Why buy four anchors if three anchors can calculate a position?
UWB PositioningAnswer
1) Tags should operate inside the anchor coverage area. Four anchors can cover a rectangular area rather than a triangular one; the source describes an approximately doubled coverage area. 2) Wireless ranging can fail. With four anchors, a position can still be calculated when ranging to at least three succeeds; a three-anchor setup needs all three measurements to succeed. 3) A four-anchor, one-tag setup can be reconfigured as three anchors and two tags to learn multi-tag operation. 4) Four anchors can support 3D positioning when the installation spans length, width and height in a 1:1:1 arrangement.

Communication range varies by module; the source states that nominal accuracy is maintained within its specified coverage range under the applicable conditions.
Specifications and performance
What determines UWB update rate and end-to-end latency?
UWB PositioningAnswer
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.
