EVOIA Assure

Service Assurance for Critical Communication Networks

The leading solution to monitor and troubleshoot mission critical communications (MCx) and railway telecom networks with confidence. Because failure is not an option.
EVOIA Assure

At VIAVI, we understand that ensuring reliable, secure, and high-quality communications is vital in mission critical environments. Downtime or degraded service in public safety, transportation, utilities, or airports can have real-world consequences.

That’s why EVOIA Assure was designed: to give operators the visibility and tools they need to guarantee performance, reliability, and safety 24/7.

Our expertise spans every layer of mission critical communications (MCx), from application services (MCPTT, MCVideo, MCData) to telecom infrastructure and device interoperability.

EVOIA Assure

Because EVOIA Assure provides full end-to-end monitoring, it is simple to track KPIs, validate SLAs, and resolve issues before they escalate.

And with guaranteed support for GSM-R until 2040 and readiness for FRMCS and beyond, EVOIA Assure protects today’s networks while ensuring a smooth path into the future.

EVOIA Assure is continuously refined based on operator feedback, ensuring new features, metrics, and analysis methods evolve alongside industry needs.

Radio and QoS KPIs

EVOIA Assure provides deep tracing and measurement of key radio and quality of service (QoS) indicators, from handover performance and voice group calls to transaction times and HDLC frame analysis.

This includes real subscriber MCPTT and MCVideo MOS scores. Metrics are available in real time 24/7 with historical access for auditing, compliance, and trend analysis.

EVOIA Assure in Daily Operations

For day-to-day operations, EVOIA Assure acts as a mission critical safety net. It reduces incident resolution time, enables proactive maintenance, and empowers technical teams with actionable insights for optimizing network performance.

EVOIA Assure for Network Acceptance

During rollout and upgrades, EVOIA Assure validates networks against technical KPIs (connection times, transaction success rates, handovers) and functional KPIs (location-based call routing, registration/deregistration, group call area functions). This ensures compliance with safety, performance, and regulatory standards.
