The Reality Check for Private Networks at Hannover Messe
As the largest industrial trade show in the world, the annual Hannover Messe Industry (HMI) is an important seismograph of what is happening within industrial verticals like manufacturing, energy generation, or logistics. In this context, of course, 5G made its appearance at the show once again—after the last in-person addition of the trade fair in 2019 saw the inauguration of the 5G Alliance for Connected Industries and Automation (5G-ACIA) at a specifically dedicated exhibition space, the 5G Arena.
At Hannover Messe 2022, 5G connectivity had a tough reality check. The many discussions with industry experts showed that the 5G hype among industrial manufacturers (especially Small and Medium Enterprises (SMEs)) is over, and the focus now is on much more realistic use cases for the short and medium term. For example, industrial automation vendor Siemens demonstrated transmitting PROFINET via 5G connectivity. Similarly, Phoenix Contact showcased how 5G can be used as a wireless “data pipe” to transmit safety-critical information.
