To enable 5G in PTP networks every node must be PTP enabled with Full Timing Support which can lead to costly upgrades and even replacement of existing network equipment which results in high costs and often lock the operator into a single vendor.
The biggest challenge delivering time and phase in a network is handling the asymmetries that occur in the network. Frequency synchronization are not affected by asymmetries i.e. different latencies in the uplink compared to the downlink. This means that there will be hidden asymmetries in the network until phase and time are enabled. For time and phase however, network asymmetries generate constant time error.
Signals in GNSS systems are vulnerable as it i easy to intrude via disruption jamming, either by blocking them out completely (“jamming”) or by replacing the GPS signal with a similar false signal that are stronger than the real signal and provide recipients with the wrong position and time (“spoofing”).
With the current geopolitical situation, the awareness of GNSS jamming and/or possible spoofing has become even more obvious. It’s been increasingly obvious to Mobile operators that GNSS timing cannot any longer be the only source of timing to the critical infrastructure that a Mobile Network constitute. Most network operators are looking to introduce GNSS independent timing in the networks or at least introduce GNSS independent timing as backup in the networks when the GNSS timing is jammed, spoofed or otherwise unavailable.
Mobile operators often have heterogenous networks and it is common with leased lines from various wholesales operators. For PTP networks these leased lines must have full network update to support full on-path synchronization in 5G but since mobile operators doesn’t own the lines it can delay the roll out process or severely restrict the availible offers for capacity services.
Open and disaggregated:
Proven interoperability: Precision TimeNet could be used as Primary or Complimentary synchronization with proven interoperability with base stations and routers from Nokia, Ericsson, Cisco, ZTE and Huawei. Full PTP functionality developed together with Meinberg.
Ensures better uptime of critical 5G services: Enhanced multilink and redundancy options improves stability and redundancy in the synchronization network.
High reliability and stability: The base technology has been used for GPS-independent time synchronization in 20 national digital TV networks since 10 years and Net Insight holds 9 patent families related to synchronization in IP and 5G networks.
Ability to deploy over existing core and aggregation networks including leased lines which significantly reduces rollout time and cost to rural and regional areas as no forklift upgrades are required
PTN is independent on infrastructure and vendors and can be used standalone or as backup/complement to existing sync solution. Timing is independent of network capacity and network layers
By being GNSS independent
High Accuracy timing transfer
High accuracy with Multilink Collaborative Clocks and Dynamic adaption of timestamp streaming
