5G Synchronization
Combining cutting-edge technology and decades of proven expertise Net Insights Precision TimeNet (PTN) solution provides distribution of absolute time with very high accuracy.
CHALLENGES
While 4G is based on Frequency divided (FDD) systems 5G is based on Time Division Duplex (TDD) systems. As a result the time accuracy and phase synchronisation requirements are much higher in 5G networks compared to 4G thus time and phase synchronization is system critical function.
You need fast and cost-efficient solution that optimize the use of existing underlying infrastructure network. You want an open and disaggregated synchronization infrastructure which support previous investments and existing heterogenous network of e.g. various vendors or leased lines in the 5G deployment process.
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
OUR SOLUTIONS
We offer accurate time synchronization for 5G mobile networks over existing IP infrastructure.
Synchronization is system-critical function in 5G and operators are looking for the best roll out process without comprimizing on quality or reliability. Existing solutions create operational complexity as entire underlying networks might need to be upgraded or heterogenous networks with leased lines build a dependency on vendors.
GNSS/GPS synchronization is commonly used for synchronizing mobile base stations, but operators are increasingly aware of the threat of jamming and spoofing of GNSS signals and national regulators mandate operators to be GNSS/GPS independent. 5G networks will in contrast to most 3G/4G networks be increasingly used for mission critical services including blue light services but also used for autonomuous cars and realtime industry applications (i.e. ultra reliable and low latency communication, uRLLC). Thus the security and reliability is key to mobile operators.
