The school’s former computer science teacher contacted us following reading the article. He explains that he installed a “speaker” antenna in the teachers’ room, purchased in 2018, and intended to broadcast voice messages, as in department stores. But the “speaker” device never worked and the antenna simply served as a relay for broadcasting wifi in the school.
“I am very surprised to read all this following having devoted four years of my life to this school, when the organizing power has never taken the trouble to call me to ask me for an explanation. I would have gladly provided the documentation regarding this relay antennaconcludes the former computer science teacher at the school.
