This book is a collection of 10 articles around 5G, framed by an introduction and summary from the editor Jonathan Rodriguez.
More or less every article starts with the same motivation for 5G: mobile traffic will increase 1000times form 2010 to 2020.
Here some findings from the articles:
- 5G is not one radio access technology (RAT). It will be a collection of RATs like small cells, SON, ... (chapter 1)
- Spectral efficiency is about 1 bps/Hz/cell - gains can be achieved with multi-antenna techniques and small cells (chapter 3)
- 5G devices are expected to exploit spectrum opportunities efficiently on the fly (chapter 6)
- new transceivers have to be built with excellent power saving characteristics and tunable RF frontend radio. (chapter 11)
