Synchronisation Arrangement TRIZ Cases
- Cellular Base Station Beacon Synchronization in Low-Coverage Cells
Orthogonal Walsh-Hadamard beacon signals let small cells acquire phase synchronization over the air in low coverage without GPS or backhaul upgrades.
- PTP Time Synchronization Validation Over Unreliable Ethernet
Forward and reverse PTP synchronization with validator clocks checks slave clock integrity over switched Ethernet for reliable sensor fusion.
- IED Time Synchronization Handover to Prevent Protection Blockage
A pre-synchronization message alerts IEDs to grandmaster clock changes, preventing protection blockage during redundant time-source handover.
