Hi @zjustin06
I would like to add that the TDOA/TWR approach heavily depends on area type. Like for open halls the TDOA can be better for a such big quantity. But if it is like hospital - tons of rooms then TWR will provide much better performance. As there are many rooms then you will have only limited amount of nodes on one place.
I would also expect that those 3000 nodes are on in the same spot but they are spread across the factory so you need to figure out on how many nodes can be in one area.
For example in PANS you can have 15 nodes at 10Hz in one area or 150 nodes in one area with 1Hz update and so on.
Cheers
