3 Viewing UWB tag inventory
The Inventory tab displays a table view that provides information on all tags transmitting UWB in range
of the DartWand.
To receive an accurate list, you need to specify the range of the UWB receiver. The minimum setting (1)
only shows tags within a few inches of the reader. The maximum setting (25) shows tags transmitting
within maximum range; this can be over 500 feet, depending on the environment. For information on the
estimated DartWand UWB range, see Appendix I (on page 25).
The followin
g table describes the table columns available on the I
nventory tab.
