TMYTEK has introduced a mmWave ISAC validation platform, developed in collaboration with NI Ettus, to support research on Integrated Sensing and Communication (ISAC) technologies for next-generation 6G networks. When combined with TMYTEK's BBox 8×8 Duo 28 GHz phased array beamformer, the NI Ettus USRP X410 software-defined radio provides a turnkey environment for mmWave ISAC prototyping and validation. Designed to simplify RF hardware integration, the solution enables researchers to concentrate on waveform development, beamforming techniques, and sensing algorithm verification instead of complex system setup.
Integrated Sensing and Communication is expected to play a significant role in future wireless networks by allowing a single infrastructure element to simultaneously transmit communication signals while performing radar sensing. This approach enables applications that require both high-speed data transmission and environmental awareness, including autonomous systems, industrial automation, and intelligent transportation. However, implementing ISAC at mmWave frequencies requires overcoming challenges related to bandwidth, beamforming, output power, and RF hardware integration.
One of the primary challenges in mmWave ISAC development is balancing high-bandwidth communication with accurate sensing performance. The joint platform addresses this by integrating a 64-channel IF-ready phased array beamformer capable of delivering up to 400 MHz instantaneous bandwidth while maintaining a commercial-grade error vector magnitude (EVM) floor of -32 dB across validated operating distances between 0.5 and 3.5 meters.
The system also supports dynamic two-dimensional beam scanning across ±60 degrees in azimuth and ±30 degrees in elevation. This capability allows researchers to distinguish multiple closely spaced targets with centimeter-level ranging accuracy while maintaining reliable communication links, making the platform suitable for evaluating both sensing and communication performance within a unified test environment.
To accommodate different research requirements, TMYTEK offers flexible hardware configurations. The all-in-one BBox 8×8 Duo can be deployed as a standalone solution, while alternative configurations pair the company's UD Box with either the 16-channel BBox One or the 4-channel BBox Lite beamformers. These options allow research teams to scale their testbeds according to project scope and deployment objectives.
Beyond the hardware, the platform incorporates open APIs and integration with the NI-USRP LabVIEW Reference Architecture. Researchers gain access to transmit reference waveforms and synchronized receive echo data, while automated transmit power compensation and receive automatic gain control reduce the need for manual RF calibration. This architecture supports the implementation of advanced sensing algorithms such as MUSIC, ESPRIT, and compressed sensing, helping accelerate the transition from simulation to hardware validation.
The validation platform is compatible with multiple hardware configurations, including PXI-based and standard PC-based systems using the NI Ettus USRP X410 as the host platform. Supporting components include TMYTEK's phased array antennas, frequency up/down converters, and configurable data interface options, allowing researchers to tailor the system for specific ISAC deployment scenarios.
According to TMYTEK, the joint validation platform is intended to bridge its mmWave RF front-end technologies with the NI USRP ecosystem, providing a system-level environment for ISAC prototyping. By simplifying hardware integration while maintaining flexibility for custom algorithm development, the solution aims to support research teams working to advance next-generation 6G communication and sensing technologies.
