OVERVIEW

Requirements for synchronization for 5G mobile operators

Precise time synchronization

Reliable and high accuracy time synchronization in mission critical 5G services

Accelerate 5G Roll out

By deploying over existing underlying infrastructure operators will accelerate the national roll out process

Regulatory requirements

GNSS independency to manage jamming and interference vulnerability while meeting regulatory and service delivery requirements for mission critical applications.

Vendor independent

Vendor independency for heterogenous networks to easily operator complex network with multiple vendors or leased lines

CHALLENGES

Why this is important to you

PTP networks require full on-path HW support

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.

Handling asymmetries

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.

Unreliable due to jamming & spoofing

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”).

Regulators mandate a GNSS independent alternative

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.

Complex heterogenous networks with leased lines

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.

1

Open and disaggregated: Ability to deploy over existing core and aggregation networks including leased lines. Timing is independent of network vendors, network capacity and network layers.

2

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.

3

GNSS independent: GNSS solutions are inherently vulnerable to jamming and spoofing. Regulators, like the Swedish Post and Telecom Authority (PTS) begins to require a GNSS independent solution in the 5G networks.

4

Ensures better uptime of critical 5G services: Enhanced multilink and redundancy options improves stability and redundancy in the synchronization network.

5

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.

BENEFITS

What we can help you solve

Accelerate national 5G roll-outs

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

Independent of underlying infrastructure

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. Core, regional and access separately handled

Higher security and reliability

By being GNSS independent PTN is not vulnerable to jamming and spoofing as there is no need for GNSS at each site for the solution
