Amund The product has to meet the Spectrum Access requirements for the chosen band and transmit power - these are specified in Commission Decision 2013/752/EU and summarised in Annex C.
Some bands allow only a low duty cycle, other allow a maximum duty cycle or "polite spectrum access", and if following the later, the relevant clauses must be met, which are summarised in Annex A.

From Annex B, table B.1: Channel access and occupation rules (e.g. Duty cycle or LBT + AFA) Duty cycle can be 10%, 1% or 0.1%, depending on the channels inside the different Operational Frequency Band Question: Is it possible to increase TX transmission above the allowed duty cycle limit, if the transmission includes LBT (Listen-Before-Talk)? Or are other techniques required?
