Frequency Availability at 868 MHz
FHSS less encouraging at 868 MHz than at 915 MHz
Use of the entire 7 MHz band limits the channel spacing to less than 100 kHz regardless of FH or non-FH  Maximum data rate constraint
FH does not enable higher transmit power
Duty cycle or LBT also apply for FH systems
Mostly single channel systems in operation today with duty cycle compliance
Availability of multiple channels will be a significant improvement
’Creative’ (slow) hopping or frequency agility
Larger channel spacing to enable higher data rates
