So is the difference between 2g, 3g, 4g and 5g that they use different channels/frequencies, different communication protocols, or both?
There's also changing from circuit to packet switching, which also drastically changes how the handover process works.
tl;Dr - handover in 5G is buggy and barely works. The whole thing of switching from one service area to another in the middle of a call is held together by hopes and dreams.
