In order to comply with the output power limitations in Europe, the maximum values given in
Table 8 below must be observed. Modulations M14, ML2 and ML3 are considered to be
wideband modulations and therefore subject to the power spectral density requirements. Lower
power levels for these configurations ensure compliance to the specifications. The limits are
given based on the maximum allowed power level in a specific band and temperature
conditions.

2.5.2.1. Spectrum Access and Mitigation Requirements
As part of the requirements for compliance, the applications must observe the restrictions that
are listed in Table 5. Specifically, the spectrum access and mitigation requirements (e.g. Duty
Cycle or LBT+AFA) have to be met. Some sub-bands (see Table 5) allow limited Duty cycling
while some others let the user choose between limited Duty cycling and LBT+AFA
implementation. In case of LBT+AFA, AFA (Adaptive Frequency Agility) has to be implemented
in the customer’s SW stack since there is no specific hardware support for this functionality.
2.5.2.1.1.
Duty Cycling
Table 5 lists all sub-bands together with the usage requirements. In this table, Duty Cycling
requirements are listed under “
Restrictions
” column. It applies to all transmitters excluding
those with a LBT facility with AFA (explained in the next sub-section). The Duty Cycle is defined
as the ratio, expressed as a percentage, of the maximum transmitter “ON” time monitored over
one hour, relative to a one hour period. The device may be triggered either automatically or
manually. And, depending on how the device is triggered, the duty cycle is either fixed or
random.
For automatic operated devices, either software controlled or pre-programmed devices, the
OEM integrator or end product developer shall declare the duty cycle class or classes in the
end-product user manual or user guide. For manual operated or event-dependent devices, with
or without software controlled functions, the integrator shall declare whether the device once
triggered, follows a pre-programmed cycle, or whether the transmitter remains on until the
trigger is released or the device is manually reset. The integrator shall also give a description of
the application for the device and include a typical usage pattern. The typical usage pattern as
declared by the integrator shall be used to determine the duty cycle and hence the duty class.
