About OpenSignal

When we founded OpenSignal 7 years ago, we had a very specific goal in mind. We sought an alternative to the old way of measuring mobile network performance. Instead of packing a car full of test gear and then driving around searching for signals, we decided to focus on the consumer. We felt what mattered most to consumers were the actual speeds and availability they experienced on their phones, not some abstract representation of network performance based on test equipment. Using cutting-edge crowdsourcing techniques and rigorous scientific analysis, we developed and improved a testing methodology that we are extremely proud of. What’s more, operators, equipment makers and regulators around the world have validated that methodology by relying on OpenSignal data to make key business and policy decisions.

Today, OpenSignal is the global standard for mobile experience trusted by consumers, and industry stakeholders. We offer a modern and proven way to measure mobile network performance.
