Ubisense – Ultra-wideband In-Building Location System – Ubitag V1.0

Troubleshooting

The activity of the LEDs on the Ubitag may be used to diagnose potential problems with the

device:

• Periodic, short (less than 1/10

second) flashes of the green LED indicate that the tag is

in communication with the local Ubisensor network, and that the device is emitting ultra-

wideband signals enabling its position to be found.

• Longer (half-second) flashes of the red LED indicate that the tag is searching for signals

from the local Ubisensor network, and that tracking functionality is not available at that

location. Ensure that the tag is within an area of the building covered by the Ubisense In-

Building Location System.

If you are still unsure as to whether or not the Ubitag is operating correctly, contact your system

administrator, who should be able to use Ubisense’s monitoring tools to determine the extent and

cause of any potential problem.
