4.3.1.11.2 Limits
Adaptive Frequency Hopping equipment shall comply with the requirements defined in clauses 4.3.1.6.1 (LBT based
DAA) or 4.3.1.6.2 (non-LBT based DAA) in the presence of a blocking signal with characteristics as provided in
table 3.

NOTE 1: The highest blocking frequency shall be used for testing the lowest operating hopping
frequency, while the lowest blocking frequency shall be used for testing the highest hopping
frequency.
NOTE 2: A typical value which can be used in most cases is -50 dBm/MHz.
4.3.1.11.3 Conformance
The conformance tests for this requirement are part of the conformance tests defined for adaptivity in clause 5.3.7 and
more specifically clause 5.3.7.2.1.1.
4.3.2 Technical requirements for other types of Wide Band modulation
Equipment using wide band modulations other than FHSS is equipment that typically operates on a fixed frequency (see
note). This equipment shall comply with the requirements in clauses 4.3.2.1 to 4.3.2.10.
NOTE: The equipment is allowed to change its normal operating frequency when interference is detected, or to
prevent causing interference into other equipment or for frequency planning purposes.
For equipment using FHSS modulation, the requirements in clause 4.3.1 shall apply.
4.3.2.1 RF output power
This requirement applies to all types of equipment using wide band modulations other than FHSS.
4.3.2.1.1 Definition
The RF output power is defined as the mean equivalent isotropic radiated power (e.i.r.p.) of the equipment during a
transmission burst.
4.3.2.1.2 Limit
For adaptive equipment using wide band modulations other than FHSS, the maximum RF output power shall be
20 dBm.
The maximum RF output power for non-adaptive equipment shall be declared by the supplier and shall not exceed
20 dBm. See clause 5.3.1 m). For non-adaptive equipment using wide band modulations other than FHSS, the
maximum RF output power shall be equal to or less than the value declared by the supplier.
This limit shall apply for any combination of power level and intended antenna assembly.
4.3.2.1.3 Conformance
The conformance tests for this requirement are (part of the procedure) defined in clause 5.3.2.
4.3.2.2 Power Spectral Density
This requirement applies to all types of equipment using wide band modulations other than FHSS.
