Each digital mobile generation has produced new use cases and capabilities, as illustrated by Siemens in relation to industrial networks. The range of use cases for industrial networks was originally nil to nonexistent in the analog era.
2G networks added the ability to communicate without wires to sensors or machines and supported remote monitoring and control.
Video surveillance was among the advances for 3G networks. 4G added robust mobile internet capabilities and untethered devices for in-the-field operations. Also, wireless local access was feasible.
The suggestion for 5G is that use cases will multiply as a shift to edge computing in place of remote cloud computing is possible and useful for some applications. Support for autonomous machines is one example; on-the-spot analysis of process data will allow rapid local adjustment of machine parameters.
Private cellular networks that operate as a primary local area network are another expected development.
What remains to be seen is the extent to which connectivity providers will have roles that extend beyond public network access. In other words, what additional value can be provided in the systems integration, edge computing or internet of things areas?
