Opensignal Korea availability 230The Open Signal data is devastating for 5G. The companies claim over 90% coverage. More than 10,000 participated in Open Signal's 5G tests in May. They only connected to 5G ~15% of the time. The only explanation I can think of is that the indoor performance of Korea's 5G mid-band is awful and much worse than I and many others expected. (Left and below)

I've been asking anyone with data for indoor figures but only getting anecdotes. What I was told was that the mid-band 5G had decent indoor coverage. I should have been much more skeptical in the absence of data. Better phone antennas, improved software for MIMO, and other technologies are coming. 

But if this data proves out, 5G offers much less than almost everyone except Dean Bubley expected.

When the phones connected with 5G, the average speed was over 200 Mbps.

----------

Welcome  Asia is installing hundreds of thousands of 5G radios and adding 5G subs by the tens of millions. The west is far behind. 200,000,000 in 2020

The demand is there, and most of the technology works. Meanwhile, the hype is unreal. Time for reporting closer to the truth.
