Collecting data on NGA
CTU performs by its Electronic data collection (ESD) system a regular annual data collection on the existing electronic communication networks with focus on the identification of NGA connections allowing the provision of internet access service with the speed of 30 Mbit/s and higher. The data is sorted geographically according to address points as defined in the Register of territorial identification, addresses and immovable property (RÚIAN). CTU collects data disposable to 31 December of the year.
The data is primarily processed in compliance with the guidelines of Ministry of Industry and Trade (hereinafter "MPO") and further used for the implementation of National plan for the development of new generation networks and preparation of its updated versions for programming period 2021 - 2027; for the preparation of documentation and activities connected with the subsidy program for the support of high-speed networks deployment (OP PIK, specific goal SC 4.1); and also for the preparation and execution of measures for the support of high-speed networks deployment on the demand side. CTU also uses the collected data for secondary proposes (e.g. market monitoring, market analyses, inspection etc.).
Operators submit the numbers of disposable connections for each of the relevant technologies (FTTH, FTTB, FTTC, xDSL (FTTC and xDSL technologies fall into one category as of 2016), CATV, wireless technologies in licenced bands and wireless technologies in licence-exempt bands. Such connections are existing or easily deployable (i.e. without major costs and in short time), sorted according to the effective speed of the internet access service up to 30 Mbit/s, between 30 and 100 Mbit/s, and over 100 Mbit/s (since 2019 devided into speed categories between 100 Mbit/s and 1 Gbit/s and over 1 Gbit/s).
For identification of locations potentially qualified for subsidies CTU aggregates the gained data to higher regional units, so called basic residential units (ZSJ). For all ZSJ the calculation gives a “colour marking” which indicates the level of coverage of the residential unit by the infrastructure. When calculating "colour marking" the ratio of number of address points with at least one disposable NGA connections to the number of all address points in the ZSJ is calculated. CTU performs the assignment of “colour marking” according to the criteria agreed in a working group established for the infrastructure surveys. This working group was led by CTU and attended also by members from the industry and MPO. The methodology is the following: If the ratio is lower than 50% the ZSJ is marked as “white”. If the ratio is higher, CTU investigates the number of undertaking which indicated any number (above zero) of disposable connections in the unit. If the number of such undertakings equals to 1 the unit is marked as “grey”. In all other cases the unit is marked as “black”.
The collected data and the results of above mentioned data processing are submitted by CTU to MPO. Further use of the results to identify specific intervention areas is already within the competence of the MPO, which applies its own methodologies to define "colour marking" of ZSJ.
