From what I understand, 5G was first about increased capacity. Increased speed was a secondary point. It optimizes how multiple users can share the same bands, and adds use of higher frequency bands that don't propogate as far. So for very high congestion areas, they can deploy smaller cells and which each can maintain higher speeds per user. I think the "faster" part was just marketing to get users to buy into the new technology. I mean I think that was the intent. Something about the implementation needs tuning though.

Not apologizing for carriers, some are really on the edge of lying to consumers, but you have to separate the 2 parts that make 5G different from 4G.

1. Higher frequencies: means higher throughput but also shorter range (you can literally block that signal with your hand). Only works if your phone supports these higher frequency bands, you have to be in areas where the carrier has deployed cells supporting those, and you have to be close enough.
2. Increased efficiency: mostly affects carriers, you likely won't notice the difference. Basically means, areas that were congested before with LTE will now see less congestion.

I found most 5G ads infuriating. If you know the tech, you understand whats going on and how they aren't telling the complete story. If you don't know the tech, you'll think, "Yay, higher speeds." Nope...

that technology doesn't even make sense

It ain't just your country... 5g speeds marketing was total bullshit.

So if that was the lie... Why did they shill it so hard?
