Telefónica modernizes home network management for millions of Spanish households
Telefónica, a leading telecom provider in Spain, implemented an advanced IoT platform (HAC) using Microsoft Azure IoT Hub and Azure Event Hubs. The platform centralizes and automates the management of home internet connectivity for over 4.5 million households, with plans to scale to 20 million. By leveraging Azure's device provisioning and event ingestion capabilities, Telefónica improved operational efficiency, predictive maintenance, and customer service. The architecture integrates device telemetry for anomaly detection, enables in-depth diagnostics (including customer self-service), and supports rapid integration of new features. The project included close collaboration with Microsoft experts, ensuring strong data privacy, cybersecurity, and virtually unlimited scalability. As a result, Telefónica drastically cut development times, reduced manual processes, and delivered consistently better connectivity experiences to customers.
