A method and apparatus for operating a femto-cell base station are disclosed. The femto-cell base station is configured to provide coverage to a User Equipment by connecting it to a core telecommunications network using a first frequency belonging to a first radio access technology. The method includes detecting that a fixed network connection of a femto-cell base station is not operative, and, in response to such failure, scanning frequencies in a second radio access technology available to a wireless network interface of the femto-cell base station, said second radio access technology being different than the first radio access technology. If there is any frequency available in said second radio access technology, said frequency in said second radio access technology is established as the operational frequency of a cellular wireless network connection established by the wireless network interface.
