What determines UWB update rate and end-to-end latency?

Answer

Per-tag update rate is how often a new measurement or position is produced for one tag. End-to-end latency also includes transmission, host processing and filtering. The fastest mode is not the default for every product or tag count. For example, the ULM1 manual specifies a 10 ms single-tag cycle at 6.8 Mbps, while the ULM3 manual describes a 12 ms slot at 850 kbps. Use the schedule for the actual model and firmware, then measure application latency under the intended tag count and network load. Do not treat radio data rate in Mbps as a position update rate.
