5G is less about just faster network anyways. The goal as far as I understand is to use something like gre bonding to achieve some support for transparent handoff between base station and home network. So in theory if you are in your own wifi the network should not need to talk to your phone.

Would this transparent handoff work for just calls, or for data as well? I'd love to see a solution to the wifi to 4g data handoff issues I run into.

Multipath TCP is a solution to this, Apple has it in iOS. But adoption is really low.

There are also some unsolved challenges with Multipath TCP, at least last time I studied it in 2014/2015.

For example, when multiple good links are available, Multipath TCP will tend to flip flap between them rather than stabilise on one or the other. You can also get massive reordering which will tend to throw off the congestion control algorithm, but I believe that issue has since been resolved. Good chance are there are some other issues that make MPTCP not quite suitable for widespread use right now.

How is this different from WiFi Calling?

Hopefully it improves over that technology... I regularly get dropped calls switching from wifi to LTE networks, especially if I spend any amount of time on the edge of my wifi network (like if I take the call inside the house and then walk to my garage).
