The Mobile World Congress (MWC) 2025 in Barcelona has underscored a plethora of groundbreaking trends and innovations, effectively setting the stage for the next wave of developments in the telecom industry. This year’s event has brought critical themes to the forefront, including the integration of artificial intelligence into Radio Access Networks (AI-RAN), notable advances in Open Radio Access Networks (Open RAN), and significant progress in Non-Terrestrial Networks (NTN). Each of these themes marks a pivotal advancement within the telecom sector, promising to revolutionize network functionalities, enhance connectivity, and support the burgeoning demand for faster and more efficient communication.

AI-RAN

The introduction of artificial intelligence into Radio Access Networks (AI-RAN) quickly emerged as one of the major highlights of MWC 2025. Celebrating its first anniversary, the AI-RAN Alliance demonstrated an array of advancements through various demos, showcasing how AI is increasingly being utilized to optimize and manage network functions. Companies such as Keysight Technologies have made significant strides in this domain. In collaboration with industry giants Samsung and NVIDIA, Keysight showcased the training of AI models designed to bolster Samsung’s current 5G-Advanced infrastructure and its future 6G technologies. One of the notable features highlighted was a model for virtualized RAN software, which promises enhanced network efficiencies.

Furthermore, Keysight extended its AI-RAN orchestration testing through a strategic partnership with Northeastern University. This collaboration aims to explore new dimensions in network management and integration. Collectively, these advancements underline the growing importance of artificial intelligence in optimizing network infrastructure, enabling operators to improve both performance and reliability. As AI continues its rapid integration into RAN, it paves the way for future technological breakthroughs in the telecom industry.

Open RAN

Another cornerstone of MWC 2025 was the expansion and evolution of Open Radio Access Networks (Open RAN). The O-RAN Alliance led the charge with more than twenty demonstrations, each focusing on different facets of open network architectures. A significant contributor to this narrative was Viavi Solutions, which emphasized the imperative of developing optimized and secure network frameworks. These frameworks are set to integrate AI, 6G, and cloud technologies, thereby maximizing the return on investment for telecom operators.

In a bid to further Open RAN development, Viavi Solutions has initiated a partnership with AT&T and Verizon. This collaboration aims to implement the Viavi Automated Lab-as-a-Service for Open RAN (VALOR) as part of the Acceleration of Compatibility and Commercialization for Open RAN Deployments (ACCoRD) project. The project plans to establish testing labs at prominent universities such as Iowa State University, Rutgers University, and the University of Texas at Dallas by 2026. These labs will offer comprehensive testing solutions, thereby propelling Open RAN technologies towards broader commercialization and deployment.

Non-Terrestrial Networks (NTN)

Non-Terrestrial Networks (NTN) have also captured significant attention at MWC 2025, reflecting a growing interest in satellite-based communication. Notably, T-Mobile US has successfully launched its beta satellite service in alignment with Starlink, while AST SpaceMobile has deployed its first series of Bluebird satellites with support from industry leaders AT&T and Verizon. These collaborative efforts highlight considerable advancements in satellite-based technology and signal a new era of reliable and wide-reaching communication capabilities.

Throughout the congress, several demonstrations focused on progressive NTN testing solutions, reinforcing the importance of continuous innovation in satellite communications. The strides made in this area underscore a promising future for NTN, emphasizing its critical role in expanding connectivity coverage in remote and underserved regions. Moving forward, the focus remains on enhancing the robustness and efficiency of satellite communication systems, aiming to solidify their integration within the broader telecom ecosystem.

Supporting Test Developments

In addition to the prominent themes of AI-RAN, Open RAN, and NTN, MWC 2025 also shone a spotlight on pivotal advancements in the test and measurement sector. Anritsu, for instance, showcased its Radio Communication Test Station MT8000A. This new technology is set to assist South Korean operator SK Telecom and Pohang University of Science and Technology in developing real-time optimization technologies for antenna systems using AI. Such innovations are anticipated to significantly enhance data transmission speeds and overall network efficiency.

Another noteworthy collaboration emerged between Infovista and Google Cloud. This partnership is designed to leverage Google’s expertise in network planning to streamline wireless network optimization processes. The collaboration is especially critical in areas such as CBRS deployments, Fixed Wireless Access rollouts, and the expanding domain of private networks. By harnessing advanced testing and measurement techniques, these initiatives aim to provide operators with the tools necessary to develop more efficient and reliable wireless networks.

Strategic Partnerships and Future Outlook

Strategic partnerships and collaborative projects emerged as a recurring theme at MWC 2025, reflecting the industry’s move towards more integrated and cooperative development models. The partnership between Viavi Solutions, AT&T, and Verizon for the VALOR project exemplifies the trend towards collaborative innovation. Such initiatives are essential for accelerating the development and commercialization of new technologies, ensuring that they are optimized and ready for broad deployment.

Looking ahead, the advancements showcased at this year’s congress point towards a future where AI integration in RAN becomes the norm, satellite communications become more sophisticated, and Open RAN frameworks gain broader acceptance. Each of these developments represents a significant leap forward for the telecom industry, promising to deliver faster, more efficient, and more reliable communication solutions.
