The optimized dual-frequency GNSS receiver on our OSA 5401 achieves excellent performance, even in urban canyons where small cells are often deployed. Generating phenomenal PTP phase and frequency synchronization for traditional base station and small cell network deployments, the technology gives network operators a cost-effective migration path for deploying strong synchronization deep in radio access networks. It also integrates with existing network elements. Its small form factor and rich feature set enable a versatile range of deployment options for enhanced synchronization network performance.
