Abstract
On décrit un réseau de communications numériques dans lequel on utilise des techniques de communications numériques sonores et ultrasonores, c'est-à-dire des communications s'effectuant au moyen d'une énergie acoustique au lieu d'une énergie à fréquence radioélectrique. Le spectre acoustique, par opposition au spectre de fréquence radioélectrique, est dépourvu d'écho parasite et non régulé, permettant un développement commercial sans entrave de matériel destiné à des applications de système de transit intelligent (ITS), de même qu'une grande diversité d'autres applications, notamment des applications dans lesquelles on utilise des télécommunications à fréquence radioélectrique. A titre d'exemples d'applications, on peut citer le système de cabine téléphonique à paiement électronique, les système à entrée commandée, les systèmes de croisement de frontières, etc. On utilise des techniques de codage et de traitement qui permettent l'émission et la réception fiables de communications acoustiques, et notamment la communication de données numériques, même dans des environnement acoustiques bruyants.
