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 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.
