1Radiocommunication service--
2ApplicationNon-specific SRDsNon-specific SRD using DSSS and other wide band techniques other than FHSS.
For any type of application which fulfils the technical conditions (typical uses are telemetry, telecommand, alarms, data in general and other similar applications).
Devices supporting audio and video applications shall use a digital modulation method with a maximum bandwidth of 300 kHz.
Analogue audio applications are excluded.
Analogue video applications are excluded.
3Frequency band865 - 868 MHz-
5Modulation / Occupied bandwidthDSSS or other wide band modulation / Occupied bandwidth = max. 0.6 MHz.According to current version of EN 300 220-2 V 3.2.1 Table B.1 (Band L) and C.1 (Band X)
