Cosinor is the Elecnor Group company that specialises in Telecommunications Systems. It has grown out of the experience accumulated by the Elecnor Group in the control systems field since the creation in 1974 of the Industrial IT Division, going on to be the Group’s specialist subsidiary in this field.

Since January 2008, Cosinor has been responsible for all Elecnor’s telecommunications systems working teams, offering ready-to-operate services tailored to its customers’ requirements.
As the Elecnor Group has diversified and grown, Cosinor has developed systems projects in all the sectors in which the Group operates: Telecommunications Energy and the Environment, Construction and Real Estate, Security and, finally, Transport.

Cosinor maintains an autonomy that allows it to adapt both technologically and operationally to the development of a highly specific and extensive market across several sectors.
