EETE: There are special networks for this, such as Sigfox.
Steffen: Many services that currently feature proprietary wireless technology will be implemented with 5G in the future. Mass production makes powerful platforms very affordable; proprietary technology is always costly. That is why applications with direct connections between user devices could be better implemented with LTE in the future. The standard already provides for this; but it is not well supported by network operators. The automotive industry is also pushing into this field with car to X (C2X) applications. You need very low latency when security related C2X services come to the point of being able to transmit to their environments, for example when a car reports, "Caution, I'm braking". In this case, the car should not have to first establish a connection with its network operator. The technologies currently under development with 5G would be able to do that. But we will have to wait to see what the business models look like. We expect that more applications will be implemented with 5G technologies than is possible in mobile communications networks today. It remains to be seen, however, how many of these functions will ultimately be available in mobile phones.
From a test and measurement standpoint, it is more of a technology issue. We have to handle bandwidths and latencies and implement what the standardization bodies specify. These are matters of modulation modes and physical levels. The physical layer is being redefined, and we naturally have to
