Every year, OpenSignal releases their State of LTE report, showing how LTE has progressed in the world. It shows which countries have the fastest speeds, the best ping time and the best coverage. To no surprise, South Korea actually has the best availability of LTE in the world right now. This shouldn't be a surprise, since they have both Samsung and LG working with carriers to bring in new technology, not to mention it's a fairly small country - but densely populated, so capacity is a big deal. The crown for the fastest speeds actually belongs to Singapore.
When it comes the average speed, the US is actually towards the bottom of the pack, with an average of 13Mbps. That's even lower than the worldwide average of about 17.4Mbps. Of course, Singapore and South Korea lead everyone, with averages over 45Mbps. Now keep in mind that there are likely places in these countries that see much faster speeds, but this is the average. The bottom three in LTE speeds, consist of India, Saudi Arabia and Costa Rica. Which are all emerging markets, so it's not too surprising to see these bringing up the bottom portion of the LTE speeds test.
OpenSignal used data from over half a million different users, and over 17 billion different data points to put together this report. This was all done between July 1st and September 30th of this year. So the data is mostly up-to-date, even though it is now November - let's face it, it takes a bit of time to actually get all this data put into a report to see how LTE stacks up in each country. The US has always been notoriously slow, when it comes to LTE speeds. A big part of that is due to the size of the country, and the number of users on LTE. Which is why carriers have been having issues with capacity lately. The US does have LTE available in about 81% of the country, however. So you're likely to have LTE just about everywhere you go. Of course, that is still pretty far behind the leaders of South Korea with 95% availability and Japan with 92%. You can check out OpenSignal's full report by hitting up the source link below.
