Upper Mid-Band (FR3) Measurement Testbed at NYU WIRELESS (2024)

This project presents a near-field measurement system for upper mid-band (FR3) frequencies (6-24 GHz) to support next-generation mobile networks. The platform captures MIMO channel parameters at various displacements using a combination of Vivaldi antennas, a Pi-Radio FR3 transceiver system, and an RFSoC 4x2 baseband system using Xilinx Zynq subsystem. The system enables accurate measurement of near-field propagation by recovering paths and spherical characteristics, overcoming the limitations of traditional plane wave approximations in channel modeling.
