C'est pas sorcier - Season 1 Episode 202 Le téléphone portable
Fred et Jamy nous expliquent tout sur les téléphones portables : leur fonctionnement, leurs avantages et leurs dangers… Nous découvrons avec eux quels risques ils comportent pour la santé, de quelle manière ils peuvent constituer une réelle entrave à nos libertés et quelles innovations techniques les fabricants nous concoctent actuellement. Comment un téléphone cellulaire fonctionne-t-il ? Comment la voix est-elle reçue puis reproduite par le téléphone ? Pourquoi les systèmes numériques sont-ils plus performants que les systèmes analogiques ? Comment les ondes émises par le téléphone sont elles transportées puis reçues ? Pourquoi y a-t-il régulièrement des problèmes de saturation sur les lignes ? Comment les interconnexions permettent-elles de ne pas interrompre la communication quand on se déplace ? Pourquoi peut-on être localisé à tout moment quand on possède un portable ?
