The industry came up with the moniker "5G" largely for marketing purposes. In many situations and for most users, there will be little difference between 4 and 5G in both good and bad ways: can't get a good 4G signal? 5G probably won't improve matters, either.
Sweden, home of Ericsson, doesn't even feature in the analyst's list of the top 22 nations for 5G.
Why would that surprise anyone? 5G makes most sense in areas with high population density, hardly a problem for Sweden outside the large cities and even there, the density of devices hardly approaches that of east Asia.
