Iceland's national society, the IRA, reports on a case of a VDSL system allegedly failing in the presence of an amateur radio signal

The attention of the Board of Directors of the IRA has been drawn to the decision of the Post and Telecom Administration no. 17/2019 regarding radio interference caused by radio use, dated 16 July 2019, which has now been published on the Agency's website.

The presentation of the PTA Decision is as follows:

The Post and Telecom Administration received a complaint from the consumer for interruptions in telecommunications. The complaint stated that the neighbour's radio, which was a radio enthusiast, interfered with television reception and the quality of the complainant's internet connection. The complainant's demand was that an audit be conducted and a solution be found.

Following the PTA examination, it was clear from the Administration's opinion that radio broadcasts in certain frequency ranges from the neighbour's signal station caused telecommunications interference on the VDSL line of the complainant. The radio enthusiast did not consider that his equipment was malfunctioning and that his broadcasts were within the frequency range permitted to him under Art. license.

With this provisional decision, the PTA limits the radio amateur's authority to broadcast in certain frequency bands. The Agency refers to the principle that telecommunications plants have priority when it comes to its use and other devices or parts incompatible at the same place at the same time. In such circumstances, and in the event of malicious interference, appropriate measures should be taken with regard to the other item; the disruptive power, so that it is changed, removed or removed, cf. Article 64 Electronic Communications.

Radio amateurs were therefore made to limit the radiated power of their transmitters to specific frequency bands. In view of average proportionality, the Agency considered it appropriate to temporarily apply these instructions so that the transmitter and the radio enthusiast could be given room to take measures to resolve the interference problem.
