Why 5G instead of WiFi for that scenario?
I think the idea is that the want to replace the cables rather (i.e. not centralized around a WiFi network). 5G is a bit faster too (apparently, not my area of expertise)
As we have SCPI and the like already available over ethernet, I'd have a hard time with throwing an intentional radiator inside my measurement gear. I have enough noise sources to deal with.
Many manufacturer demos tend to be soma variant of that: ie. replacing LXI or some kind of RT-ish fieldbus with 5G. I somehow fail to see any point in making such things wireless.

I think the idea is that they have identified it as an area where they can make productivity gains. If the throughput is there it has obvious in-the-field applications i.e. Who actually enjoys fucking around with cables before you even wire up the DUT - if you want to automatically (say) measure the efficiency of a power supply over some parameter you have to do it by hand (SCPI takes too much time)
The idea is that with 5G you can combine your function generate with your oscilloscope to form a basic network analyser with the data travelling wireless between themselves and your computer. The throughput is high enough, and there wouldn't be any wires.
