The conditions for both running a company, living and working in a number of areas in Dalarna are adversely affected by the lack of access to broadband with high transmission speed (continually called “fiber” in this application). There is no market incentive for building fibre in the relevant areas. The reasons for this can vary from case to case. Central, however, is that the cost is too high in relation to the estimated revenue. A typical explanation is that the number of potential customers in the area is too small for a network owner to engage on purely market terms. If nothing is done, companies in these areas risk worse growth and, in the worst case, the conditions for remaining can become so bad that you are forced to move the business. Another circumstance that has affected many people in Dalarna is that telecom operators close down telecom stations. The result is that entrepreneurs and residents not only lack fiber but also lose their existing opportunities for broadband via xDSL. As the basic problem lies in the profitability calculations for these areas, one needs to look at the whole. In this context, companies form a subset of all potential customers. Although housing is not the primary target group of the project, it is also important for the project to be economically sustainable in the long term. The expansion of radio-based solutions and 5G is also dependent on nearby fibres to be able to deliver services in these areas of the same quality as in denser inhabited areas. As a result of this situation, we see that society needs to act to help ensure the opportunities to run companies, live and operate in these areas. The project “fiber expansion in Dalarna 2020-2023 (ERUF 5.5)” has been the eighth since 2015 (ERUF 1, 1.5, 2, 3, 4, 4.5 and 5). It is a direct continuation of the work to make Dalarna a modern and attractive environment to work in for, among other things, small- and medium-sized companies. In ERUF5.5, localised fibre networks are built to 17 areas where companies currently lack fibre. The project is well anchored in the county’s collaboration body Brodbandsforum Dalarna, where all municipalities participate.
