scope:

The present document applies to Short Range Devices (SRDs) in Road Transport and Traffic Telematics (RTTT) systems as described in the scope of EN 302 858-1 [1]: - with an integral antenna; - for low power motion and distance monitoring radars for mobile applications only; - operating in the 24,05 GHz to 24,25 GHz frequency range. The applicability of the present document covers only the 24 GHz Narrow Band Short Range Radar (NBSRR) for road vehicles. The present document does not necessarily include all the characteristics which may be required by a user, nor does it necessarily represent the optimum performance achievable. The present document is intended to cover the provisions of Directive 1999/5/EC [i.2] (R&TTE Directive), article 3.2, which states that "... radio equipment shall be so constructed that it effectively uses the spectrum allocated to terrestrial/space radio communications and orbital resources so as to avoid harmful interference".
