1&1 has become Germany’s fourth mobile network operator following the launch of its first smartphone tariffs last week. 1&1’s fully virtualised mobile network is based entirely on Open RAN technology. Initially, where there is no dedicated coverage during the rollout phase of the new 1&1 mobile network, customers automatically have access to Telefonica Deutschland’s 2G/4G/5G network as part of national roaming now expanded to include 5G. From 1 July 2024 1&1 will use national roaming from Vodafone as planned and reduce, step by step, upfront services from Telefonica.
Unlike traditional networks, which are based on proprietary technology from specialised network suppliers, the 1&1 O-RAN has a large number of standardised interfaces, allowing software and hardware components from different suppliers to be flexibly combined and eliminating 1&1’s dependence on individual suppliers.
