Swisscom delivers exceptional HD voice quality with VoLTE

Solution

EXFO’s VoLTE service assurance solution, consisting of Nova Geo for geolocated RF optimization and Nova Core for end-to-end troubleshooting, has been deployed to monitor Swisscom’s network. The solution is being used by Swisscom’s radio and troubleshooting  engineers and an on-site EXFO expert.

EXFO accompanied Swisscom during the pre-VoLTE launch phase with their network preparation (RF optimization and troubleshooting). Now that the service is fully up and running, EXFO’s experts are performing on-going quality performance assessments and optimization tasks, including troubleshooting of VoLTE issues, SRVCC failures or intra-LTE handover errors. They also monitor closely VoLTE subscribers to detect areas with specific VoLTE issues or VoLTE compatible devices that do not perform well.
