Railway and MCx Assurance

Test, measure & monitor telecom networks & mission critical systems performance with confidence

Railway and MCx Assurance

VIAVI Solutions provide market-leading tools specifically for railway and other mission critical operators using 2G, 3G, GSM-R, 4G, 5G and FRMCS networks. As well as transportation (railways, airports, and harbours), the Emergency services, power plants, offshore platforms, factories, hospitals, and mining operations, are all embracing the new generation of Mission Critical Services (MCS) networks.  

The greater flexibility and local broadband access these networks offer, allows organizations to improve their efficiency, reactivity and service quality, thanks to new applications and usages. 
However, because mission critical private networks are technically demanding environments, their operators depend on them to run securely, efficiently, and effectively.

That’s why our EVOIA portfolio includes the most-used railway telecoms and signalling, test, measurement and monitoring solutions in the rail industry. It is also why VIAVI already supports railway and other mission critical operators in over 30 countries across Europe, Africa, Middle East, and Oceania.


The name EVOIA is derived from the Greek word ‘Evvoia’, meaning ‘sense’, and stands for Enhanced Visibility, Optimization, Investigation & Assurance. 
The EVOIA portfolio brings together several VIAVI solutions, including:

  • QATS Railway telecoms and Signalling solutions, previously offered by Expandium
  • NetProbe Drive Test railway solutions, previously offered by Comtest Wireless
  • Cybersecurity solutions for Operational Technology
  • New MCx monitoring solutions
