Mexico’s Federal Telecomunications Institute (Instituto Federal de Telecomunicaciones, IFT) has fined America Movil (AM) subsidiary Telefonos del Noreste (Telnor) a total of MXN1.3 billion (USD69.7 million) for failing to disclose full details regarding the availability and technical characteristics of its networks. Telnor, which operates in north-western Mexico (including Baja California and Sonora), is – like its better-known sister company, Telmex – classified as a Preponderant Economic Agent (Agente Economico Preponderante, AEP). As such, Telnor is obliged to inform the regulator – and in turn the other concessionaires – of its network availability, so other operators can utilise excess network capacity.
