863.5 MHz, MHz, MHz with reduced power of -4.5 dBm/100 kHz
865.3 MHz, MHz, MHz, MHz with increased output power of 6.2 dBm/100 kHz
868.3 MHz IEEE legacy channel
868.9MHz and MHz using -0.8 dBm/100 kHz output power
channels with RF bandwidth up to 1.4 MHz
864.1 MHz with reduced power of -4.5 dBm/100 kHz
865.8 MHz and MHz with increased output power of 6.2 dBm/100 kHz

8. FHSS Requirements according to [2] March 2009
Listen Before Talk (LBT) has to be applied at each hopping channel.
Carrier power is limited to 25 mWerp [1]

9. Listen Before Talk (LBT)
March 2009
Listen Before Talk (LBT)
Low Duty Cycles can be avoided when applying LBT together with Adaptive Frequency Agility (AFA) [2]
Listening Period:
Fixed part of 5ms
Additional pseudo random part up to 5ms with 0.5 ms resolution if channel is busy at the first try
