The development of of wireless technology applications means there are increasing numbers of users of the frequency spectrum and therefore more risks of interference which can hinder or even prevent all uses of a frequency band within a given area. Through its interregional services and branches in the French overseas territories, ANFR agents conduct true investigative work to find the sources of interference and put an end to disruptions.
The publication of investigations, which describe the actions taken by ANFR staff to resolve interference cases, illustrates the risks involved in misusing radio frequencies. The purpose of these investigations is to raise public awareness of the proper use of frequencies, radio equipement ans also electric and electronic equipement, so as not to be a cause of interference, and of the importance of knowing how to react effectively when one is victim of an interference, in particular by alerting ANFR
To mark its 25th anniversary, ANFR has compiled 25 of its most eye catching investigations in a book. In cities, in the mountains, in the countryside and even on the high seas, discover the adventures of the guardians of the spectrum.
