1 Scope
The present document applies to the following equipment types:
• automotive radar equipment operating in the 24,05 GHz to 24,25 GHz frequency range (narrowband radar
equipment);
• automotive radar equipment operating in the 24,05 GHz to 24,50 GHz frequency range (WLAM wideband low
activity mode radar equipment). The WLAM mode can be activated and operated in three different sub-modes
(SM) as defined in CEPT/ECC Report 164 [i.8]:
- SM1: Forward facing Radars, Front-permanent Calibration sub-mode.
- SM2: Forward facing Radars, Front Emergency APPS sub-mode, activated for emergency braking
support in case of a crash event monitored by a camera, for a vehicle speed above 20 km/h.
- SM3: Rear facing Radars, Rear-parking sub-mode, activated only when the vehicle moves back to better
discriminate pedestrians, v < 30 km/h.
A radar EUT can work in one, two, or three of these sub-modes. The radar sensor manufacturer has to
declare in which sub-modes the EUT operates and how to switch between the sub-modes.
The present document contains the technical characteristics and test methods for narrowband radar equipment fitted
with integral antennas operating in the frequency range from 24,05 GHz to 24,25 GHz or from 24,05 GHz to 24,50 GHz
and references CEPT/ERC Recommendation 70-03 [i.1] and EC Decision 2013/752/EU [i.2].
Table 1 shows the frequency bands as designated to narrowband radar and WLAM radar devices.

6 Draft ETSI EN 302 858 V2.1.0 (2016-04)
1 Scope
The present document applies to the following equipment types:
• automotive radar equipment operating in the 24,05 GHz to 24,25 GHz frequency range (narrowband radar
equipment);
• automotive radar equipment operating in the 24,05 GHz to 24,50 GHz frequency range (WLAM wideband low
activity mode radar equipment). The WLAM mode can be activated and operated in three different sub-modes
(SM) as defined in CEPT/ECC Report 164 [i.8]:
- SM1: Forward facing Radars, Front-permanent Calibration sub-mode.
- SM2: Forward facing Radars, Front Emergency APPS sub-mode, activated for emergency braking
support in case of a crash event monitored by a camera, for a vehicle speed above 20 km/h.
- SM3: Rear facing Radars, Rear-parking sub-mode, activated only when the vehicle moves back to better
discriminate pedestrians, v < 30 km/h.
A radar EUT can work in one, two, or three of these sub-modes. The radar sensor supplier has to declare
in which sub-modes the EUT operates and how to switch between the sub-modes.
The present document contains the technical characteristics and test methods for narrowband radar equipment fitted
with integral antennas and applies to transmitters and receivers with integral antennas and references CEPT/ERC
Recommendation 70-03 [i.1] and EC Decision 2013/752/EU [i.2].
Table 1 shows the frequency bands as designated to narrowband radar and WLAM radar devices.
Table 1: Narrowband and WLAM radar devices frequency of operation
Frequency bands / frequencies
Transmit 1 24,05 GHz to 24,25 GHz
Receive 1 24,05 GHz to 24,25 GHz
Transmit 2 24,05 GHz to 24,50 GHz (see note)
Receive 2 24,05 GHz to 24,50 GHz (see note)
NOTE: For WLAM operation mode only.
The present document contains requirements to demonstrate that radio equipment both effectively uses and
supports the efficient use of radio spectrum in order to avoid harmful interference.
In case of differences (for instance concerning special conditions, definitions, abbreviations) between the present
document and ETSI EN 303 396 [1], the provisions of the present document take precedence.

requirement on maximum dwell time.
For the fast modulation condition, the expression "accumulated" means that within the same 40 kHz range the sum of
individual dwell times in a 3 ms interval has to be smaller than 4 µs.
For the slow modulation condition, access to a 40 kHz range is allowed during max.1 ms with a minimum repetition
time of 40 ms. During the 1 ms duration, the 40 kHz range may be left and re-entered. Outside of the 1 ms period,
access at any other time to the same 40 kHz range is only allowed with less than -10 dBm e.i.r.p. or with fulfilling the
fast modulation condition.
