Core Insights - Keysight Technologies will demonstrate lab-based validation of new radio non-terrestrial networks (NR-NTN) devices in collaboration with Samsung Electronics at Mobile World Congress 2026, focusing on Low Earth Orbit (LEO) satellite deployments, including Starlink Direct to Cell [1][2] Group 1: Industry Context - Satellite connectivity is becoming essential for the evolution of 5G and future 6G networks, necessitating early validation of NR-NTN performance by chipset and device vendors before large-scale deployment [2] - LEO satellite systems present unique challenges such as rapid motion, frequent handovers, dynamic link conditions, and stringent positioning requirements, which require accurate laboratory methods for performance assessment [2] Group 2: Technology and Solutions - Keysight's NTN Network Emulator Solutions simulate LEO satellite characteristics in a controlled lab environment, integrating a 5G Network Emulator with a Samsung NR-NTN modem to validate mobility, service continuity, and higher-throughput MIMO configurations [3] - The demonstration will also highlight Keysight's positioning emulation capabilities, enhanced by its recent acquisition of Spirent, enabling accurate global navigation satellite system-based positioning [4] Group 3: Executive Insights - Samsung's Executive Vice President emphasized that NR-NTN introduces technical challenges for modem design, and the collaboration with Keysight is crucial for validating modem performance under satellite conditions [5] - Keysight's Vice President noted that the transition from concept to deployment for direct-to-device satellite connectivity makes early end-to-end NR-NTN validation essential, providing a repeatable method to ensure interoperability and performance [5]

Market Overview - U.S. equities reached new all-time highs, with the S&P 500 and Nasdaq both extending their December rally, driven by easing inflation expectations, stable yields, and strength in mega-cap technology [2] - The upward movement reflects improving risk appetite, lighter positioning into year-end, and growing confidence that monetary policy will not be a headwind heading into 2025 [3] Company Developments - AST SpaceMobile successfully launched its BlueBird-6 satellite, marking a significant milestone in its direct-to-device satellite connectivity roadmap, with initial systems checks indicating nominal performance [4] - The successful launch de-risks execution for AST SpaceMobile and strengthens its position as one of the few companies pursuing space-based cellular broadband at scale, reinforcing long-term confidence in its constellation buildout [5] Trading Environment - The upcoming holiday schedule indicates a shortened trading week, with U.S. markets closed on Christmas Day, leading to thin liquidity and exaggerated market moves [6] - Most investors are focused on managing risk rather than initiating new positions, with the final days of the year centered on protecting gains rather than chasing them [6]
