In this article, we will talk about the latency in 5G networks. For all applications and solutions related to the topic of (energy) network control, of course it would be very interesting to implement control scenarios with the lowest possible latency. As it will become clear from the article, here there are several aspects to consider:

  • The transmission path between base station and end device.
  • The connection of the base station to the provider network.
  • The connection between APN and Private Cloud.
  • The reaction time of the corresponding control systems.

The first point is very interesting for the systems of the energy industry. Currently, everyone keeps talking about the 5G expansion on the highways, and in some cases rail lines and federal highways are also considered. Across the country, the expansion will take a relatively long time, and in some parts, it might never take place. The current business models of mobile network providers are focused on a broad spectrum, not on specific areas. By implication, this means that many energy systems will be connected to 5G only at a late stage and with poor reception, which will cause the latency on the transmission path to increase considerably.

The fourth point, the reaction time of the control systems, will most likely play a significant influence on many processes. Current solutions are often not designed for the „genuine real time“, which also leads to a corresponding slow regulation. If you want to take advantage of the new communication technologies, some adjustments might be necessary.

With current measurements performed with our measuring device TMate Field, we are noticing the following end-to-end signal propagation times:

  • GSM: 180 to 320ms
  • UMTS: 100 to 210ms
  • LTE: 90 to 170ms

This means that we are already finding ourselves in the range with which it would be possible to ensure regulation several times per second. For many application, this is quite enough, we should now begin to align the corresponding processes and uses to the existing possibilities. In this way, one can learn quite a lot and thus can optimally prepare for the new technologies, such as 5G.
