Who gives the best cellular signal in SA?

Gr8signal, a service developed by LucidView that measures mobile network coverage, has started reporting which network is leading in signal strength and coverage in South Africa.

The service gathers data through a mobile app, which only supports Android for the moment, sending through data such as the network and tower information, the location the reading was taken, and the signal strength at that position.

Over the last 3 months almost 900,000 data points were collected, showing that Vodacom seemed to offer the best coverage on average of the places surveyed.

The red network also had the highest recorded coverage and the highest number of towers per square kilometre on average.

Keeping in mind that the service has only been running for a few months, the statistics should not be considered an accurate reflection of the mobile network coverage situation in South Africa.

However, it will be interesting to record the data emerging from gr8signal to compare how the operators’ positions may change over time.

The table below shows how South Africa’s mobile operators stacked up against one another as of February 2013:

Operator Average signal strength Recorded coverage (km²) Average towers per km²
Vodacom -84.01±10.88 10,146 4.13
Cell C -87.35 ±17.03 7,770 3.68
MTN -92.05 ±14.05 5,050 3.61
8ta -93.14 ±11.73 1,072 3.23
