Korea's continuing lead in speed

OpenSignal is out with a new report that compares smart phone user experiences across 73 countries.   As shown in the graphic at left (click for a full size version), South Korea continues to have the world's fastest mobile networks, as measured by both average upload and download speed using a high tier smartphone.
In making such cross-country comparisons it is well to keep in mind that these are averages and don't represent the user experience in any particular part of the nation.   The local press in Korea these days is full of reports about consumer disappointment with the actual speeds they experience with new 5G phones.  One reason is that the buildout for 5G networks is concentrated initially in the nation's larger cities.  Even in urban area, signal strength inside buildings is a challenge that requires additional network infrastructure.  Things will get better, but it will take time. The project to complete Korea's 5G networks will go on for several years.
