.7.
There was also a strong demand to add more detail and dedicate a full chapter to radio planning in tunnels, for both rail and road tunnels; and redundancy principles in the design focus for solving the challenge of handover zones. An entire Chapter 11 is now dedicated to tunnel radio planning.
Also, although one could argue that this actually belongs in a book about indoor radio planning, I have added the relatively new and exciting option of designing and implementing outdoor DAS. The fact is that this outdoor DAS is implemented primarily to provide indoor coverage - so yes I do think that it is important to include it in this edition, in Chapter 12.
Obviously LTE was the hot topic as I was writing the manuscript; I have added the basics on LTE, MIMO and how to implement LTE inside buildings. Naturally I cannot include all of the deep insight into LTE — for that please refer to  and . At this point only a few deployments of LTE indoors have been carried out and these by vendors — understandably I do not want to disclose all of their secrets and results. However, I have tried to ...
