Distributing time sync for mission critical networks

Home » Government


Government and homeland security networks require reliable and secure services, even in challenging environments

The geopolitical situation has made governments and community organizations aware of the strong requirement to build robust and secure infrastructure. A core building block in many of these applications is an accurate time synchronization. During conflicts it has been evident that relying solely on GNSS/GPS services is not secure, since they will be targeted with both jamming and spoofing attacks. A distributed, disaggregated synchronization solution is key to provide a secure and reliable synchronization that also covers challenging and encrypted links. Homeland security services will increasingly use 5G and are contributing to the requirement for a secure and reliable 5G infrastructure where synchronization is a key network capability and enabler of future mission-critical 5G services.


Top 3 challenges we can help you solve

How to increase service security and reliability through GNSS/GPS independence

Conflicts and tense geopolitical situations have made operators aware of the vulnerability of GNSS solutions and that satellite signals are easily jammed or spoofed. Several countries have mandated that all 5G deployments need to be GNSS independent for the operator to receive a license.

How to secure critical service availability

Accurate time needs to be available everywhere in the network and asymmetries and network failures in the underlying infrastructure must not be allowed to interrupt or disturb the timing distribution. Services also need to work seamlessly both in indoor and outdoor environments.

How to enable synchronisation over a network with challenging and encrypted links

Time accuracy and phase synchronisation requirements are much higher in critical networks thus time synchronization is a system critical function with high impact on service performance and delivery. Synchronization needs to be handled independent of underlying infrastructure and should include leased line and SLA support.


Distributing time synchronization through overlay sync network

Net Insight’s synchronization solution Zyntai is designed to address the time synchronization challenges faced by today’s complex networks. Our solution creates an overlay sync network that operates independently of the underlying IP and transport infrastructure. This provides precise time synchronization where it is needed without requiring time sync hardware support in routers, switches and transport nodes, while working also over leased capacity. By distributing time sync over the network, your sites also become independent of external GPS/GNSS sources, reducing vulnerability to interference beyond you own control.

Implementing an overlay network-based synchronization ensures a more reliable network performance, increased control over your synchronization, and faster time sync deployment without the need for extensive hardware upgrades. Our solution empowers you to optimize your network’s efficiency and reliability while minimizing costs.

GNSS independent time sync across 5G network with leased capacity

Three Sweden

Europe – Mobile operator

Three Sweden was tasked with implementing a GPS/GNSS independent time synchronization solution for their nationwide 5G network, a critical requirement set by the Swedish regulator PTS for all 5G licenses. Given that 70% of their base stations rely on leased capacity links, finding a suitable solution posed a significant challenge.

“As a 5G operator with a large share of leased fibre capacity in the aggregation part of the network, it was crucial for us to find a synchronization solution that could work independently of GPS and support our existing transport infrastructure. Net Insight’s solution was the only one in the market that could combine all these specific requirements and enable an extremely cost-efficient, fast, and easy rollout.”

Türk Telekom

Europe – Mobile operator

Türk Telekom has become the first operator in the world to implement the “Time Synchronization Transmission Solution”in corporation with Net Insight. This technology is expected to significantly reduce synchronization investment costs and increase service continuity in 5G.

“We see a significant potential in the global market for this innovative solution that will reduce costs and increase service continuity for mobile operators and all industries with critical time synchronization requirements. We can meet all these needs with this solution, which has a time deviation far below 1500 nano-second required for the synchronization need of 5G.”
