Sina 5G test drive 230Wenzi Long and Qu Ruihao of drove 30 kilometres through the heart of Beijing, often finding signals from the 5,000 5G base stations already installed. They only tested outdoors. On an empty network, 50 metres from the cell, downloads were 1112 Mbps. At 500 metres, the speed went down to 210 Mbps. 

They note, "In the densely populated buildings and thicker walls, the 5G signal is unstable and the speed is unstable."  With ~80% of connections indoors, that brings down the average speed. In Korea, the average download speed is less than 200 Mbps

The most interesting thing in the article is ping times to as low as 13 ms. Milan Milankovich at Ookla told me it has seen other very low readings from China. Given the air latency of 5G today is 8-12 ms, that implies a remarkable backhaul and transit network.

I didn't know China has started building their remarkable Edge network, which will connect over a billion people.
