TLC infrastructure and services

This has always been a strategic area of business for the Group, which pays constant attention to its every aspect, such as construction site organisation and the creation of infrastructure using the most advanced technologies (passive solutions and active apparatus).
Valtellina has become an increasingly visible point of reference in the development of both fixed networks (ultra-broadband services, also in FTTH mode) and mobile networks.

The company is a renowned specialist in both the laying of fibre optic cabling at industrial and advanced service sector sites and the revamping of telephone exchanges and data transmission centres with complete Wi-Fi coverage and VoIP-Data Cloud services.

Network infrastructure and the necessary equipment are made to measure for each project, choosing the most appropriate technique case by case. We install the most advanced systems available for both urban road systems and building interiors.
