5G and Satellite Spectrum, Standards, and Scale

5G and Satellite Spectrum, Standards, and Scale

Author: Geoff Varrall Format: Hardback Release Date: 30/06/2018

This title is written as a direct follow on to Varrall's 2016 book. It provides an update on 3GPP Release 16 and 17 and the related `New Radio' physical layer specifications. It also studies the implications for World Radio Congress 2019 and related 5G and satellite standards work and discusses the likely impact on the future enterprise value of satellite and 5G operators and their associated supply chains. The satellite industry is entering a golden age of innovation which is having a profound impact on the delivery economics of connectivity from space. Over the past two years there has been a remarkable technical and commercial transformation in the satellite industry, with new service models emerging both from existing established geostationary orbit (GSO) operators to 'NEWLEO' operators such as LEOSAT. Many 5G vertical market use cases could potentially now be served more efficiently from space, but several regulatory and competitive positioning issues need to be resolved before these techniques can be deployed and trusted universally. This book documents these techniques and the associated interference modelling and explores the evolving business and financial and commercial implications of this transformation process. It also captures the emerging focus on discrete vertical markets and their specific physical layer and upper layer protocol and performance requirements.

5G Spectrum and Standards

5G Spectrum and Standards

Author: Geoff Varrall Format: Hardback Release Date: 30/06/2016

Readers find contemporary examples of millimeter band radio hardware including 60 GHz and V band and E Band point to point radio. This book demonstrates the profound progress with 4G radio signal processing and RF hardware to reveal its potential applicability to 5G radio systems. It shows how 5G systems are capable of delivering data rates that are ten to one hundred times faster than 4G systems. Developments in spatial processing and beam forming in local area radio networks are presented and the challenge of scaling these systems to wide area radio is explored. This book reviews military and space radio and automotive radar innovation with direct relevance to 5G radio design.

Making Telecoms Work From Technical Innovation to Commercial Success

Making Telecoms Work From Technical Innovation to Commercial Success

Author: Geoff Varrall Format: Hardback Release Date: 06/01/2012

Bridging the industry divide between the technical expertise of engineers and the aims of market and business planners, Making Telecoms Work provides a basis for more effective interdisciplinary analysis of technology, engineering, market and business investment risk and opportunity. Since fixed and mobile broadband has become a dominant deliverable, multiple areas of transition and transformation have occurred; the book places these changes in the context of the political, social and economic dynamics of the global telecommunications industry. Drawing on 25 years of participative experience in the mobile phone and telecommunications industry, the author closely analyses the materials, components and devices that have had a transformative impact. By presenting detailed case studies of materials innovation, such as those shown at success story Apple, the book shows how the collaboration of technological imagination with business knowledge will shape the industry s future. * Makes a link between the technical aspects and the business practice of the telecoms industry, highlighting the commercial and economic significance of new developments * Gives a historical analysis of past successes and failures in order to identify future competitive advantage opportunities * Supplies detailed case studies of supply chain disconnects and the impact these have on industry risk and profitability * Brings together technological detail with analysis of what is and is not commercially important, from the implications of energy and environmental networks to the technical details of wireless network hardware.

Data Over Radio Data and Digital Processing Techniques in Mobile and Cellular Radio

Data Over Radio Data and Digital Processing Techniques in Mobile and Cellular Radio

Author: Geoff Varrall, Roger Belcher Format: Paperback / softback Release Date: 25/02/1998

A complete guide to radio data transmission Data Over Radio: Data and Digital Processing Techniques in Mobile and Cellular Radio is a comprehensive guide to data transmission and processing using radio waves. Covering both hardware and software technology, this book provides guidance on devices, circuits, coding, wavelengths and more, with specific advice for applications including trunked systems, analog cellular, two-way radio, and dedicated public networks. Extensive discussion on GSM and digital cellular in Europe, Japan, and the U.S. provides application-specific guidance, and information on working with geostationary, low-orbit, and high-elliptical satellites facilitates an understanding of transmission and propagation.
