Bøker av Jyrki T. J. (Nokia Siemens Networks) Penttinen

Pioneering outline of the concept which enhances 5G capabilities and will revolutionize the telecommunications industryOpen RAN Explained details the new architectures, functionalities, and interfaces of Open RAN models and explains the standards, principles, and practical aspects the operators need to know to be prepared for the new era. The work describes the challenges and opportunities of modularization and presents scenarios and recommendations for optimal network deployment considering techno-economic aspects. It further summarizes the latest key features and aspects of the Open RAN to provide readers with a single source of information that eases network deployment, device designing, and education of personnel and students interested in advanced mobile communications.Technically, the work references the latest specifications of the O-RAN Alliance and GSMA OP/TIP, complemented by the current 3GPP Release 16 specifications on the network virtualization and spit models for which deployment is expected from 2022-25.Written by an author working at the cutting edge of 5G development in industry, sample topics covered in Open RAN Explained include:* Open RAN architecture, exploring ideas like details of the requirements and challenges of the cloud runtime environment the Open RAN needs for O-Cloud* RAN modularization, covering the role of 4G and 5G, 3GPP split options, O-RAN options, and hardware design* O-RAN use cases, such as traffic steering, QoS and QoE optimization, massive MIMO, network slicing and service level assurance, and V2X handover* Open RAN planning and deployment, regarding Open RAN deployment scenarios, service-based planning aspects, optimization, site strategies, and morePresenting many practical examples to aid in reader comprehension, Open RAN Explained is an essential and accessible resource for operators, equipment manufacturers, service providers, regulators, and educational institutes alike to understand and explore the principles and details of the Open RAN.

Practical Guide Provides Students and Industry Professionals with Latest Information on 5G Mobile NetworksContinuing the tradition established in his previous publications, Jyrki Penttinen offers 5G Explained as a thorough yet concise introduction to recent advancements and growing trends in mobile telecommunications. In this case, Penttinen focuses on the development and employment of 5G mobile networks and, more specifically, the challenges inherent in adjusting to new global standardization requirements and in maintaining a high level of security even as mobile technology expands to new horizons. The text discusses, for example, the Internet of Things (IoT) and how to keep networks reliable and secure when they are constantly accessed by many different devices with varying levels of user involvement and competence.5G Explained is primarily designed for specialists who need rapid acclimation to the possibilities and concerns presented by 5G adoption. Therefore, it assumes some prior knowledge of mobile communications. However, earlier chapters are structured so that even relative newcomers will gain useful information. Other notable features include:* Three modules each consisting of three chapters: Introduction, Technical Network Description and Planning of Security and Deployment* Comprehensive coverage of topics such as technical requirements for 5G, network architecture, radio and core networks and services/applications* Discussion of specific security techniques in addition to common-sense guidelines for planning, deploying, managing and optimizing 5G networks5G Explained offers crucial updates for anyone involved in designing, deploying or working with 5G networks. It should prove a valuable guide for operators, equipment manufacturers and other professionals in mobile equipment engineering and security, network planning and optimization, and mobile application development, or anyone looking to break into these fields.

This book describes the current and most probable future wireless security solutions. The focus is on the technical discussion of existing systems and new trends like Internet of Things (IoT).

Taking a practical approach, Telecommunications Handbook examines the principles and details of all major and modern telecommunications systems currently available to industry and end-users.

DVB-H is the leading global physical layer specification for the transmission of broadcast services to battery-powered handheld receivers, such as mobile phones and PDAs. The DVB-H Handbook describes the principles and details of the DVB-H system, giving a complete picture of its background, functioning, planning and optimization.
