The jamming occurred exclusively at night, never before midnight. The investigator, equipped with a spectrum analyzer and a direction finder, therefore launched his investigations in the middle of the night, from the antenna of the mobile operator. His devices identify the culprit: a wave jammer, a material prohibited for use and sale in France.
No internet at night
The technician approaches the source of the jamming, which he detects without any doubt possible in a house in a neighboring town. He obviously won’t knock on the door of the sleeping household. He therefore returns the next day with a judicial police officer.
The occupant of the premises will recognize having purchased on the Internet a multi-band jammer, capable of acting on radio frequencies as well as on Wifi. For this father, it was the only solution to ensure that his teenagers were going to bed and not spend part of the night on social networks and other applications.
A solution that the ANFR describes as “radical but above all illegal and disproportionate”. Because the jammer started by the father did not only deprive his children of the Internet but disrupted the mobile reception and Internet of his neighbors, in two municipalities. The father of the family is now liable to criminal prosecution.
