you can read them at this link), I've long been concerned with the speed of digital networks in general and how fast Korea's networks are in comparison with other countries around the world. Given the multiple organizations that measure internet speed and the many different methods they use, placing Korea in context compared with other countries can sometimes be very confusing. The purpose of this post is not to solve that problem, but rather to call attention to OpenSignal, a relatively new (founded in 2010) company that specializes in mapping wireless coverage and speeds. One strength of their measure is that it comes from users of their app all around the world and therefore reflects internet download speeds in actual usage situations.
Better yet, go to the online Open Signal report and see data for each of the countries in the chart by hovering over the dots.
