What we do?

OpenSignal uses real-world, on-device measurements collected from our apps to offer operators a suite of analytics solutions that provide competitive intelligence and identify revenue enhancement opportunities.

Our data provides increased transparency in the wireless industry by publishing reports on the quality of mobile networks worldwide. We offer independent brand endorsement based on our OpenSignal Awards, which are announced in every report.

How we do it?

OpenSignal data is anonymously collected from consumer smartphones.

Our crowdsourced data is representative of conditions of normal usage from all the places that people go and use their devices, both indoors and outdoors.

OpenSignal conducts end-to-end tests to the same server locations that users connect to on a daily basis when using their mobile data and internet services (e.g. Google, Amazon, etc). This means that our measurements for speed and latency closely reflect a user’s typical everyday experience.
