[Communications] - COMIT - Viettel: Developing Radio Frequency (RF) Testing Solution for Viettel’s Worldwide Networks

- Problem: Monitoring radio frequency (RF) signal deviation without stopping base stations. The shutdown of base stations would impact to QoS significantly and take time as huge number of base stations.

- Solution: Engineers of COMIT and Viavi developed a solution that was based on Viavi CellAdvisor and with new features: i) to test RF signal via air interface and 3GPP TS 25.141 standard; ii) to store multiple test results.

- Results: The solution helped Viettel save time and costs in testing its thousands of base stations in Vietnam and is also applied in other Viettel networks.
