months of the approval of the Plan. Within six months of the approval, the plan will be amended if appropriate (in view of public resources available) and forwarded to the European Commission for approval, which means that the preliminary condition will be met by November 2016 at the latest.  To provide at least a 1 Gb/s internet connection to all public education and research institutions and other eligible users of the Arnes public institute.  Mapping of infrastructure to establish market interest of operators and precisely define the areas where access to broadband electronic communication services is not provided by operators and also where no market interest in their provision in the next three years has been shown identification of white areas.  The market interest will be tested in areas whose population density is under 500 inhabitants/km2; areas that have already received structural funds will be excluded. The population density will serve as the basis for determining the geographic segment of high density with approximately 96 % of households and the geographic segment of low density with approximately 4 % of households. The target speed in the segment of high population density is 100 Mb/s, while the target speed in the segment of low population density is 30 Mb/s.  The number of white areas will be known after the testing of market interest and data analysis. In the event of a lack of market interest in the construction of broadband infrastructure and the resulting financial gap for the necessary co-financing from public funds, the state will attempt to provide the lacking public resources. If these resources cannot be provided, the plans shall be adapted by shifting the boundary between the geographic segments further to the urban areas with higher population density. This will broaden the geographical segment of low population density and narrow the segment of high population density. Testing of market interest for speeds of 30 Mb/s shall be repeated in the areas that were moved.  Co-financing public and private partnership for the construction of broadband infrastructure in areas where access to broadband electronic communications services is not provided by operators and where no market interest for their provision has been shown.  Realisation of the expressed market interest controlled by the Agency for Communication Networks and Services of the Republic of Slovenia (AKOS).  Promoting investments in broadband infrastructure in accordance with the provisions of the Electronic Communications Acts concerning the reduction of costs of broadband infrastructure construction.  Provision of additional segments in the radio spectrum for mobile communication networks to provide mobile access to the internet as a complementary communication service to fixed broadband infrastructure.  Promotion of the introduction of transmission of TV signals of higher definition (HDTV and UHD TV) in the terrestrial digital broadcasting network by introducing the DVB-T2 technology.  Preparations for compulsory integration of DAB receivers in radio receivers available on the market in 2018.  Promotion of development and introduction of advanced services by integrating the capacities of digital broadcasting, IP TV and the internet (Hbb TV, themed radio programmes, etc.).
