In this presentation, the new telecommunications technologies are discussed especially from reliability point of view. After LTE/4G, some further improvements are expected, including 5G and Internet of Things (IoT). The increased data speed enables further improvements in conventional applications, as well as, provides some totally new opportunities e.g. in the area of health monitoring and Machine-to-Machine (M2M) communications.

In order to guarantee faultless operation even in safety-critical applications, like autonomous driving, one has to take care that both hardware (HW) and software (SW) operate as expected. New technology provides both improvements – e.g. in terms of increased analytics capabilities – and challenges as the complexity of systems is increasing. Big data analytics enables health checks both for equipment and human beings. This is also an area of increasing business potential.

Another trend in the telecommunications industry is so-called telco cloud. This means – that hardware that has traditionally been dedicated to a certain network element (NE) – can, and in most cases, will in the future be replaced by servers capable of running any NE functionality.

The development in the telecom industry sets some new requirements both for the competences and the tools. Although deep understanding of HW remains the basic requirement for reliability engineers, the need to understand SW and system-level reliability is increasing. This has some profound impacts on tools and methods that are used in reliability prediction, testing, and verification. Thanks to big data analytics, moving from failure detection to failure prevention is finally becoming realism.


Dr. Olli Salmela received his M.Sc. (E.E.), Licentiate of Technology and Doctor of Technology degrees from Helsinki University of Technology 1992, 1994, and 2005 respectively. He is currently working at Nokia as a Senior Specialist and is the concept owner of Design for Reliability. His research interests include reliability testing, adaptation of new component technologies, and modeling of complex systems, including big data analytics. Dr. Salmela has authored or co-authored more than 30 refereed journal and conference papers. He is the co-author of "Reliability of Microtechnology - Interconnects, Devices and Systems" published by Springer. Dr. Salmela is an adjunct professor at University of Oulu and at Aalto University in Espoo. He holds thirteen patents. Dr. Salmela is a senior member of IEEE and a member of SMTA.
