Use of analytical services

We use a seperate instance of the web analysis programme Matomo (formerly ‘Piwik’) on our website. This programme allows us to track the use of our website and to optimise it if necessary. For this purpose, ‘Pikwik’ uses so-called cookies. These are small pieces of data stored on your computer. The resulting usage information and your IP address are forwarded to our server and stored in order to analyse your usage behaviour. During this process, your IP address is made anonymous immediately so that no links can be made to you as a user. The information obtained in this way will not be passed on to third parties. You can change the settings of your browser software to prevent cookies from being stored. In doing so, however, you may not be able to use all functions of our website to their full extent.

You may turn off the storage and usage of this data at any time during your visit to our website. All you have to do is tick the box below so that the tick is no longer shown in the box (opt-out procedure). In this case, a so-called opt-out cookie is stored in your browser, which prevents Matomo from collecting session data. Please note that deleting your cookies means that the opt-out cookie is also deleted and may need to be reactivated the next time you visit our website.

Creation of this declaration on accessibility

Declaration on accessibility

The project managers endeavor to make their website accessible in accordance with the national legal provisions for the implementation of Directive (EU) 2016/2102 of the European Parliament and of the Council.

Creation of this declaration on accessibility

This declaration was created on December 2nd, 2020. The last review of the website of the N5GEH project and this declaration was carried out on December 2nd, 2020.

The basis for the creation of this declaration on accessibility is a BITV self-test carried out by the TU Dresden, see Article 3 paragraph 1 of the Commission’s Implementing Decision (EU) 2018/1523).


Status of compatibility with the requirements of the BITV

This website is not compatible with the requirements of the BfWebG in connection with the BITV 2.0. The incompatibilities and / or exceptions are listed below.


Non-accessible content

  • Alternative texts are not fully available or are not always fully meaningful
  • The headings are only partly correctly set.
  • The contrast values are partly too low, this mainly affects the spot color turquoise.
  • The “Wiki” is not accessible via keyboard.
  • The interactive graphic under “Discover” is not accessible via the keyboard, but the “Site Overview” can be used here to access the content.


We have a very extensive and diverse website with a large number of documents. This was published before September 23, 2018 and therefore does not reflect the current status of accessibility. We are trying to break down the barriers, but due to the resource situation in the project operation, we are currently unable to provide a fully accessible website. Contact us by phone or email if (parts of our) content is not accessible to you. We will then try to provide the information you require.


If you notice any deficiencies with regard to the barrier-free design, please contact
