Blick auf Perspektiven mittels einer möglichen weiterführenden Koop mit Rakuten und auf geschätzte Aufbaukosten:

"According to Rabih Dabboussi, Rakuten Symphony's chief business officer, this could support a major rearchitecting in the future. RAN software is normally hosted at the base of a site in a traditional network, but 1&1 could theoretically pool the central units (CUs) hosting much of this software in its "edge" facilities, leaving only distributed units (DUs) responsible for baseband functions at the sites, he explained to analysts and reporters during a briefing at the UK office.
"That gives us the flexibility to move the user plane function all the way to the edge and when we did that the latency on Minecraft became three milliseconds, which is unheard of in any legacy architecture," he said. "Gaming is becoming one of the biggest 5G needs when it comes to latency and bandwidth."
If such features help it to lure mobile customers from the networks of Deutsche Telekom, Telefónica and Vodafone, the upfront costs will be easier to justify. As a mobile virtual network operator piggybacking on its rivals' infrastructure, 1&1 was able to boast nearly 11.7 million customers at the end of last year. Still, its costs today include payments to competitors for the use of their networks. These should at least disappear when it has built its own.
Reselling Rakuten's rich portfolio of e-commerce and entertainment services to German consumers could be another potential upside for 1&1. While no arrangements have been thrashed out, there is a possibility of 1&1 playing this sort of role in future, Karaiskos told Light Reading. Bundling its own connectivity services with Rakuten's TV, banking and other products would give 1&1 something its rivals lack.
Right now, that seems a long way off. Dabboussi reckons a traditional mobile network costs between €200,000 ($217,540) and €250,000 ($271,925) per site in capex alone, plus another €15,000 ($16,316) to €20,000 ($21,754) for annual maintenance. Rakuten believes its platforms and technologies can save customers 40% on capex and 30% on opex, but this would still leave 1&1 facing an upfront bill of around €3.2 billion ($3.5 billion) to build a nationwide network of 26,000 sites, as Vodafone has done."
