Amund
That's a term often used for this type of operation, but it has to meet the
requirements referenced in clause 4.5

Thanks Charlie
Would you accept "Listen-before-talk" as "polite spectrum access"?
Best regards Amund

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.
Best regards
Charlie

Subject: [PSES] EN 300 220 - TX duty cycle for SDR
The Duty Cycle at the operating frequency shall not be greater than values in
annex B or any NRI for the chosen operational frequency band(s).
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?
Best regards Amund
