Software-defined radios (SDRs) are the most fundamental tool needed by wireless researchers. They are as fundamental as computers are to computer engineers, or pianos are to pianists. However, the market for SDRs is limited to traditional bands and technologies, and modern wireless technology has moved well beyond the capabilities offered by mainstream SDRs. New frequency bands present new challenges to overcome, and Pi-Radio provides the SDRs that can help researchers in these new bands above 6GHz.
As we transition from the 5G world into 6G, we look into using the frequencies between 6 and 24GHz, where spectral coexistence and more complex propagation models offer opportunities and challenges for researchers to approach. On the other hand, millimeter wave (mmWave) frequencies offer a number of advantages for short range communications and sensing, opening frontiers in robotics, autonomous vehicles and AR/VR/XR.
Pi-Radio offers a number of software defined radios that enable research and development in these new frequency bands, from 6GHz to 140GHz. By using a SDR in a real world environment, the accuracy of simulation can be tested and validated. Real world use cases can be evaluated and problems not identified in simulation can be found early in the development phase by field testing.
In addition, we offer SDRs with fully-digital beamforming, allowing for simultaneous multi-lobe beam patterns that are computed with O(1) complexity. This means channel sounding can be conducted with information on the angle-of-arrival, and multiple paths can be tested at once.
Simply put, wireless research needs real-world experimentation to solve the increasing challenges of tomorrow. Pi-Radio provides the tools you need to do it.
Pi-Radio is a spin-off supported by the New York State Center for Advanced Technologies in Telecommunications (CATT) located in the Tandon School of Engineering at New York University. Pi-Radio has been funded by the NSF STTR and the ARMY STTR programs. Early developmental efforts have been supported by NIST.
