Founded in 1931, Azienda Trasporti Milanesi is a Public Limited Company owned by the Milan Municipality. It manages public transport in the Lombard capital and in 46 provincial towns, serving an area with a population of 2.51 million people.

Over the years, the services provided by the company have multiplied, both in the transport sector and in the commercial and leisure sectors. Today ATM is a company which designs and manages services and hi-tech systems for sustainable transport.

During Milan Expo 2015, Feedback Italia has been providing its secure videoconferencing solutions to connect the Main Operation Centre for control and security to various subsystems within the exhibition site, in common areas and in participating countries’ Pavilions.

Data from sensors located throughout the site have been collected towards the Control Room and correlated to provide a comprehensive overview of the situation, supporting the management of the large-scale event.

Integrating different networks, the solution provided by Feedback Italia allowed different communication terminals used by operators to "talk" to each other, even if they belonged to different networks, as well as being able to share evolved interconnection, localization and collaboration services.
