Collaboration with NVIDIA for 5G+ Wireless Technologies
Communications and Signal Processing Research Laboratory (HİSAR Lab) at TÜBİTAK BİLGEM collaborates with NVIDIA using Aerial Research Cloud (ARC) platform as an early adopter for beyond 5G wireless technologies. The NVIDIA ARC platform will be a game changer in next generation wireless technology research by offering researchers a fast prototyping environment to demonstrate their research ideas. This collaboration focuses on innovative areas such as Reconfigurable Intelligent Surfaces (RIS), distributed cell-free massive MIMO, millimeter wave hybrid beamforming, and telco cloud solutions.
TÜBİTAK BİLGEM has established an end-to-end private 5G network supporting commercial phones using Aerial Research Cloud which is open source at all layers. With this platform, collaborative work with universities will facilitate the transfer of academic knowledge to industry and the training of young researchers. TÜBİTAK BİLGEM will act as a bridge between industry and academia by developing pre-commercial technologies in collaboration with universities, aiming to stimulate the 5G/6G ecosystem.
xApps Integration with NVIDIA ARC-OTA for Optimizing RIS-assisted Wireless Communication System
Reconfigurable Intelligent Surfaces (RIS) have emerged as a key breakthrough for next-generation wireless networks. Despite numerous theoretical studies on RIS, real-life demonstrations remain limited. HİSAR Lab is addressing this gap by implementing RIS in an end-to-end Open RAN network, leveraging the NVIDIA Aerial Research Cloud platform. This setup includes over-the-air experiments with an open-source full-stack 5G system, a RAN Intelligent Controller, and RIS deployment.
The GPU-centric implementation of this platform aligns perfectly with our research goals, as AI/ML algorithms will optimize RIS configuration under varying network conditions. The Aerial Data Lake, along with the NVIDIA pyAerial library, will play a crucial role in collecting RF samples from the 7.2x fronthaul interface.
