The linked website is just the home page of a news site. That's not a good place to start. Care to link relevant articles, for those like me that would like to know more about 5G/6G and your issues with this post?

3G4G Blog [1] is another source if you want technical details, rather than slightly dump down, prosumer but accurate news source ( Lightreading ), Or simply read summary of 3GPP Rel, they are available as white paper on Qualcomm, Nokia and Ericsson's site. The technical case is that 5G network dont have a capacity problem. If you go and ask Three, EE, Verizon ( Ok may be not Verizon ) or Ericsson's engineers. Massive MIMO provides plenty of headrooms for current 5G, 5.5G / 5G Advance, even in places with high population density like Hong Kong. We also have plenty of re-farming to do to increase capacity. ( Re-farming means converting spectrum currently used by 2G - 4G to 5G. ) The problem is cost per capacity. Whether the MNOs are willing to spend more so their user get higher speed during congested period. And the simple answer right now is no. ( Before anyone thinks MNOs doesn't want to upgrade, it is simply they dont want to upgrade so you get 100Mbps instead of 10Mbps during congested hours. If it is below certain level they still do, assuming there is a competitive advantage. ) And unlike 3G to 4G period where you have both the market and Apple pushing MNOs to upgrade, 4G to 5G reaches a point many users are questioning whether it is worth while to pay more, at least initially. And results so far has not been satisfactory, from MNOs perspective. That is partly because they were over hyped, financial projection were too optimistic, COVID, and they completely neglect new market they have enjoyed such as 5G to Home broadband. It is in their interest to downplay this to both shareholders, ( after they have hyped it up ) and to Ericsson so they will not be paying more on hardware upgrades. At the same time it is in Ericsson's interest to show there is a need to upgrade, not just because of capacity improvement but reducing MNO's OPEX. There were also a lot of talks about reducing complexity as one of the selling point in 6G. Especially from Qualcomm ( Yes, the infamous and top hated company on HN actually do a lot of R&D ) Which is partly true because 5G is an extreme complex beast. But it is also another word for more integration between layers and components which means potential increase of revenue for certain vendors. And I am intentionally ignoring all the politics, both between vendors and national level.
