TMYTEK, Taiwan-based wireless technology company, has introduced a new open-source research platform designed to accelerate the development of next-generation wireless technologies. The FR3 OAI Testbed enables advanced experimentation in the FR3 midband spectrum (6–24 GHz) - a frequency range widely referred to as the “golden band” for 6G.
Built for researchers, regulators, and industry innovators, the platform provides a flexible environment for exploring emerging 6G use cases, spectrum coexistence, and AI-driven wireless systems. The FR3 spectrum- ranging from 6 to 24 GHz - has gained attention as a promising band for future 6G networks because it balances coverage, capacity, and performance better than traditional low-band or millimeter-wave frequencies.
TMYTEK’s new platform expands the capabilities of its earlier FR2 OpenAirInterface testbed by enabling real-time testing in the FR3 midband spectrum. The system integrates several key components, including the OAIBOX FR3 stack, the NI Ettus USRP X410 software-defined radio, TMYTEK’s UD Box 0630 RF front-end hardware, and a 6-30 GHz horn antenna. Together, these elements create a comprehensive test environment that allows researchers to conduct real-time experiments across the upper-midband frequency range.
The platform is built around OpenAirInterface, giving researchers full access to the wireless stack for experimentation, protocol development, and system optimization. This open-source architecture provides the flexibility needed for advanced research in next-generation wireless technologies.
Using this approach, researchers can explore and develop advanced capabilities such as AI-driven spectrum sharing, spectrum coexistence modeling, and FR3 waveform testing. The platform also supports integration with other communication technologies, including Fixed Wireless Access (FWA), satellite communications, and microwave systems.
By making previously complex and difficult-to-measure radio environments more accessible, the platform enables research teams to better understand how future wireless networks can operate efficiently in increasingly crowded spectrum environments. Beyond technical experimentation, the FR3 OAI Testbed is designed to support research that can influence future telecommunications standards.
The platform aligns with international initiatives such as IMT-2030, which defines spectrum targets for next-generation networks—including 7.125–8.4 GHz and 14.8–15.35 GHz bands. It is also positioned to support research leading up to discussions at World Radiocommunication Conference 2027.
With this capability, researchers can move from theoretical modeling to real-world testing—helping regulators and industry stakeholders better understand how future 6G systems will operate.
The platform is designed to support both 5G and early 6G experimentation with a flexible architecture that includes:
Its modular architecture allows users to configure components based on specific research needs, including RF front-end modules, filters, and software-defined radio systems.
The FR3 OAI Testbed is designed to support a wide range of stakeholders involved in next-generation wireless technology development. This includes wireless researchers working on new communication protocols, spectrum regulators evaluating midband coexistence models, and 6G innovators developing emerging technologies such as Reconfigurable Intelligent Surfaces (RIS) and Integrated Sensing and Communications (ISAC). The platform is also well suited for universities and research laboratories that require a customizable and reference-grade test environment capable of delivering repeatable research results.
Through the OAIBOX Dashboard, the platform enables rapid configuration of frequency settings, bandwidth, and spectrum hopping. This simplified setup allows researchers to conduct complex wireless experiments efficiently without the need for extensive scripting or complicated system configuration.
As global research efforts intensify around 6G, platforms like the FR3 OAI Testbed aim to shorten the gap between early-stage research and real-world deployment. By providing an open, customizable environment for midband experimentation, TMYTEK’s FR3 testbed gives researchers the tools to explore the technologies, spectrum strategies, and architectures that will shape the next generation of wireless networks.
