Viettel, a Vietnamese multinational telecommunications company based in Hanoi, has deployed the Oscilloquartz timing solution from ADVA, a company focused on advancing next-generation communications networks, throughout Laos and Myanmar.
The solution will, ADVA says, help Viettel to provide nationwide 4G services and prepare its synchronization network for 5G, enabling Viettel to smoothly transition its legacy timing infrastructure, deliver 4G coverage to more mobile subscribers and lay the foundations for next-generation services.
Installed and maintained by NEC, the new solution is built on ADVA’s OSA 3230B primary reference caesium clock (PRC) for assured and precise synchronization with or without global navigation satellite system (GNSS). It also features ADVA’s versatile ultra-compact synchronization supply units (SSUs) with high-capacity PTP modules for what the company calls grandmaster clock functionality.
Viettel’s new solution leverages the OSA 3230B PRC, a high-performance caesium time source that, ADVA says, offers superior accuracy and stability together with operational simplicity and unrivalled flexibility.
Also key to the deployment were ADVA’s Oscilloquartz SSUs, which enable Viettel to maintain its legacy synchronization networks and evolve ultra-precise, highly reliable timing to meet the requirements of time-sensitive applications and 5G connectivity.
All elements of the new timing solution are overseen from Viettel’s headquarters in Vietnam using ADVA’s Ensemble Controller with Sync Director.
