We are working on the intensive phase of the site preparation project for the sharing of facilities for the transmission plants of the two operators. This is a very delicate phase that requires a trade off between the needs and guidelines of operators and those of the tower owners of the structures. The complexity of this work has grown, but the challenge has not found us at all unprepared. We have been and are constantly able, starting from an in-depth study of the various technical/administrative aspects, to suggest the most appropriate solutions, even with the necessary structural reinforcements. We are successfully conducting complex electromagnetic impact analyses, providing customers with the database and scenarios in advance to reduce on-air time.
