Ubisense – Ultra-Wideband Location System – Modular Ubitag V2.0
Introduction
The Modular Ubitag V2.0 is a wireless module intended to be integrated into other devices for the
real-time location of objects within buildings. It transmits ultra-wideband (UWB) 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 UWB 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 Modular Ubitag and important
regulatory information concerning its use and integration into other devices.
Regulatory Information for the United States of America
The Modular Ubitag V2.0 is approved under subpart F (Part 15.517) and Part 15.249 of the FCC
rules as a Modular Transmitter.
The product into which the Modular Ubitag V2.0 is incorporated must bear a label per the FCC
requirements which shows the FCC ID assigned to the Modular Ubitag V2.0 as follows.
Contains FCC ID: SEAMOD21
The following information must be conveyed in the information supplied to the End User of the
product into which the Modular Ubitag V2.0 is incorporated:
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.
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.
The Modular Ubitag V2.0 will only operate (i.e. transmit UWB signals) in conjunction with an
in-building UWB sensor network, which should be professionally installed. The installed
sensor 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.
The user’s manual or instruction manual shall caution the user that changes or modifications to
the equipment not expressly approved by the party responsible for the grant of equipment
authorization issued by the FCC could void the user’s authority to operate the equipment under
the grant of equipment authorization, for example:
CAUTION: Any changes or modifications made to the Modular Ubitag V2.0 which are not
expressly approved by the Ubisense Limited could void the user's authority to operate the
equipment.

Integration information
The dimensions of the module PCB are shown below:
When mounting the tag on another device care must be taken to avoid occlusion of the antennas
by tall components, shielding, or mounting screws. There should be an air gap of at least 1mm
left around both of the antennas to avoid detuning.
While the connector provides some mechanical fixing it is not recommended that this is the only
fixing point. A double-sided pad has been supplied that can be fitted to the top of the screening
can to securely fix the module to a PCB.
When designing the PCB it is recommended that there is no ground plane underneath the
module.
Power should be supplied on the following pins of the header:
2.3V-5.25V DC power input: Pin 3
Ground: Pins 5,6,9,10,14,18,19
A number of pins on the module’s header may be used for digital input/output and analogue input.
Note that application-specific use of these pins will require Ubisense to write modified firmware
for the device, and therefore integrators wishing to make use of these features should contact
Ubisense in the first instance.
The header used on the module is a Major League TSHS-5 10-D-04-A-F-LF, a standard 1.27mm
pitch through-hole pin header. The recommended connector to use with the module is:
Connector: Major League LSSHS-5 10-D-06-F-TB-P-LF (SMD)

Annex A – Additional information pertaining to use of
UWB indoors
This section lists the regulatory requirements for indoor UWB operation in various territories. Note
that this text is presented only for informative purposes, and that all regulatory steps (labeling,
instructions to the user, etc.) listed in the main section of this document must be fulfilled by
integrators supplying the Ubitag Module V2.0 to users.
United States of America
This section reiterates 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. Modular Ubitags operating with
a correctly-installed 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.
Canada
This section reiterates the technical requirements laid down in Industry Canada’s rules which
must be met by UWB devices operating indoors under RSS-210. Modular Ubitags operating with
a correctly-installed Ubisense location system will meet these requirements:
Indoor UWB communications devices, by the nature of their design, shall be capable of
operation only indoors or in locations completely enclosed by walls and a ceiling. The
necessity to operate within a fixed indoor infrastructure (e.g., a transmitter that must be
connected to the AC power lines, an enclosure that is not weatherproof, etc.) may be
considered sufficient to meet this requirement.
EU
This section reiterates the technical requirements laid down in EN302500 which must be met by
UWB devices. Modular Ubitags operating with a correctly-installed Ubisense location system will
meet these requirements:

Ubisense – Ultra-Wideband Location System – Modular Ubitag V2.0
(1) The UWB transmitter equipment conforming to the present document shall not be:
- installed at a fixed outdoor location;
- installed or used in flying models, aircraft and other forms of aviation;
- installed or used in a road or rail vehicle.
(2) To minimize interference to other users of the radio spectrum, in particular outdoor radio
stations, the equipment shall transmit only when it is sending information to a receiver or
attempting to acquire or maintain association. The device shall cease transmission within
ten seconds unless it receives an acknowledgement that its transmission is being
received. An acknowledgement of transmission shall continue to be received by the UWB
device at least every ten seconds, or it shall cease transmitting. Equipment covered by
the present document shall include a receiver mechanism capable of receiving the
reception acknowledgement from an associated receiver.
NOTE: As an example, the receiver mechanism might be capable of operating at
frequency bands given in CEPT/ERC/REC 70-03, annex 1 and tested according to EN
300 220 or EN 300 440.
If a device ceases UWB transmissions due to lack of a reception acknowledgement, it
shall wait for at least twelve seconds before reattempting to send information to a
receiver or to acquire or maintain association with a receiver, unless it first receives an
indication from an external source that its UWB transmissions are likely to be detected. In
this latter case, the device may reattempt to send information to a receiver or to acquire
or maintain association with a receiver immediately.
