doc.: IEEE 802.15-<doc#> <month year> doc.: IEEE 802.15-<doc#> July 2009 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 Khanh Tuan Le (TI) <author>, <company>
