Mobile phone communications have provided fertile territory for research into the spatial dimensions of communities. Studies of calling patterns have shed new light on the complex nature of networks. The analysis of billions of calls across a number of countries has led to a surprising conclusion: telephone exchanges are still largely dictated according to administrative boundaries laid down long before the arrival of the mobile handset.
Le téléphone portable est devenu un des principaux moyens de communication avec nos familles, amis et connaissances. L'étude des appels sur mobile peut donc nous aider à comprendre comment s'organisent spatialement les communautés. Or l'analyse de centaines de millions d'appels dans plusieurs pays aboutit à un résultat étonnant: les découpages administratifs continuent à structurer nos échanges.
