What to do when the operation of equipment utilising radio frequecies is disrupted

In the case of interference with or errors in a signal, the operator of equipment using the radio frequencies or the provider of electronic communication services who provides them via equipment which utilises the radio frequencies, or the operator of radiocommunication services (hereinafter collectively referred to as the “operator”) must always first check its own radio equipment and make sure that it is in faultless condition. We recommend that such inspections are entrusted to a professional servicing company. It is neccesary to check:

  • the faultlessness and correct installation of the operated broadcasting and receiving equipment, including antennas and accessories
  • the quality of transmitted signal
  • the compliance with the minimum required level of the received signal
  • the appropriate sensitivity setting of the receivers (terminals)

Interference does not include the permitted sharing of frequencies of broadcasting radio equipment or the mutual interference of broadcasting radio equipment operating under a general authorisation. Such interference shall be dealt with by agreement between the operators of the equipment using the radio frequencies.

When ensuring the faultless functioning of operated radio equipment, the operator, in the case of interference or increased error rate in the signal, may ask CTU to identify the source of interference according to Section 100(6) of the Electronic Communications Act. In the case of doubt, CTU may require the confirmation of a professional company as to the faultless nature of the installed radio equipment.

If the interference is caused by non-compliance with the conditions laid down for the operation of the equipment, the costs of the protective measures shall be borne by the operator of equipment, otherwise the costs shall be borne by the operator of the equipment subsequently put into operation or modified. Where the interfered equipment does not comply with the requirements for electromagnetic compatibility, the costs of the protective measures shall be borne by the operator of that equipment. Otherwise, the operator of the equipment subsequently set up or modified shall bear the costs.

The locally-competent departments of CTU, whose addresses and contact details you will find in Directory, receive and handle reports of interference.
