Weird, there was a huge hubub in german tech news at that time but now i only find hints and references, like how secret services were part of the boards, etc., while englisch terms search only spits garbage.
Well, here's about weaknesses in 5G, like downgrade & stingray attaks etc.
What is the actual benefit of 5g besides draining phone battery faster than LTE?
Midband 5G seriously outperforms LTE in my experience. And as radios have matured battery drain has gotten significantly better (which is exactly what happened with LTE radios when we all left HSPA+ behind).
When I had an older 5G phone without midband signal and an early radio, I just left the 5G off. But now I get annoyed if I only have LTE.
