4.1.1 Map of coverage in 2016 With effect from 1 January 2016 the system of annual electronic data collection performed by the CTO will also include forms for collecting geographic data about selected parts of network infrastructure, in particular data (starting with data for 2015) mapping the existence of network infrastructure enabling the provision of services determined through the parameters in accordance with the objectives of the strategic document Digital Czech Republic 2.0, meaning electronic communications connections on which it is possible to provide an Internet access service with speeds in categories up to 30 Mbit/s, from 30 to 100 Mbit/s, and over 100 Mbit/s. Using the geographic breakdown, data are also collected about the actually provided Internet access service in the location in question using this infrastructure, except address points. In this connection it is important to add that the qualitative parameters of the provided service need not always correspond to the potential of the infrastructure through which the service is provided. The data about network infrastructure are collected broken down into separate technical solutions. What is decisive is the actual ability of the electronic communications networks to achieve the relevant speed in the direction towards the user on the number of electronic communications connections presented by an enterprise. This collection also considers the so-called available electronic communications connections, generally defined not only as the existing state of the electronic communications networks, but also with regard to the potential for its easy completion or upgrading in accordance with the requirements for the qualitative parameters of the provided services. It is a general guideline, and the assessment of such potential is fully the responsibility of the enterprise completing the form. Only the enterprise is able to consider - when completing the form - how many additional electronic communications connections with the required parameters it is capable and willing to construct over the next three years. When providing the number of available electronic communications connections, it is not possible to assess only the actual capability of the access part of the network to provide a service with the given parameters – it is also important to assess the relevant connectivity in that part of the backbone connection to ensure that the end users are genuinely able to consume services of the given quality. The enterprise is responsible for the correctness of the data provided. In the event of doubt, the CTO (and also the OP EIC Managing Authority) may check the correctness of the data, including through an on-site inspection if required. The OP EIC Managing Authority may also apply tools, including those indicated in point 65 of the EU Guidelines. To increase the efficiency of the process of mapping the coverage of the Czech Republic with high-speed Internet access networks, a two-stage model was selected based on data from previous network mapping performed by the CTO in 2013 and after expert consultation to localise areas where it is possible to provide support for the construction of NGAs and also effectively ensure protection for existing private investments into the construction of highspeed networks. The first step involves the mapping of existing networks down to the level of individual address points in each basic settlement unit. If, in such BSU, there is the possibility of highspeed Internet access for less than 50% of the address points, that BSU will be labelled a “white BSU”. The value of 50% was discussed at national level by the working group for mapping. The professional public and the MIT participated in this working group, headed by the CTO. The Ministry of Industry and Trade applied the level of parameter as per the EU Guidelines. 18
