I can't be the only one seeing this, so if this is old, let me know and I'll delete. Also, I'm glossing over a lot of technical details for the sake of clarity. I or others can answer them in the comments.
Short and sweet: 5G technology has been mocked as a tech solution looking for a problem. The problem is the massive data flood coming from the clot shots.
3G brought internet, better txting, etc. 4G brough bandwidth for multimedia, and streaming, better data throughput.
5G brings a massive increase to volume of devices and bandwidth, but to what end? 4k video? 8k video? Nope, the reality: biometrics and control.
With a high bandwidth frequency you drop range substantially; we're no longer talking miles, we're talking city blocks...and only a couple/few of those.
So best excuse from legacy media/trade rags for this that I've heard is ...smart cars???
Yeah no. How about smart people? As in, we suspected nanotech being in the clot shots, we had some evidence, now we have confirmation coming in from around the world. 5G is being focused on the cities, 80-90% of the population.
Conclusion, 5G is the solution to how you control a population, infused with nanotech with 24/7 live monitoring & control of vitals for billions of people,starting with the population centers.
Internet of Things is a big "benefit" as well. As always, benefit for who? It's really about more control. Control over all devices and appliances, active and passive. And it's about monitoring. Monitoring your possessions, your power usage, and your routines (hmm, beer leaves refrigerator around 10pm most Wednesday nights).
