3.1.7 different collocated: Two or more antennas of substantially differing gains or efficiencies, with a
mutual separation distance of 1 m or less, mounted on or within one housing, for the purpose of providing
diversity against multipath fading.
3.1.8 digital modulation: The process by which the characteristics of a carrier wave are varied among a set
of predetermined discrete values in accordance with a digital modulating function.
3.1.9 frame jitter: Time-related, abrupt, spurious variations in the duration of the frame interval.
3.1.10 frame period: A set of consecutive time slots in which the position of each time slot can be
identified by reference to a synchronizing source.
3.1.11 frequency administration commands: Means of control of the EUT directly or through the
companion device. This functionality is provided by the manufacturer to ease testability of the EUT. This
functionality may include providing a control operator with external controls enabled to force the EUT to
use only one or a subset of all the available carriers, and/or one or a subset of all of the available timeslots,
and/or to disable diversity antenna selection. Functionality may be provided by the setting of unique values
within nonvolatile memory in the EUT or companion device, or by other means not at variance with the
requirements of 47CFR15.
3.1.12 identical collocated: Two or more antennas of the same type, with substantially similar
performance and with a mutual separation distance of 1 m or less, mounted on or within one housing, for
the purpose of providing diversity against multipath fading.
3.1.13 initiate: Cause the EUT to attempt to begin user-level communications, typically via the user
interface, or in response to user-level data. For example, for a voice system, to initiate, press the ‘TALK’
control to enable voice communications. See also: activate.
3.1.14 initiating device: A UPCS device that monitors both duplex channels of a duplex transmission pair
in order to qualify both its own and a responding device’s transmit channel for compliance with the spectral
etiquette. See also: responding device. This capability is used in accordance with 47CFR15.323(c)(10) to
simplify the implementation of a UPCS system.
3.1.15 listen before transmit (LBT): An interference avoidance mechanism that mandates monitoring of a
selected channel to determine availability before transmission.
3.1.16 least interfered channel (LIC): An interference avoidance mechanism that extends the LBT
mechanism to monitor all potential channels, determining the LIC, before transmitting on that channel.
Under 47CFR15.323, this mode of operation is limited to those systems with 40 or more channels.
3.1.17 operational failure: The inability of an EUT to perform a function that is required as a response to
system conditions or to a manually or automatically initiated command.
3.1.18 peak transmit power, P
EUT
: The peak power output observed over an interval of time equal to the
transmission burst duration of the EUT under all conditions of modulation.
3.1.19 power spectral density (PSD): The peak pulse power measured in a defined bandwidth.
3.1.20 radiated emission and monitoring tests: Tests performed with RF signal sources (to test
monitoring thresholds) and instrumentation (to measure emissions) connected to test antennas. See:
conducted emission and monitoring tests.
3.1.21 reaction time: The reaction time is the minimum duration of the interference present during the
monitoring interval that must be detected by the EUT so as to determine that the monitored time and
spectrum window is occupied.
