As part of a new project being run by the broadcasting organisation, the UK 3G survey app will record data on 3G network coverage from every device the app is installed on for over a month.
The data will then be sent to Epitiro, the firm that recently helped Ofcom chart mobile broadband speeds across the UK and developed the app on behalf of the BBC, where it will be collated into a map that is searchable by postcode.
The app is free to download from the Android Market now and according to the BBC uses very little bandwidth and the data is anonymised and neither the BBC or Epitiro will store personal details relating to the mobile phone owners that take part in the survey.
"Coverage is the number one issue for consumers," said chief executive of Epitiro, Gavin Johns, according to the BBC.
"Our coverage app will provide the information consumers need to see if 3G services are available and from which mobile operator. As mobile broadband is important to many of us, we hope people volunteer and make the project a success."
