Numerous authorities directives such because the Cyber Incident Reporting for Important Infrastructure Act of 2022 (CIRCIA) and the EU’s Important Entities Resilience (CER) Directive mandate enhanced safety for important infrastructure, applied sciences equivalent to non-terrestrial networks (NTNs), positioning, navigation, and timing (PNT) programs, IT structure and area communications. With such directives in impact, the safety, reliability, and efficiency of mission-critical communications has by no means been extra important.
Deploying superior instruments equivalent to digital twins and post-quantum cryptography (PQC) can mitigate dangers, guarantee resilience, and assist compliance. This weblog explores how VIAVI addresses the challenges of mission-critical programs.
NTN Digital Twin Testbed
Many functions – from IoT by to autonomous driving – require exceptionally low latencies and wide-ranging protection. Current years have seen the introduction of Non-Terrestrial Networks (NTNs) to assist these functions, for instance by using Ku-, Ka- and S-band communications to offer net entry in catastrophe restoration situations, in addition to for automotive navigation and in-flight infotainment programs.
Whereas these NTN programs have gotten extra commonplace and micro-launching firms assist scale back some expenditures, the price of launching into house remains to be exceptionally excessive. This excessive price ticket calls for an intensive analysis of each aspect earlier than an NTN launches.
VIAVI and Rohde & Schwarz have partnered to develop an NTN digital twin testbed for LEO (Low Earth Orbit), MEO (medium earth orbit) and GEO (geostationary earth orbit) that may precisely validate end-to-end connectivity, efficiency, reliability and stability with out disrupting stay operations. The digital twin testbed helps within the proactive identification and backbone of potential bottlenecks and vulnerabilities earlier than they come up in situ.
The VIAVI and Rohde & Schwarz NTN testbed helps SKY Excellent JSAT’s just lately unveiled Common NTN Innovation Lab. Launched in November 2024, the NTN Lab will function a testing hub for the belief of the “Common NTN”, a pioneering idea leveraging Geosynchronous Earth Orbit (GEO) and non-GEO satellites, and Excessive-Altitude Platform Stations (HAPS) with expertise that allows computerized routing to the optimum communication path.
Community Synchronization
Correct and safe timing is important for synchronized operations, cryptographic safety, and dependable community efficiency, particularly in mission-critical situations. Positioning, Navigation, and Timing (PNT) companies have develop into indispensable, enabling exact synchronization and coordination throughout varied sectors.
At its core, PNT depends on indicators from world navigation satellite tv for pc programs (GNSS) to supply correct location and timing info. These indicators are important for a variety of functions, from guiding plane and ships to synchronizing monetary transactions and energy grid operations. Nevertheless, the widespread dependence on GNSS indicators additionally exposes important infrastructure to vulnerabilities and dangers, making it prone to disruptions attributable to sign jamming, “spoofing” and different types of interference.
VIAVI’s SecurePNT™ with SecureTimeSM Providers represents a serious development in safeguarding important infrastructure towards the vulnerabilities inherent in conventional GPS and GNSS programs. The answer offers a extremely correct and secure timing reference for PNT synchronization, making certain resilience towards exterior threats.
Spectrum Optimization
Environment friendly use of the Radio Frequency (RF) spectrum is essential for dealing with simultaneous important companies in congested or emergency situations. Spectrum optimization enhances capability and minimizes interference, enabling dependable communication even in probably the most difficult environments.
VIAVI’s OneAdvisor 800 is a flexible resolution designed to optimize spectrum utilization. Actual-time insights into frequency utilization, in addition to proactive identification and backbone of sign conflicts assist forestall interference. The OneAdvisor 800 empowers community operators to maximise efficiency and keep service high quality in high-demand situations.
Assurance Monitoring
As networks develop more and more complicated, real-time monitoring of efficiency, safety, and repair high quality turns into important. Assurance monitoring permits operators to determine and handle points earlier than they escalate, making certain uninterrupted community operations.
VIAVI NITRO® AIOps’ AI-driven capabilities serve mission-critical networks by simplifying NOC complexity and streamlining operations. NITRO AIOps is a sophisticated, end-to-end, top-down clever engine that seamlessly integrates throughout multi-vendor, multi-technology and multi-domain environments. It bridges the hole between complicated networks and environment friendly operations – enabling a transformative method that leverages AI, ML, and massive knowledge analytics to automate and improve end-to-end multi-domain community orchestration.
Quantum Communications Testing
We’re coming into a publish quantum cryptography world, with consultants estimating that there’s a greater than 50% probability of quantum computer systems being highly effective sufficient to interrupt normal public-key encryption in lower than 15 years. This implies the programs developed at the moment will probably nonetheless be energetic and builders should take this threat under consideration and develop the following technology of ultra-secure communication strategies.
Introducing cryptographic protocols can create extra community efficiency overhead, which impacts end-user high quality of expertise. VIAVI’s TeraVM Safety Take a look at is trusted by main community safety infrastructure distributors, service suppliers, analysis institutes, governments and enterprises to emulate large-scale person endpoint site visitors functions over safe entry connections whereas measuring particular person site visitors movement efficiency throughout a number of high quality vectors. TeraVM Safety Take a look at validates quantum-safe algorithms and ensures that encryption strategies can stand up to quantum computing assaults.
