Telecommunication Networks
Dominion Global

The telecommunications sector is an extremely competitive industry that has seen a continued decrease of operating margins over the past few years. We have been working in the sector for over 20 years, remaining competitive by continually improving our operations by incorporating digital tools.

The expertise we have amassed over the years has converted us into a benchmark partner for our clients in terms of the integral management of their telecommunications networks at an international level. 



Since the beginning we have always focused a significant portion of our activity on the telecommunications sector. Once we had established ourselves in Spain, we started expanding onto the international market, especially into Latin America, and we have since become a supplier with the capacity to operation on an international scale.

Some of our clients are the world's leading operators: Telefónica, Vivo, Orange, Vodafone, Entel, Claro TIM, GVT and many more.
Our services cover the entire life cycle of telecommunications networks, from the design and laying to subsequent maintenance:
