> Stand Alone 5G without relaying on 4G Network Back End What's the difference in the backends? Is it just a question of bandwidth, or is there something more?

Different signalling, better privacy/security (resistance to IMSI catchers), lower latency. It's not a ton better in bandwidth for sub-6ghz but the latency improvement is noticeable.

  I still use 3G intentionally until it is sunset or disconnected. It uses less battery power than LTE, and comes with the nice advantage of that it doesn't support alerts. The latter is an issue because in Canada, the absolute morons who made the decision, decided that all alerts, every last one, are to be sent at the level of Presidential. So, this means an amber alert for some kid who is with one of their parents 500+ miles away blasts through. So people are forced to do complicated stuff like rip out the alert module through the terminal, or set up some sort of schedule where the phone is airplane mode or turned off at night, etc. Too much hassle, 3G is easier. And 3G does use less power. LTE is faster with lower latency but beyond that.. I don't have VoLTE either because the provider is being cheap with my cheap plan.. so why bother. 5G will have lots of battery consumption if the example of LTE is any indication, and no user-facing improvements that I am aware of. Real ones, not theoretical. Wireless data prices are very high here. Nobody is going to use 5G for an internet connection.

The difference is quite large. The architecture for the 5g backend was made to allow for easy virtualization and scaling capacity up and down. Hence telcos don't need to buy a very specific subscriber management box that is special made and needs to handle peak usage. Instead you can buy or rent commodity hardware, and usually run much less hardware because you can scale up as required. Check out the diagram in this article: https://www.geeksforgeeks.org/5g-network-architecture/ https://www.geeksforgeeks.org/5g-network-architecture/ Note how little space is given to the cell towers.
