Legends say 5G signals travel FASTER than the speed of light. How else would signals propagate 350 miles into space, another 7000 miles circumferencially around the world, then another 350 miles back down to earth and still be faster than a landline connection?
No need for 5g, it has a crazy amount of power and can harm things if miss used. The range for 4g LTE is plenty fast. We wouldn't be fighting everyone's signal to connect where we want to. Going up to space and traveling through it has nearly no interference. In turn folks like Aus connecting to London servers reduces the amount of potential interference. So instead of driving from California to New York, your flying from Cali to New York.
Pure LAN is the fastest by far, but that still depends on your provider and what you have for speeds. They could cap you and the speeds could be nearly the same. I use Mobile Hotspot and get nearly 30mb/s dls with 4g LTE. Everything runs just fine, it's all latency after that. Which I feel it is mostly effected by range and interferences along the way.
