This book presents LTE evolution towards 5G mobile communication and the emergence of new requirements for MBB, MTC and LLC services. As LTE technologies evolve, LTE Advanced Pro dramatically increases cell capacity and user data rates for the MBB unicast service. Such requirements are obtained using full-dimension MIMO, carrier aggregation (on either licensed or unlicensed frequency bands) and dual connectivity. To improve the efficiency of same-content delivery to multiple users, 3GPP proposes a group communications service over LTE and defines mission critical push-to-talk (MCPTT) for dedicated public safety services. Complementary low-cost and low-power modems with enhanced coverage and massive connectivity are emerging. Thus, this book also discusses the need for LTE to support low-rate transmission and high-latency communication for MTC services.

NG-RAN and 5G-NR describes the deployment of 5G NSA (non standalone 5G) and 5G-SA (standalone 5G). 5G-NSA deals with radio access entities. For the 5G-NSA mode, dual MR DC connectivity is based on radio measurements, allowing the master 4G base station MeNB to add or remove a secondary 5G node SgNB.This book describes the architecture of the NG radio access network and the 5G-NR radio interface according to the 3GPP (3rd Generation Partnership Project) specifications. The overall architecture of the NG-RAN, including the NG, Xn and F1 interfaces and their interaction with the radio interface, are also described. The 5G-NR physical layer is mainly connected by implementing antennas, which improves transmission capacity. 5G-SA deals with the 5G Core network.In the 5G-SA model, the mobile is attached to the 5G Core network through NG-RAN. The book explains radio procedure, from switching on a device to establishing a data connection, and how this connection is maintained even if mobility is involved for both 5G-SA and 5G-NSA deployment. NG-RAN and 5G-NR is devoted to the radio access network, but mobile registration, establishment procedures and re-establishment procedures are also explained.

This publication characterizes the environmental burden of disease in the United Arab Emirates (UAE), measured by the excess number of deaths and illnesses in the population due to exposure to environmental hazards. The robust methods used in this risk analysis can be applied to any country or region. This publication documents the systematic, multi-step process used to identify environmental priorities and the detailed methods used to quantify the disease burden attributable to each risk. Based on the results of the burden of disease assessment, the publication summarizes the subsequent steps that are recommended to further reduce the burden of disease resulting from various environmental risk factors.​Authors and ContributorsThis book represents the synthesis of research carried out by a large, interdisciplinary team from several institutions and multiple nations between June 2008 and June 2011.The lead authors are responsible for weaving together the pieces prepared by the team.Nonetheless, this book would not have been possible without major contributions from each team member.The list below shows contributors to each chapter.Following this list are biographies of all of the authors and contributors. Lead Authors                Jacqueline MacDonald Gibson, Frederic J.
