NTN applications are beginning to converge with cellular
Keysight Technologies has added updates to its flagship Pathwave design software to support designs for 5G Non-Terrestrial Network (NTN), by enabling architectural digital twins. Keysight says this changes the design flow from one that is hardware-centric to one that is simulation-centric.
“New 5G NTN systems have challenging complexity, which is stressing development lifecycles,” the company explained in a release, adding, “Simulations that use measurement-derived models deliver higher fidelity in mission-critical applications such as satellite communications and aerospace defense. System architects want to explore real-world ‘what if’ scenarios prior to building hardware to reduce technical risk and minimize time-to-market.”
There have been several notable announcements recently that relate to convergence of cellular and satellite-based technologies: For instance, T-Mobile US’ news that it will share spectrum with Starlink and use LEO satellites to provide satellite-based texting; and Apple’s announcement that the iPhone 14 will include satellite connectivity for emergency calls.
“5G applications are evolving towards 6G, requiring the need for tools that address the entire digital engineering design and validation workflow,” said Peter Blood, Keysight’s director of product management for PathWave System Design. “Organizations are demanding that systems are virtually prototyped in their target scenario, so system and mission engineers are turning to simulation, virtual prototyping, and digital twins. These techniques shift the development process left in time and remove the need for multiple physical prototypes. PathWave System Design blends simulation with measurement-derived models and offers a complete RF system workflow to rapidly architect, design, and verify these complex NTN systems with updated 5G libraries.”
