Granularity/Resolution/Accuracy

Some vendors suggest resolution can be 1-2m　but additional access pointslikely to be required. 5-10　m typically

Can be as low as in inches.

Tracking suitability

Best adopted enterprises already having or planning to implement a Wi-Finetwork as the tagsleverage operations on the same network

Although can be adopted in any enterprise UWB RTLS distinct advantage isenabling a high level of　granularity. It is expected to　flourish in mission critical applications or for　personnel tracking in dangerous environments
