Ubisense – Ultra-wideband In-Building Location System – Ubisensor V1.0
8. Finally, when all sensor cells have been tuned, select the option “(no cell selected)” from
the drop-down menu. This will re-enable the radio output of all master Ubisensors (and
will set their output powers at the tuned values), and will re-enable transmission of UWB
signals from Ubitags.
By following these instructions, all sensor cells in the system will have been tuned so that their
radio signals cannot be picked up by Ubitags outside the building, and so Ubitags will only
transmit ultra-wideband signals indoors, in accordance with FCC Part 15.517.
Troubleshooting
If you believe that a Ubisensor is not functioning correctly, and the Ubisense location system
management tools are not able to diagnose the problem, it is likely that the Ubisensor is not
communicating with the rest of the location system for some reason. Check the following:
• The Ubisensor is connected to a power supply, and the supply is switched on.
• The networking cable is fully plugged in at both ends.
• Your local network port is connected to the rest of your network.
• The link light corresponding to the Ubisensor network connection is illuminated on the
nearest upstream switch.
If you are still unable to determine the cause of the problem, contact your system installer or
Ubisense.
