Electromagnetic Compatibility and Radio Spectrum Matters (ERM); Data Communications Using Short Range Devices; Access Protocol, Occupation Rules and Corresponding Technical Characteristics for the Transmission of Data
|Publication Date:||1 October 1999|
The present document covers a radio channel access protocol and provides all the parameters that are essential for its use.
The present document has been designed to be usedwith Short Range Devices sharing a common, single frequency, radio channel and transmitting small (short duration) data packets. Standards EN 300 220-1 , EN 300 330  and I-ETS 300 440  provide technical characteristics for short range device equipment. These products will be co-existing on the same radio spectrum.
The present document specifies the access protocol and the occupation rules for data communications on a radio channel shared by different users. The present document does not specify or impose any restriction on the bit rate, data format or modulation scheme.
This access protocol is not intended for applications requiring continuous (unbroken) data transmission.
