Regions Supporting LBT - Default Settings
Note
The Open Region allows the module to be manually configured within the
full capabilities supported by the hardware. No regulatory limits, including:
frequency range, channel spacing and transmit power limits, are enforced.
The Open Region should be used with caution.
C A U T I O N ! ! !
The EU2 Region does not implement LBT. Therefore, the limits in section
8.10 of the EN 300 220 specification, referring to duty cycle limits, apply.
Since the module does not enforce any duty cycle or power limitations
when configured to use the EU2 region and will transmit 100% of the time
during a tag operation it is the responsibility of the user to appropriately
manage the RF duty cycle and power levels to conform with EN 300 220.
Region LBT Enabled LBT Threshold
EU Yes -96 dBm
EU3 No n/a
Open No -96 dBm
