O2 Telefónica and Samsung bring Open RAN and vRAN from the lab to the live network
O2 Telefónica and Samsung Electronics Co., Ltd. today announced that the companies have launched their first virtualized RAN (vRAN) and Open RAN commercial site in Germany. It is the first time that Samsung’s 5G vRAN solution is being used in a commercial network in Germany. The site is now operating in Landsberg am Lech, Bavaria, providing high-performance and reliable 4G and 5G services to customers. In the coming months, the companies will expand the vRAN and Open RAN network to seven additional sites in the region, aiming to further extend the Open RAN footprint. This milestone builds on the companies’ joint initiative, announced in October 2023, where they agreed to develop a roadmap for several tests of vRAN and Open RAN technologies. Following the extensive trials, O2 Telefónica and Samsung are now progressing from lab to field with the launch of this first commercial site.

Open RAN and vRAN - Bringing Greater Flexibility and Automation

The first Open RAN site with Samsung technology
O2 Telefónica is building an even more efficient and future-proof network leveraging modern and advanced RAN technologies, open interfaces, and automation capabilities. Open RAN enables greater flexibility in the mobile network. Based on open interfaces, operators can combine network components from different providers and integrate them into their network. Software-centric vRAN helps the adoption of cloud-native architecture, allowing network operators to better automate functions, introduce new technologies and services to their networks quickly and efficiently. This is important for accelerating network buildouts and adopting new 5G applications, including use cases that require low response speeds, such as virtual and augmented reality (VR/AR) or latency-critical applications for enterprises.

Samsung’s Advanced and Proven Network Solutions

The companies have successfully switched on this first commercial site just three months after the initial shipment of 4G and 5G solutions, leveraging Samsung’s expertise and pre-validated ecosystem proven from large-scale commercial vRAN and Open RAN deployments across the globe. For the initial deployments, Samsung’s offering includes its market-leading 4G and 5G vRAN 3.0 solution and O-RAN compliant radios supporting low- and mid-bands (700MHz, 800MHz, 1.8GHz 2.1GHz, 2.6GHz, and 3.6GHz), including 64T64R Massive MIMO radios. Samsung’s advanced vRAN 3.0 features enhanced capabilities for improved energy efficiency, optimized performance and intelligent automation. As the next step, the companies will introduce Samsung’s intelligent network automation solutions to control life cycle management—from deployment and operation to maintenance. This O-RAN compliant automation solution offers the ability to accelerate innovative software-based network rollouts by enabling automated deployment of thousands of network sites simultaneously.
