2ApplicationNon-specific SRDsNon-specific SRD using FHSS modulation.
For any type of application which fulfils the technical conditions (typical uses are telemetry, telecommand, alarms, data in general and other similar applications).
3Frequency band865.000 - 868.000 MHz-
4Channelling-The preferred channel spacing is 100 kHz allowing for subdivision into 50 kHz or 25 kHz.
5Modulation / Occupied bandwidthFHSS / Bandwidth per channel: equal or less than 50 kHz.According to current version of EN 300 220-2 V 3.2.1 clause 4.3.10.

8Channel access and occupation rulesDuty cycle max. 1 % or LBT and according to comments and EN 300 220-2.
Techniques to access spectrum and mitigate interference that provide at least equivalent performance to the techniques described in harmonised standards adopted under Directive 2014/53/EU must be used.
Number of hopping channels: equal or greater than 58.
Bandwidth per channel: equal or less than 50 kHz.
Duty cycle max. 1 % (The duty cycle applies to the entire transmission (not at each hopping channel)) or LBT.
