ANFR will release one of its investigations from time to time. This week, a jammer blocked the operator’s 3G service in Guyney (Sena Saint Denis). This interference interferes with public health facilities that specialize in mental health. The National Frequency Agency (ANFR) has released a survey it conducted. After the box malfunctioned, the jammer encountered a 3G cellular antenna.
On March 30, the operator reported one of the relay antennas to ANFR. In this 3G antenna area, operators cover Evrard’s public health facilities that specialize in mental health. The next day, two ANFR agents were sent to the site: they found that they used a cell phone portable jammer that they prohibited. The source comes from a building with 4 apartments and 1 business room.
With the consent of the manager, the investigators entered the premises and found no jammers. Then they turned to individuals. However, since investigators were unable to benefit from the privilege of analyzing private spaces, they decided to challenge residents by removing the artificial ban law (a fine of 450 euros). A few minutes after the intercom, the fault disappeared.
