About Bouygues Telecom

 

Bouygues Telecom is a global communications operator who brings the best of technology to its 20 million customers every day. The excellence of its 4G network, its fixed-line and cloud services enable people to enjoy their digital life simply, fully and wherever they are. Bouygues Telecom is proud of the innovations brought to the French over the past 20 years. Their strategy will always remain the same: to democratize new technologies.

 

CONTEXT

 

Launched in February 2013, the “France Très Haut Débit” plan aims to cover the entire country in very high speed by 2022, i.e. to offer high-performance Internet access to all housing, businesses and administrations. In urban areas (large conurbations and departmental capitals), private operators have invested several billion euros in the deployment of their fiber optic networks to the subscriber. Faced with this colossal task, telecom operators call on large service companies to take charge of fiber deployment and connection to customers.

 

CHALLENGE

 

At the end of December 2018, Bouygues Telecom marketed 7.2 million Fiber to the Home (commonly known as FttH) outlets; and the number keeps growing. In order to connect all its customers, the company must perform several thousand operations per day and uses several subcontracting companies for this purpose. Due to the explosion in fibre connection volumes, the quality of interventions is not always consistent and it is sometimes necessary to intervene several times to connect a customer. It is impossible to control all interventions and only 5% to 10% of the installations are controlled. 

On the other hand, the explosion in the demand for interventions puts pressure on technicians who, due to lack of time to manage the most difficult situations, may fail to follow certain procedures. As a result, the network is gradually deteriorating due to non-compliant installations.

Faced with fierce competition, Bouygues Telecom wants to differentiate itself by offering a quality of service that is superior to that of its competitors. This quest for quality is at the heart of the company’s transformation process.

Our priority is the quality of the customer experience, but this is difficult to guarantee when you perform thousands of interventions every day. With Artificial Intelligence and Deepomatic’s solution, we can achieve this goal. In addition to carrying out large-scale controls, this tool allows our operational staff to focus on tasks with higher added value.”

SOLUTION : From post-control to real-time analysis

 

Deepomatic has developed a quality control solution for Bouygues Telecom to detect the presence of anomalies in technical intervention photos. 

Equipped with a smartphone, the technician mandated to connect a customer to the fiber, takes a picture of the location where the connection between the optical fibers of subscribers and commercial operators is made. 

The photos are analyzed in real time in the cloud by Deepomatic-driven image recognition neural networks and report anomalies such as unconnected fiber, bad colors or passage defects in the cable paths. Real-time analysis allows defects to be corrected immediately instead of having to plan a rework later. In case of doubt, the algorithm raises an alert and a technician makes the final decision, thus making it possible to solicit their expertise on complex cases only.

RESULTS

 

The neural networks trained by Deepomatic successfully recognize more than 75% of defects, a figure that is constantly increasing. Thanks to the Deepomatic platform, production performance improves and algorithms adapt to the appearance of new defects. The project initiated at the level of interventions on the points of mutualization (PM), but the application could cover all the different areas of intervention of the technicians. 

  • Comprehensive monitoring of FttH fiber optic installations
  • Concentration of operational activities on high value-added tasks
  • Evolution of control algorithms according to quality requirements

 

“We have already identified a number of vulnerabilities in the connections. But nothing says that others will not appear. Deepomatic’s software can adapt and take into account new defects.
