Radisys Unveils Industry First 3GPP Release 19 5G-Advanced RAN Software

DALLAS, Texas - February 27, 2026 - Radisys^® Corporation, a global leader of open telecom solutions, today announced the availability of its 3GPP Release 19-compliant 5G-Advanced Connect RAN software suite, setting a new benchmark for ubiquitous connectivity. The next-generation software converges Terrestrial Networks (TN) and Non-Terrestrial Networks (NTN) with integrated AI-RAN capabilities, delivering high performance and scalability across a broad, multi-vendor ecosystem of hardware platforms/achitectures, PHY providers, and O-RU partners. The solution reduces deployment complexity, accelerates time-to-market, and empowers service providers and enterprises to innovate seamlessly across TN and NTN domains.

Radisys' 5G-Advanced Connect RAN software suite establishes a strong foundation for seamless evolution towards future 3GPP releases for B5G/6G, while maintaining full backward compatibility with 3GPP Release 18. This ramp to the future enables scalable, high-performance deployments across NTN/TN, FWA, small cells, private 5G, defence and tactical communications.

Key Capabilities

• Non-Terrestrial Networks (NTN)
  • Support for transparent and regenerative payload modes for GEO, MEO, (V)LEO, and HAPS deployment
  • Multi-band support (S, L, Ku, Ka) for FR1/FR2 FDD
  • Supports standalone or dual-mode NB-IoT NTN (in-band/guard-band)
  • Supports TN-NTN Integration
• AI-RAN
  
  • Enables AI-assisted RAN use cases through seamless integration with xApps, rApps, dApps, cloud-native applications, and vendor-specific solutions
  • Introduces Radisys' Common Layer for AI/ML (CLAIM) Framework, enabling evolution towards the Intelligence Stratum (IS) for B5G/6G Native AI-RAN.
  • Evolution towards ISAC through vendor-specific AI-driven applications, unlocking real-time environmental awareness, analytics, and intelligent network optimization.
• Massive MIMO - Enables Massive MIMO to scale 5G networks with higher capacity, wider coverage, and improved efficiency to meet the demands of mobile broadband.
• Time-Sensitive Networks - Enables advanced 5G URLLC and TSN capabilities to power ultra-low-latency use cases, including industrial automation, autonomous systems, smart grids, and immersive AR/VR experiences.
• Simultaneous Multi-Access & Interoperability - Integrates CBRS, Wi-Fi, and legacy satcom via the Multi Non-3GPP Access Gateway, with N3IWF and AGF support for unified 5G access.
• Concurrent eMBB-RedCap Enablement - Enables a single network to deliver ultra-fast broadband and efficient RedCap connectivity for emerging IoT and enterprise use cases.
• Diverse Deployment Architectures - Leverages Radisys' compact, low footprint Small Cells and 5GCN with flexible deployment combinations targeting Network-in-a-Radio to Outdoor Pico/Micro Cell and indoor femtocells with evolution towards local breakout with co-located UPF.

"By expanding Radisys Connect RAN portfolio with Release 19 capabilities with a strong focus on NTN and AI-RAN, our industry-leading software remains at the forefront of 5G innovation while paving the path towards 6G," said Munish Chhabra, Wireless SVP and General Manager at Radisys. "By combining our multi-platform 5G-Advanced software with Radisys' unique hyper-collaborative co-engineering model, we are empowering our customers to deliver innovative, differentiated, and future-ready 5G solutions to MNOs, SNOs, enterprises, and industries."
