5.2 Interpretation of the measurement results
The interpretation of the results for the measurements described in the present document shall be as follows:
• the measured value related to the corresponding limit will be used to decide whether an equipment meets the
requirements of the present document;
• the measurement uncertainty value for the measurement of each parameter shall be recorded;
• the recorded value of the measurement uncertainty shall be, for each measurement, equal to or lower than the
figures in table 5.
For the test methods, according to the present document, the measurement uncertainty figures shall be calculated in
accordance with TR 100 028-1 [1], TS 103 051 [2] and TS 103 052 [3] and shall correspond to an expansion factor
(coverage factor) k = 1,96 or k = 2 (which provide confidence levels of respectively 95 % and 95,45 % in the case
where the distributions characterizing the actual measurement uncertainties are normal (Gaussian)).
Table 7 is based on such expansion factors.

5.3 Test procedures for essential radio test suites
5.3.1 Product Information
The following information shall be stated by the supplier in order to carry out the test suites and/or to declare
compliance to technical requirements (e.g. technical requirements for which no conformance test is included in the
present document):
a) the type of wide band modulation used: FHSS modulation, or any other type of modulation (see clause 4.2.1);
b) where FHSS modulation is used: the number of hopping frequencies, the dwell time per channel and the
maximum time between two instances of use of the same channel (see clause 4.3.1.3). For adaptive FHSS
equipment, the average dwell time;
c) whether or not the system is a non-adaptive system, an adaptive system or a system that can operate in both
an adaptive and non-adaptive mode;
d) for adaptive equipment: whether LBT based DAA or non-LBT based DAA (any other form of DAA) is used
(see clauses 4.3.1.6 and 4.3.2.5) and the maximum Channel Occupancy Time implemented by the equipment.
In case of LBT based adaptive equipment, the CCA time implemented by the equipment. For Load Based
Equipment refered to in clause 4.3.2.5.2.2.2, the value 'q' refered to in point 2 of this clause;
e) for non-adaptive equipment, the maximum duty cycle used by the equipment. For equipment with a dynamic
behaviour with regard to RF Output Power and Duty Cycle, such behaviour shall be described. (e.g. the
different combinations of duty cycle and corresponding power levels shall be declared);
f) for each of the tests to be performed, the worst case operational mode (see clause 5.1.2);
