xMASS — Synchronized Massive MIMO SDR Platform
xMASS is a modular synchronized SDR platform designed for coherent RF acquisition, distributed wireless experimentation, beamforming, and massive MIMO infrastructure.
Built around four synchronized xSDR modules, xMASS provides scalable multi-channel SDR deployment with deterministic timing, FPGA-accelerated processing, and distributed RF workflows across compact SDR arrays.
Its modular architecture enables synchronized 8×8 MIMO operation while allowing flexible bifurcation into independent 4×4 and 2×2 SDR subsystems for scalable wireless infrastructure, spectrum monitoring, and RF sensing applications.
Why xMASS
xMASS combines synchronized SDR nodes, FPGA-accelerated processing, and deterministic timing infrastructure into a scalable RF platform for coherent acquisition, beamforming, and distributed wireless experimentation. The modular architecture enables compact synchronized SDR deployment while supporting scalable MIMO workflows, distributed sensing systems, and real-time RF experimentation.
