Monitoring test procedure—general
The threshold used for channel access deferral is based on the power and emission bandwidth
measurements of 6.1.2 and 6.1.3.
Each test will generally consist of the following steps:
a) Using either carrier and/or access channel administration commands or out-of-operating-region
interference (see 7.2.3), restrict operation of the EUT to a target channel or set of channels on
which the test will be performed. Initiate transmission without the presence of interference on
the target region to verify that the EUT is operating. The communication is then stopped.
b) Introduce interference on the target channel or channels at the prescribed level and time duration
as appropriate to the EUT and verify that the EUT defers use of that channel or channels when
initiation of a connection is attempted.
c) The EUT passes when it operates only in the allowed combinations of operating environments.
Standard test frequencies
Monitoring tests shall be performed on the carrier closest to the center of the band, except when two or all
carriers are specified. When two carriers are specified, the carriers adjacent to the carrier closest to the
center of the band may be used.
Timeslot and carrier equivalence
The monitoring procedure tests of Clause 7 that specify interference applied on various carriers may be
implemented on a single carrier using interference synchronized with the timeslot structure, with the
interference level adjusted by timeslot equivalently to the adjustments specified for interference present on
individual carriers.
Calibration of levels
Calculation of thresholds
15
Calculate the upper threshold limit T
U
according to the provisions of 4.3.3, and the lower threshold limit T
L
according to the provisions of 4.3.4.
Calibration of test interference field strength (radiated technique)
Refer to Clause 4 and Annex B.
Procedures for using out-of-operating-region interference
The multicarrier generator in C.1 is an interference source that can generate independently controlled (on or
off) CW signals on the center frequencies of all EUT carriers. This generator can be used to apply out-of-
operating-region interference to target specific frequency ranges or time intervals for threshold testing by
blocking the other frequencies and/or timeslots, unless the frequency selectivity of the EUT is extremely
poor. The procedures given here are intended to ensure that residual power from the generator falling on
the target (unblocked) frequency does not corrupt the test.
