This map shows how consistently accessible 4G networks are in each country. Rather than measure geographic coverage, OpenSignal’s availability metric tracks the proportion of time users have access to a particular network. For example if a country has 50% 4G availability, then on average that country’s 4G users can find an LTE signal half of the time.
A high 4G availability can be an indication of good geographic coverage, but the metric tracks more than where users can find an LTE signal on a map. It accounts for indoor connections and times of high congestion when it’s often difficult to get a 4G signal even on high-coverage networks.
For this report was analyzed 17 billion measurements conducted by 500,687 OpenSignal 4G smartphone users between July 1 and Sept. 30.
