The Network Engineering Behind a Next-Generation 5G Infrastructure
Mobile connectivity in large sports venues has become an essential part of the digital experience. In a stadium such as the new Spotify Camp Nou, the network must be capable of supporting massive user concentrations, digital services, operational communications, and the connectivity needs of fans, employees, suppliers, and media representatives.
In this context, Orange announced in November 2024 the deployment of 5G Standalone (5G SA) infrastructure at the future Spotify Camp Nou, in collaboration with New Era Visionary Group (NEVG) as part of the Espai Barça transformation project. According to the official announcement, the goal is to provide high-capacity, low-latency connectivity while integrating the communications infrastructure with the venue’s systems.
As part of this project, 3dB Consult participated in activities related to the integration and transmission of new LTE and 5G NR nodes, contributing to the tasks required to extend connectivity from the access infrastructure to the transport network.
From the 5G Node to the Transport Network
When we think about 5G, we usually think of antennas, smartphones, or high connection speeds. However, a next-generation mobile network also requires a transport infrastructure capable of reliably connecting the various network elements and providing sufficient capacity.
In any new node integration project, connectivity does not end at the radio equipment.
Multiple infrastructure elements must be coordinated, including:
- New LTE and 5G NR nodes.
- IP addressing.
- Transmission service configuration.
- VLANs and associated connectivity.
- Transport routers.
- Connection and resource inventory management.
- Network databases.
- Connectivity testing.
- Integration validation.
- Incident resolution during deployment.
This transport layer is particularly critical in high-demand environments, where availability and the proper integration of all components are essential to delivering a consistent connectivity experience.
LTE and 5G NR Node Integration
As part of the work carried out by 3dB Consult, activities related to the integration of new LTE and NR-band nodes were performed.
The coexistence of different access technologies requires careful coordination of network configurations and transmission resources.
In this type of project, one of the main challenges is maintaining an end-to-end view of connectivity, from the radio node through the transport network and associated services.
The correct definition of IP parameters, VLANs, and connections ensures that all network components communicate according to the intended architecture.
IP Configuration and Transport Routers
A significant part of the work involved IP allocation and transmission configuration on NE8000 routers.
Transport resource configuration is a critical element of any mobile network deployment, especially when introducing new nodes and services.
This work includes activities such as:
- IP address allocation.
- Transmission service configuration.
- VLAN association.
- Review of physical and logical connections.
- Resource inventory management.
- Network database updates.
- Connectivity validation.
For services associated with 5G SA, proper inventory management of VLANs and IP resources helps maintain a structured view of the resources used throughout the infrastructure.
Technical Support During Field Integration
Network engineering does not end with logical configuration.
During integration windows, coordination between design, configuration, and field execution activities is essential.
3dB Consult provided support during integration activities, including:
- Cabling and connection verification.
- Connectivity testing.
- Validation of configured services.
- Incident identification and analysis.
- Technical coordination during integration windows.
- Validation of connectivity for newly integrated elements.
This approach helps bridge the gap between network planning and real-world deployment, reducing resolution times when issues arise during commissioning.
The Invisible Infrastructure Behind the 5G Experience
For end users, a 5G infrastructure translates into something seemingly simple: seamless connectivity, access to digital services, live streaming capabilities, and uninterrupted communications.
Behind that experience, however, lies a multilayered technical architecture.
In a deployment such as the new Spotify Camp Nou, connectivity depends on the successful integration of every component: radio systems, transport networks, IP addressing, VLANs, routers, databases, cabling, and validation procedures.
Orange’s project announcement specifically highlighted the need to provide low-latency, highly available connectivity for fans, employees, suppliers, and media through a state-of-the-art 5G SA infrastructure.
