New 5G protocol vulnerabilities allow location tracking
5G baffles me.  I hear about it from politicians.  I hear about it from telecom companies.  I hear about it from my tech-illiterate dad, who asked me "Does it have 5G?" when I told him I got a new smartphone.But... what is it?  Higher bandwidth?  Lower latency?  Is it the IoT dream, my smart microwave connects to a cell tower instead of my private subnet?  Does it replace my wired home internet connection?And, bonus question - what's the theoretical bandwidth limit per person for, say, a football stadium full of people?  Does this limit improve on 5G vs older specs?  At what point does physics prevent us from having better standardized wireless networks?
