As Ericsson's new CTO since July 1st, I am excited to take over the role of publisher of Ericsson Technology Review and continue the excellent work that Ulf Ewaldsson and his predecessors have done since the first article was published 93 years ago. I want to welcome both new and longstanding readers to join us in learning more about the latest findings within Ericsson's Research and Development units.
This month's article is about 5G and New Radio (NR). To meet the complex requirements of use cases that include everything from robotic surgery to virtual reality classrooms and self-driving cars, 5G will encompass both an evolution of today’s 4G (LTE) networks and NR - a new, globally standardized radio access technology. The article provides an overview of the 5G physical layer and its design principles, showing how the flexible and energy-efficient design of 5G NR will enable diverse uses cases in a wide range of frequencies with various deployment options.
