1&1 (DE0005545503) is pushing ahead with its positioning as a German converged telecom provider. The TecDAX-listed company is rolling out its own 5G network while deepening wholesale fibre partnerships in key regions, according to recent corporate disclosures and partner statements.
5G rollout with network partners
The company is building a fourth mobile network in Germany based on 5G and Open RAN technology, using a host network from Telefónica Deutschland in the transition phase and partnering with Vantage Towers for radio sites as outlined in prior agreements. A Vantage Towers partnership announcement describes a long-term deal for thousands of antenna sites.
The 5G network is designed to handle rapidly growing mobile data volumes from 1&1 customers, with Open RAN expected to provide more flexible deployment and vendor mix compared to traditional architectures. The company aims to gradually migrate traffic from the national roaming arrangement to its own 5G infrastructure as coverage improves in coming years.
Fibre and fixed-line cooperation in the north-west
On the fixed-line side, 1&1 is sharpening its regional reach through wholesale agreements with local fibre operators such as EWE TEL in north-west Germany. EWE TEL, a regional carrier, reports that it makes its fibre-to-the-home network available on a wholesale basis to partners like 1&1 and Deutsche Telekom to improve utilisation of its infrastructure. An EWE TEL cooperation overview highlights the wholesale model and partner access to high-speed lines.
These wholesale-based partnerships allow 1&1 to offer customers fibre connections with gigabit speeds in selected regions without building every metre of network itself. The strategy complements its own DSL and VDSL offerings, which are largely based on long-standing wholesale access to incumbent networks in Germany.
