Research Overview

The upper mid-band — roughly from 6 to 24 GHz — has attracted considerable recent interest for new wireless services.   Developing systems in these bands presents several challenges including the need to share spectrum with incumbents including communication satellites; operate over a wide bandwidth; and adaptively utilize spatial and bandwidth degrees of freedom.   In this project, NYU is collaborating with NYU start-up Pi-Radio to build a wideband software defined radio (SDR) for experimentation in the upper mid-band to tackle these challenges.

The proposed system has several valuable features for developing spectrally agile wide band systems:

• Support over the full FR3 band (6-24 GHz) with fast band switching and a quad band antenna board.
• Fully digital 8 channel in each band
• Wide bandwidth 1 Gsps per channel
• Embedded logic in the ARM cores for ultra-fast control for spectrum agility
• Interface support for MATLAB, Python, OAI and O-RAN
