The fast-growing services being offered by Over-The-Top (OTT) players is starting to impact the ability of mobile operators to meet future investment requirements, warned Franco Bernabè, Chairman, GSMA, and Chairman and CEO, Telecom Italia, during his keynote presentation at this year’s GSMA Mobile World Congress. “These new OTT players have based their innovation in the mobile domain, without a deep understanding of the complex technical environment of our industry. This is increasingly creating significant problems to the overall service offered to the end user and driving additional investments for mobile operators,” said Bernabè.
