A one-stop reference that offers an accessible guide to an understanding of the enhanced core technologies of 5G

5G Second Phase Explained ? The 3GPP Release 16 Enhancements offers an authoritative and essential guide to the new functionalities of the Release 16 that complement the first phase of the 5G. From the author of 5G Explained comes the next step resource that includes detailed descriptions that provide a clear understanding to the full version of the 5G technologies and their impacts on the Phase 1 networks.

The author?a noted expert on the topic?not only reviews the most up-to-date functionalities of the Release 16 but includes information on the forthcoming Release 17 as well as material on future developments. The book explores the highly unique aspects of the Release 16, which can help technical personnel?s efforts to deliver essential information in a practical way. The two books, 5G Explained and 5G Second Phase Explained, offer a comprehensive understanding of 5G. This important guide:
* Offers a summary of the newest and key features of 5G
* Presents a one-stop reference for an understanding of the core technologies of 5G
* Contains a new book that expands on the author?s 5G Explained
* Puts the focus on security and deployment aspects of 5G enhancements

Written for technical personnel of network operators, network element and user device manufacturers, 5G Second Phase Explained offers guide to an understanding of network deployment and device designing of 5G technologies.
