The collaboration aims to drive digitalisation and industry cooperation through advanced network infrastructure.

Boldyn Networks (Boldyn) announced a significant agreement with the Centre Tecnològic de Telecomunicacions de Catalunya (CTTC) to deploy a highly advanced private 5G network across its research facilities in Barcelona for fast, reliable, and high-capacity wireless connectivity. This initiative marks a major step forward in accelerating digitalisation and fostering industry-wide collaboration. 

The network leverages the full spectrum of self-providing frequencies available in Spain for industrial use -including mid and high frequency bands as well as millimetre waves -and ensures both indoor and outdoor coverage throughout the CTTC campus. This is one of the first commercial deployments to utilise all these bands simultaneously. 

The deployed network consists of two cutting-edge standalone 5G cores featuring Network Exposure Function (NEF) and roaming capabilities. These provide programmability and flexibility, giving the ability for devices to seamlessly connect to different 5G networks as they move between coverage areas. This is crucial for CTTC as it allows for continuous connectivity and testing of various use cases. 

CTTC is especially interested in testing use cases like critical communications, autonomous driving, and immersive technology experiences (VR/AR/XR). The infrastructure also lays the groundwork for future 6G technology-based use cases through the efficient integration and interoperability of different end devices, from smart glasses and sensors to cameras and VR/AR headsets. 

The project is funded by Spain’s "Ministerio de Asuntos Económicos y Transformación Digital" and the European Union-NextGenerationEU in the frameworks of the European Union’s Recovery, Transformation, and Resilience Plan through the UNICO Plaza6G project. The primary goal is to advance telecommunications research and offer an advanced programmable 5G network infrastructure so that companies can validate industry standards, test their use cases, and generate valuable knowledge. 

Mikko Uusitalo, CEO, Europe at Boldyn Networks, said: "We are excited to partner with CTTC on this groundbreaking project. This collaboration not only underscores our dedication to advancing private 5G technology but also aims to highlight the transformative potential of private 5G networks across various industries. By leveraging the available spectrum in Spain, we aim to empower industrial companies and enterprises to maximise the use of industrial spectrum through self-provisioning. CTTC will offer this new infrastructure to companies to drive digitalisation across the industry. This initiative will pave the way for innovative applications and drive significant advancements in digitalisation." 

Josep Mangues, Research Director and Head of the Services as networkS (SaS) Research Unit at CTTC said: "Deploying an advanced private network is a significant step forward for our research and development efforts. The programmable private 5G network will become part of our experimental facilities and enable our researchers and industry partners to explore new use cases and push the boundaries of telecommunications technology. We are excited about the opportunities this collaboration brings and look forward to driving digitalisation across various sectors."
