There is more to it. As I understand it (and please, correct me where I'm wrong, internet) as the frequency goes up, the range and ability to penetrate walls goes down. Each generation uses more spectrums, more ranges. So 5G is neat because it's got low frequencies with long-range towers in rural areas, but also high frequency short-range 'towers' in urban areas. This means instead of way too many people trying to share a limited spectrum over a huge area (IE: low frequency in the city), you can have short-range high frequency 'towers' every few hundred meters in a city. But now they're coming for our wifi routers, demanding that spectrum too. And that's kind of bullshit.
