Best Mobile Coverage
As part of our mission to improve internet connectivity for everyone we are celebrating mobile & fixed network operators that are providing the best quality of service to their customers.
The SpeedChecker Champion award for Best Mobile Coverage category relies on crowdsourced measurements collected using the methodlogy described below.
Speedchecker has developed a robust and reliable methodology of assessing cellular coverage worldwide. Our data-driven approach is to use billions of cellular measurements conducted by hundreds of millions of mobile devices.Process
Speedchecker’s data analysis process for mobile coverage involves four primary steps: collection, filtering, spatial aggregation, and summarization. The results of that process are used to determine coverage score on a country and operator level.Collection
Millions of cellular measurements are received daily from Android devices around the world.Filtering
Filtering is applied to ensure that only relevant measurements are used:
- Erroneous out-of-range measurements are excluded from datasets
- Measurements executed by inactive devices are excluded
- Measurements with inaccurate location are excluded
Filtered multi-RAT signal measurements collected for last 12 months are grouped into tiles of approximately 1 km2. All tiles where at least one operator service was detected are summed up to form a total country coverage footprint. Average signal strength is calculated per tile per RAT for each operator. Each operator is then assigned with a score per tile depending on average signal strength and particular RAT availability (higher RAT and stronger signal will contribute a higher score).Summarization
Finally, scores from all tiles are summed up per operator. This forms the total operator coverage score. Total operator coverage score is then divided by the total country coverage footprint to produce an overall OPERATOR COVERAGE SCORE.
