However, TRAI’s latest speed test results claimed that Jio is the fastest operator with an average speed of 16 Mbps, while Airtel’s speed was just at around 7.66 Mbps. A recent Ookla sponsored report also said that Airtel was the fastest operator, but Jio had challenged these claims with the advertising regulator ASCI.
The huge disparity between these reports is due the sample size or number of users/devices surveyed. Open Signal’s latest report claims to have collected data from 93,464 users with more than 1 billion data points. TRAI’s speed results depend upon the number of users performing speed tests using the TRAI MySpeed app. As of now, the app has over 1 million downloads on Google Play. Ookla’s speed test results also depend upon individual user tests, but the company did not mention the sample size when it put out the report.
