On the issue of securing 5G networks, the GSMA is calling on European policymakers not to lose focus on the big policy objectives – security, competition, innovation and consumer impact.

The recommendation is for European policy makers to adopt a fact-based and risk-based approach, recognizing the mobile operators already have considerable experience in securing their networks; that government agencies and mobile operators already cooperate in safeguarding the integrity of telecommunications infrastructure; and that further testing by mobile operators and third-party laboratories could help assure confidence in the network.
