DIRECT TO PHASE II: Ultra-Low Latency Technology for Radio Applications 5G

SBIR · Phase: BOTH · Topic DON27BZ02-DV027 · Solicitation 27.BZ

Modern C3 operations increasingly depend on commercial 5G and IP-based network infrastructures, which are vulnerable to latency, jitter, packet loss, and adversarial interference. As highlighted in recent industry consensus on how 5G technology is going to transform the Department of War (DoW) [Ref 2], in contested and congested environments, these challenges jeopardize mission-critical data flows, particularly time-sensitive audio communications essential for tactical decision-making. While the Multifunctional Information Distribution System (MIDS) Joint Tactical Radio System (JTRS) is the current standard for secure, jam-resistant tactical data links, it must be modernized to interoperate with these evolving network environments. To maintain a strategic advantage in alignment with the National Defense Strategy (NDS), the Department of Defense Private 5G Deployment Strategy [Ref 1], and Joint All-Domain Command and Control (JADC2) initiatives, the Navy seeks to design, develop, and prototype a software-only solution for ultra-low latency audio data obscuration. This technology must be tailored for IP-based communications operating across 5G and Open Radio Access Network (O-RAN) environments and be seamlessly integrable into existing MIDS JTRS platforms. These software-only innovations will strengthen C3 links in real-time operational scenarios, drawing technical parallels from critical commercial capabilities such as ultra-reliable low-latency 5G for industrial automation [Ref 3] to support high-precision activities including cooperative motion control, video-guided remote operations, and node-to-node tactical communications. By integrating these technologies into existing communication infrastructures, the DoW aims to ensure robust, secure, and resilient communication channels, even in congested spectrum environments or under adversarial jamming and electronic interference. The proposed solution should: Achieve Ultra-Low Latency Audio Transmission: Develop software-based obscuration methods capable of delivering secure, intelligible audio over IP-based 5G networks. The threshold goal is an end-to-end latency of under 20 milliseconds, with an objective goal of 1 millisecond to meet JADC2 and NDS real-time operational requirements. Enhance Resilience in Contested Environments: Ensure audio data integrity and communication continuity in environments affected by spectrum congestion, electromagnetic interference, or intentional jamming, using robust data hiding and spread-spectrum techniques. To satisfy PMO requirements, system resilience and audio intelligibility must be demonstrated and verified against the following representative operational profiles: • 1. Network Packet Loss Resilience: The software-based recovery and reconstruction algorithms must maintain communication continuity under severe channel degradation: • Threshold Target: Maintain continuous link and zero audio stream dropouts under a continuous random packet loss profile of up to 10%. • Objective Target: Maintain link alignment and intelligibility under burst/consecutive packet loss profiles of up to 30%. • 2. Spectrum Congestion Performance: Under simulated high-traffic 5G slice congestion (congested multi-user IP environments): • Threshold Target: End-to-end processing and transmission latency must remain under 20 milliseconds. • Objective Target: End-to-end processing and transmission latency must remain under 1 millisecond. • 3. Jamming and Interference Immunity: The spread-spectrum and data-hiding layers must resist intentional electromagnetic interference: • Threshold Target: Maintain link stability and synchronization under narrow-band and barrage jamming up to a Jamming-to-Signal (J/S) ratio of 15 dB. • Objective Target: Maintain link stability under dynamic tracking jamming up to a J/S ratio of 30 dB. • 4. Audio Intelligibility Standards: Restored and unobscured audio streams must meet standard military voice intelligibility baselines: • Threshold Tar…
