Samsung Electronics supplies 53,000 5G base stations for Korean carriers

Korea claimed to be the first country to start 5G but who wanted 5G so fast? The Korean government wanted it. The government set the goal to become the first, then pushed (I would say "ordered") the all three mobile operators to launch 5G, and the three operators launched it at the same time first in the world. In other words, the government artificially made the demands for 5G base stations only for Samsung.
Samsung has grown in this way. It is now the one of the well-kwon companies in the world and this single company earns around 15% of Gross Domestic Product of Korea. Samsung is big enough and can service without being fed by the government. I doubt the government-driven tech development would work forever.
You know what, there is no IPv6 available in Korea yet. Something doesn't sound right to me.

FYI, because of its frequency characteristics, the cover range of a 5G station is much shorter than that of a 4G station, almost one-fourth of 4G. So much more base stations required than 4G.
Base stations in dense cities may be reduced because of the decreased traffic per tower.
However, 5G won't have any significant advantage over 4G in those frequencies other than a little bit improved throughput. The ultimate goal of 5G is to use frequencies above 6GHz, usually around 28GHz (!) in order to have sub-1ms latencies and ultrafast throughput. This requires numerous "small cells" deployed.
I found unbiased sources below. You will find that these articles assumes the frequency above 6GHz should be used.
