1 Scope
The present document specifies the technical requirements and methods of measurement for Short Range Devices
(SRD) working as broadband devices with at least 500 MHz bandwidth in the 22,000 GHz to 26,65 GHz frequency
range intended for Road Transport and Traffic Telematics (RTTT) applications, such as automotive 24 GHz
Short Range Radar (SRR) for e.g. obstacle detection, stop and go, blind spot detection, parking aid, backup aid,
precrash and other automotive applications.
The present document covers transmitters intended to operate in a temporary frequency designation under the 24 GHz
ECC decision CEPT/ECC/DEC/(04)10 [i.7], the EU Commission decision on 24 GHz SRR 2005/50/EC [i.1] and the
amendment as presented in RSCOM11-07 [i.8].
The operating frequency range for intentional UWB emissions shall be from 22,000 GHz to 26,65 GHz until
30th June 2013 and from 24,25 GHz to 26,65 GHz until 1st January 2022.
The present document applies to:
a) Transmitters in the range from 22,000 GHz to 26,65 GHz operating as broadband devices over the specific
bandwidth defined for the individual devices.
b) Receivers operating in the range from 22,000 GHz to 26,65 GHz.
c) Integrated transceivers.
The present document contains the technical characteristics and test methods for short range radar equipment fitted with
integral antennas.
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 covers short range radar mobile applications. The present document covers only SRR equipment
for road vehicles.
The present document complies with field limits for human exposure to electromagnetic fields as provided by the
EC Recommendation 1999/519/EC [i.2] and the methods for compliance demonstration in EN 50371 [i.3].
