RTLS Synchronization Layers
To understand RTLS System synchronization, it is important to have a look on the RTLS System layer model. On the picture below, you can see the layer model of RTLS model:
It defines Anchor network connectivity on the bottom, and goes up throught UWB and TDMA Synchronization, to features like True Location or Presence Detection, up to API as the Top Layer.
Synchronization refers to the bottom three layers, those 3 layers represent the Synchronization Layer Model:
- Ethernet - Network Connectivity
Provides fundamental connectivity via Ethernet or Wi-Fi backhaul from RTLS Studio to Anchors.
- TDMA - Slot Aligment
Provides Time-Division Multiple Access for Anchors via TCP in microsecond (μs). TDMA sync allows to reorder, shrink and expand time-slots, which provide robust and optimal synchronization for installation with lot of Masters.
- UWB - Time Synchronization
Provides sub-nanosecond (ns) UWB synchronization for positioning among anchors.
The key layers for synchronization are:
