Mission-Critical Communications at Mobile World Congress
March sees the return of Mobile World Congress (MWC) Barcelona, and mission-critical communications is set to be a key theme at VIAVI’s booth 5B18.
In every generation of mobile communications, VIAVI has been a trusted partner helping the ecosystem prepare for and validate the path forward. As we approach the AI-driven evolution from 5G to 6G, the industry is moving not only forward but also outward and upward.
The communication network is now the foundation of an expanding array of application-specific networks, from satellite to MCx to private, each of which must be tested, monitored, assured, optimized and secured. Only VIAVI has the comprehensive portfolio of Wireless, NTN, assured Positioning, Navigation and Timing (APNT), MCx and private network solutions to enable reliable communication and operation across these environments.
At MWC Barcelona 2026, VIAVI will be shining a light on the technology and the fail-safes that ensure that there is no room for error, including expanded satellite constellations that complement terrestrial systems for maximum coverage and uptime. Many national public safety networks, critical infrastructure and industrial private networks have turned time and again to VIAVI for monitoring and assurance across terrestrial and Non-Terrestrial Networks (NTN) communications, as well as for SecureTime-based APNT services.
A Trusted Partner
VIAVI is trusted by countless organizations to help ensure networks are validated to go beyond simple reliability. Our demonstrations at MWC Barcelona 2026 will cover the network lifecycle from planning and lab validation to field deployment to operations and optimization.
VIAVI’s booth 5B18 will house five mission-critical communication demos with meetings available both at the show and on request. Book a demonstration today.
NTN Testing
Discover how the complete VIAVI suite enables you to overcome the technical challenges related to 5G NTN, and provide the assurances to guarantee new NTN constellations perform reliably and conform to 3GPP Release 18 and beyond. Our experts will highlight how you can evaluate networks via a digital twin, test real gNodeBs and User Equipment (UE), and confidently deploy with OTA test (in orbit).
Wireless Field Test
The OneAdvisor 800 provides end-to-end RAN validation across deployment, operation and optimization phases. During deployment, it verifies coaxial and fiber infrastructure integrity and validates Open RAN Radio Units (RUs).
In operational environments, the OneAdvisor 800 enables OTA radio verification, including for radio synchronization and RF interference visualization with the new RF Viewer augmented reality (AR) solution. For optimization, it delivers Multi-RAT radio coverage assessment for 4G, 5G, and NTN. In addition, an AI Expert with wireless domain expertise provides contextual user assistance and enables natural-language-driven test automation for OneAdvisor 800 measurement workflows.
Secure PNT and Synchronization
The GPS and GNSS signals that the world’s essential networks rely on are being compromised on a daily basis. VIAVI’s SecurePNT and SecureTime offer the industry’s most resilient PNT, with multisource assurance combining signals from GNSS-dependent government and GNSS-independent commercial constellations across MEO, GEO and LEO. VIAVI’s new patent-pending Cesium-less holdover solution will also be on display for the first time at MWC Barcelona 2026. More information about this new solution will be available soon.
MCx Service Assurance
VIAVI’s EVOIA Assure addresses the operational challenges of mission-critical communications, where continuous availability, predictable performance, and safety are mandatory.
Arguably, one of the biggest challenges faced by MCx operators is the lack of end-to-end visibility across complex environments, which will often include MCx, Tetra-MCx IWF, 4G and/or 5G. This complexity makes it difficult to quickly detect issues, assess service quality, and maintain operational confidence across mission-critical services (MCPTT, MCVideo, MCData), telecom infrastructure, and device interoperability.
At MWC Barcelona 2026, see how VIAVI addresses these challenges to meet the needs of a wide array of sectors, be it for public safety radios, port operations, mining, transportation (including rail networks) and other critical network environments where communication failures are not an option.
Private Networks Edge Monitoring
VIAVI’s XEdge has been designed to revolutionize service level agreement (SLA) monitoring. By incorporating advanced edge computing, a centralized cloud dashboard, and AI analytics, XEdge provides businesses with the tools to ensure network services meet or exceed agreed-upon standards, all while simplifying the complexities traditionally associated with radio network management.
Our demonstrations at MWC Barcelona 2026 will show how the platform has been expanded to integrate new sensors including XEdge v2 and XEdge Lite that strengthen data collection capabilities for private 4G, 5G and Wi-Fi networks at the edge.
VIAVI at MWC Barcelona 2026
In addition to the above Mission-Critical Communications demonstrations, VIAVI will showcase its latest solutions for security and quantum-safe networks, AI Data centers, AI Operations, and the shift to 6G and the AI-RAN.
