“To become the global authority on wireless networks” is UK startup OpenSignal’s mission statement. The team of Oxford physics graduates are certainly on the right path having mapped 2G, 3G and 4G network coverage in 200 countries over 800 networks.
Their great network coverage map for the UK, found here is perfect for choosing your next mobile network operator. The data is gathered from their iPhone and android app users and provides in-depth information about specific area coverage, network reliability, download/upload speeds. Enter your postcode in the form and the google maps overlay will show you the best network coverage in your specific area.
OpenSignal is continuing the trend of crowdsourcing ‘big data’ and allowing access to previously unavailable information, helping to validate often inaccurate maps provided by the carriers themselves.
