Weaver: A System for AI-RAN Compute Sharing with Foundation Model Training

The emergence of AI-RAN infrastructure, which equips cell sites with GPU-accelerated hardware, creates an opportunity to colocate non-RAN workloads with primary RAN processing. We explore using this spare capacity for decentralized training of foundation models (FMs), one of the most compute-intensive AI workloads. We...

Demo: Chronos - A Cloud-based RAN Emulation System

We demonstrate Chronos, a cloud-based RAN emulator that allows running unmodified 4G/5G protocol stack software at large scale over commodity cloud VMs, using OpenAirInterface as the representative vRAN software. Chronos replaces compute-intensive PHY processing at the FAPI boundary, while employing time dilation and s...
