Review by Marina Ruggieri
This edited book is an interesting effort to provide a coherent framework to the In-Band Full-Duplex (IBFD) approach and its technological developments.
IBFD has a potential in the future of connectivity technologies, even if the challenges that the 5G to 6G transition will pose might be somehow different from those expected only a couple of years ago. The pandemic, in fact, has impressed an unpredicted acceleration to connectivity infrastructures, that have demonstrated to be a trustable ally of Human Beings in troubled waters, and to their vertical application domains. The 5G-to-6G transition might be then faster than expected and strongly driven by the need to strive for sustainability.
From the above viewpoint, this handbook is about a research matter that would need the proper time and opportunity to converge into a commercial framework. In spite of this, the reader will find the book interesting.
The topic is clearly explained and the various contents well organized. In particular, it is admirable the effort of the editor to provide a systemic frame to a matter that is still “scattered”. The use of the Self-Interference Cancellation (SIC) technique tree not only in the introductory chapter, as it would have been obvious, but in all chapters guides the reader to frame the various developments from a system viewpoint and this, in turn, increases the trust in the IBFD technology applicability at system level.
Additional aspects need to be focused in the future for a complete appreciation of the topic: the alignment of the time scale in the various developments in terms of readiness level, the consequent impact on costs and the impact of the IBFD technology on the sustainability level of the connectivity infrastructure.
