Introduction
The Ubitag V2.2 is a wireless device intended to be used for the real-time location of objects
within buildings. It transmits ultra-wideband pulses which are picked up by a network of
basestations (Ubisensors) placed inside the building, allowing the 3D position of the tag to be
found. The use of ultra-wideband technology enables greater positioning accuracy within
buildings than other wireless technologies, because it is much less susceptible to multipath
interference effects. Applications of the system include healthcare, workplace productivity,
security, retail management and manufacturing.
This document describes the features and specifications of the Ubitag, important regulatory
information concerning its use, and details on how to diagnose potential problems.
Information to the User
The Ubitag V2.2 is an ultra-wideband (UWB) wireless device certified under FCC Part 15.517. Its
use is subject to technical requirements for indoor UWB systems, in particular the stipulation that
the devices must only be used indoors. Users should note carefully the following information:
•
•
•
CAUTION: This equipment may only be operated indoors. Operation outdoors is in
violation of 47 U.S.C. 301 and could subject the operator to serious penalties.
Ubitags will only operate (i.e. transmit UWB signals) in conjunction with an in-building
Ubisensor network, which should be professionally installed. The installed Ubisensor
network will be configured to cover only the area inside the building, preventing Ubitags
from emitting UWB signals outdoors. Contact your system administrator if you are unsure
as to the extent of the coverage of the Ubisense In-Building Location System in your
building.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) this device may not cause harmful interference, and (2) this device
must accept any interference received, including interference that may cause undesired
operation.
Users should also carefully note the following information:
•
•
CAUTION: Any changes or modifications made to the Ubitag which are not expressly
approved by the Ubisense Limited could void the user's authority to operate the
equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following
measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
-- Consult the dealer or an experienced radio/TV technician for help.

Installation and Operation Instructions
Switching the Ubitag on for the first time
The Ubitag is supplied with a battery, which needs to be fitted prior to operating the tag.
Fitting or replacing the batteries in the Ubitag
The Ubitag uses a Panasonic CR2477 3V lithium coin cell (or equivalent). Ubitags frequently
report their battery health to the system via the Ubisensors, so system administrators should be
notified by the system when the battery in a particular tag requires replacement.
To replace the battery in a Ubitag:
1.
2.
3.
4.
Unscrew the four screws in the back of the enclosure
Remove the rear of the enclosure to allow access to the battery
Slide out the old battery and dispose of carefully
Replace the battery with a new one, being careful to observe correct polarity
When the battery has been replaced, the Ubitag will flash its LED to indicate correct start-up, and
the Ubisense Location System will then be able to determine the Ubitags’ location.
Replace the PCB back into the front of the enclosure, replace the rear enclosure half and then
tighten the four screws removed previously to complete reassembly of the device.
Should the Ubitag not flash its’ LED to indicate correct start-up after the battery has been
replaced, remove the battery, check that it is fresh, wait for 30 seconds, and reinsert the battery.
Contact your system administrator if you continue to have problems replacing the battery in the
Ubitag.

Troubleshooting
The activity of the LEDs on the Ubitag may be used to diagnose potential problems with the
device:
•
•
Periodic, short (less than 1/10th second) flashes of the LED indicate that the tag is in
communication with the local Ubisensor network, and that the device is emitting UWB
signals enabling its position to be found.
Longer (half-second) flashes of the 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 covered by the Ubisense 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.

Requirements for device operation
This section lists the technical requirements laid down in the FCC’s rules which must be met by
UWB devices operating indoors under §15.517 of those rules. Ubitags operating with a correctlyinstalled Ubisense location system will meet these requirements.
(1) Indoor UWB devices, by the nature of their design, must be capable of operation only
indoors. The necessity to operate with a fixed indoor infrastructure, e.g., a transmitter that
must be connected to AC power lines, may be considered sufficient to demonstrate this.
(2) The emissions from equipment operated under this section shall not be intentionally
directed outside of the building in which the equipment is located, such as through a
window or a doorway, to perform an outside function, such as the detection of persons
about to enter a building.
(3) The use of outdoor mounted antennas, e.g., antennas mounted on the outside of a
building or on a telephone pole, or any other outdoors infrastructure is prohibited.
(4) Field disturbance sensors installed inside of metal or underground storage tanks are
considered to operate indoors provided the emissions are directed towards the ground.
(5) A communications system shall transmit only when the intentional radiator is sending
information to an associated receiver.
