The project aims at facilitating cooperation among national telecom regulators across Europe by creating, publishing and reusing open data related to broadband Internet on a newly created platform.

The project will establish a cross-border platform for crowdsourcing data related to the quality of service of high-speed Internet. Part of the platform will be enlarging and improving the application for collecting data on both mobile broadband and fixed-lines. 

These applications will be operated directly by national telecom regulators from the Czech Republic, Slovakia and Slovenia, who will guarantee the accuracy of the data and at the same time use them for comparison with data provided by operators and ISPs, as well as for other analyses e.g. indicating meeting (or not meeting) the broadband coverage in rural areas. In total, at least 300.000 tests in in the four participating countries will be performed during the project.

The platform will also contain visualization of aggregated data allowing end users an easy check of the quality of coverage at a given place and will enable the data to be published on national and European open data portals.

An integral part of the project will involve proposing a data standard based especially on the BEREC recommendation and related EU requirements.

About Open Nettest

Open Nettest is an open-source platform, which measures the Internet connection with a strong focus on quality and reliability. Besides usual indicators like upload and download speed, Nettest performs over 70 unique tests aimed to assess the quality of connection and net neutrality. With more than 80 parameters measured, Nettest is probably the most holistic measurement tool available in the market. Nettest is currently being used by several European regulators. It is vendor-independent, based on crowd-sourcing, open sourced and able to output anonymised open data.

Nettest is a proven solution which has been tested and fine-tuned in several implementations, thus reaching status of maturity comparable to or even outreaching proprietary commercial systems. The system can be deployed within a few weeks enabling us to prototype the platform very early and add features iteratively according to the actual priorities. The discussion about priorities and deployed features happens regularly among the product owner and the stakeholders as the project progresses.

Nettest is in full compliance with BEREC reports from 2014 and 2016 that recommends parameters of IAS quality monitoring system. Open Nettest is a complex tool offering reliable and credible testing of internet connection. It offers complex information regarding connection quality of all users. It is possible to compare results between end users of all operators. It offers the possibility to determine the level of user satisfaction with their internet connection, as well as with their internet provider. It allows for detailed comparison of real results with outputs of testing applications of mobile operators. The platform is based on the principles of crowd sourcing – very effective data collection method using smartphones and other devices with web browsers. It provides well-organised, detailed graphical and statistical depiction of results, as well as mapping of testing processes for all users.

It enables rapid implementation due to its open source and fast deployment nature. It uses open-source and open data principles to maximize benefits for both regulators and end users.

The platform reduces regulator’s operation costs. It enables easy measurements of the internet connection quality. It provides reliable documentation in case of a litigation.

It promotes the end user enablement through the availability of real internet quality data, the data for efficient complaints resolution. It also enables the user to make informed purchasing decision when selecting ISP and thus increases market competition, leading to an increased level of user satisfaction.

The main benefits for European regulators

Other EU regulators can participate in the project activities free of charge. In particular, they can use the measurement platform and obtain the corresponding apps for use on their local market.

The main benefits include:

  • Measurement tool for web, iOS and Android provided free of charge,
  • Regulator get access to measurements from his country as raw data / open data,
  • There is no setup cost and no operational cost.

Optionally, regulator may choose to host their own measurement server in their country, most likely in a national peering center. The project team will provide complimentary support with the Linux-based server software. The cost of hosting, operation and connectivity is the respective regulator’s responsibility.

Regulatory Compliance

The European Commission is forcing national regulatory authorities to monitor net neutrality, though not describing how it could be measured. For that reason, BEREC published recommendations on internet coverage and quality tests in the context of net neutrality. Open Nettest is fully compliant with the BEREC recommendations as indicated in table 1.

Principle stated in BEREC report

Nettest compliance

Minimal IP layer measurements

Nettest measures following IP layer parameters: upload and download speed, delay, jitter, and packet loss ratio.

Include all types of IAS

Nettest measures both fixed and wireless/mobile Internet access services.

Monitoring degradation of service

Measurements are conducted over time to allow trend analysis, reflecting potential degradation of IAS as a whole.


Averaging, based on data gathered from all participating users, is based on crowd-sourcing.

Software-based agent

A software-based measurement agent is available for download to end user equipment.


Measurement results are obtained from a clearly defined population and their statistical treatment is well documented, so that results can be interpreted without bias.


Nettest allows “plain” comparability of individual sample measurements, but also comparability at higher levels, such as comparability between IASes, so that degradation can be identified with a sufficient level of confidence.


Nettest components are robust and protected against security attacks, and availability, integrity and confidentiality of the measurement data is secured during storage and transmission.


Nettest users are informed which data are collected, for what purpose and what information is included, how data will be used, and specifically that some information may be made available to the public.

Legal value

The system governance is designed in a way which mitigates conflicts of interest and ensures credible results. Measurements undertaken with Nettest can be used in legal litigations.

End user enablement

Nettest is objective and provider-independent, thus enabling users to undertake measurements, on which they can rely on and make further use of.


The system design ensures flexibility, extensibility, scalability and adaptability.

Open source code

Details about the measurement methodology are available. Open source code is used and publicly known, making the measurement methodology transparent.

Open data principle

Collected data are known and publicly available (with due respect for the limitations of national legislation).


Nettest is a cost-effective solution, regarding all phases of the measurement system lifecycle, including development, deployment and operation.

Open Source

Open source means that the source code of Open Nettest software is publicly accessible and that Specure has put the components it has developed under an open source licence. This is for transparency and reliability reasons to make it possible to understand the test methodology by viewing the actual source-code, and to ensure that measurements are correct and reliable.

Open Data

Open Nettest comes with a JSON interface to publish all measurement details. Any interested party is allowed to use these data for any reason. This guarantees independency and reliability of the measurements details. Of course, all data is anonymized before putting it publicly to open-data.

Easy to Use

Open Nettest allows users to obtain information on the current service quality of their Internet connection in the context of net neutrality and provides them with comprehensive information, including statistical data. Open Nettest provides:

  • a speed test for download speed, upload speed and round trip time (ping);
  • several quality of service tests, which determines net neutrality. This includes testing of TCP-/UDP-ports, a VOIP/jitter test, proxy tests, DNS tests, etc.;
  • a map view of all test results with filter options for test parameters, statistics, operator, device and time of day;
  • several in-depth statistics;
  • a red/yellow/green evaluation of the test result (“traffic-light”-system);
  • the option to synchronise results of various devices and display them in the browser;
  • the user’s own test history,
  • representative, comparable test results, statistical analysis and visual illustration via heat map.

Privacy and security

All public available test results are exclusively providing anonymously data.

By anonymization personal data will not be available online. In particular, the following parameters will not be published: Measure ID of the client, sync code and sync group of the clients, the complete IP address, Wi-Fi network name (SSID) and Wi-Fi numeric identifier (BSSID).

The end user confirms the privacy policy prior to measurements. This also contains the information in detail, which data is collected 

and stored. The data protection regulations will be drawn up by a lawyer who is specialized in privacy.

All personal data, even those that are not publicly displayed will be anonymized after a certain period of time. E.g. after 6 months. This anonymization also has to be performed in backups.

The transmission of the data provided by the test client is only possible through HTTPS respectively TLS secured connections.

On all platforms the user receives upon location tracking an announcement which he has to approve or reject.

If an open data interface is desired, the client can accurately determinate the date to be accessible by the public.
