Communicating machines

The beginnings of the technology date back to the 1920s. At that time, M2M communication was used in telemetry. Weather balloons sent their data via radio waves to data processing systems for evaluation. With the advent of more and more new technologies and telecommunication networks, most recently 5G, the possibilities of M2M communication are astronomically expanding. Today, intelligently communicating machines – smart or intelligent devices – increasingly permeate all levels of human life: from the coordination of container ships to the fully automated smart factory to the smart home controlled via smartphone. M2M communication thus forms the basis for the so-called IoT – the Internet of Things.

A universe of things

What all M2M systems have in common is that they connect data endpoints to a central data integration point, a controlling server, where the data is evaluated and reactions are initiated. The result is a web of interconnected and interacting end devices called the Internet of Things. The IoT is not only the future, but already the present. Even in simple online shopping, automated requests and responses are constantly exchanged between client and server – and in the subsequent logistics, an order can be tracked precisely on the delivery route thanks to M2M. It is no coincidence that logistics is also at the forefront of current IoT trends. The technology has long since become indispensable in fleet management.

The IoT promises far-reaching revolutions, especially in the medical field. Doctor visits for standard check-ups could soon be a thing of the past. There are already numerous wearables for monitoring vital functions. The trend is that in the future, doctors will be able to monitor the health of their patients in real time from a distance with the help of such and similar remote diagnostic systems.

In addition, the IoT holds changes in store for the mobility sector in particular, where far-reaching changes in the architecture of the IoT are becoming visible.

Down to earth

For a long time, the consensus was that every “thing” in the IoT could only communicate via an Internet-based cloud, but a paradigm shift has long been emerging for reasons of efficiency and feasibility. The magic word is “fog” or “edge” computing. It’s all about bringing data processing closer to the point of action. The goal is to make the systems “at the edge” smarter in order to enable their direct communication with each other.

This practically means that an intermediate layer is installed between the application layer and the cloud. While the cloud floats somewhere far away in the data sky, the fog lies in a sense on the ground, referring to the immediate environment of operations. For example, the components of a smart factory form a fog and communicate directly with each other instead of first sending the data via the cloud. The fog can encompass the entire field level of the smart factory.

As indicated, edge computing is currently being used in a particularly revolutionary way in the field of autonomous driving. Here, the technology ensures that vehicles can communicate directly with traffic signs or with each other without detouring via the cloud. The result of these experiments will be completely driverless, autonomous mobility in just a few years.

    Streamlining software development: The journey from multiple to unified requirements management tools

    Productivity in software development is slowed down by managing specifications across various requirements management (RM) tools. Although moving to a single, updated RM tool involves an upfront investment, the long-term benefits are considerable. These include increased process efficiency, enhanced collaboration, superior traceability, improved software specification quality, cost reductions, scalability and better integration with other RM tools, among others.

    Recognising trends: An insight into regression analysis

    Data plays a very important role in every area of a company. When it comes to data, a distinction is made primarily between operational data and dispositive data. Operational data play an important role, especially in day-to-day business. However, they are not nearly as relevant as dispositive data. This is because these data are collected over a longer period of time and provide an initial insight into the history or the past.

    Why do we need digital transformation for medical devices?

    For hospitals, it is not up for discussion as to whether they want to digitalise. The increasing age of the population in western countries and the progressive shortage of medical professionals mean that without digitalisation, the healthcare system will not be able to provide the quality that patients want in the future.
