Experimental and Trial operation

EETT grants temporary radio spectrum rights of use exclusively for experimental, research, pilot, trial, demonstration or similar purposes.

Licensing conditions

Radio spectrum rights of use for the purposes above are granted on a non-interference and non-protection basis to existing systems/radio spectrum uses, if any. Holders are solely responsible for complying with the conditions of the granted rights. The rights are granted provided that there is availability of spectrum and that any technical and other conditions, provided for by relevant legislation (available in greek), are fulfilled.

The use of these rights for the provision of electronic communications services to the public or for private needs is prohibited.

In order EETT to verify that an application falls under the above purposes, it may request relevant certificates and other statements as well as anything else it deems necessary to document the feasibility and the duration of the application.

It is pointed out that this responsibility of EETT does not involve networks of public education institutions and other state networks.

Radio equipment

For the radio equipment to be used, all conformity assessment procedures provided for by the Presidential Decree No. 98/2017 must have been fully followed. Especially for the spectrum rights of use for experimental and research purposes, the emissions may be allowed also with the minimum condition that appropriate measures have been taken under the responsibility of the owner of the temporary radio spectrum rights of use based on the existing legislation to avoid harmful interference, electromagnetic disturbances and risks to the health or safety of persons or pets as well as the protection of property.
