Smart Meters go hand in hand with 5G. They are designed to eventually work together interacting with items on the inside of the home and outside more generally.
I have listed countries separately notably USA and UK because USA are more advanced in their roll out than we are here in UK. Lessons from USA can be learned.
Your best bet is to dive in and follow a trail but if you have a key word such as the name of a sub topic or person then come to the page and use ctrl and F to word search. If you are unsure then put the search term in the google search box and it will tell you on what page the item appears.
