NOTIFICATION
New Delhi, the 25 November, 2025
G.S.R. 866(E).— The following draft rules, which the Central Government proposes to make in
exercise of the powers conferred by sub-section (6) of section 4 read with clause (h), to sub-section (2) of
section 56 of the TelecommunicationsAct, 2023 (44 of 2023), are hereby published for the information of
all persons likely to be affected thereby and notice is hereby given that the said draft rules shall be taken
into consideration after the expiry of a period of thirty days from the date on which copies of this
notification as published in the Official Gazette, are madeavailable to the public;
Objections or suggestions, if any, may be addressed to the Joint Secretary (Telecom), Department
of Telecommunications, Ministry of Communications, Government of India, Sanchar Bhawan, 20, Ashoka
Road, New Delhi- 110001;
The objection or suggestion which may be received from any person with respect to the said draft
rules before the expiry of the aforesaid period shall be taken into consideration by the Central Government.
1. Short title, commencement and application. — (1) These rules may be called the Use of Short-
Range Automotive Radar System in the 77 to 81 GHz band (Exemption from Assignment Requirement)
Rules, 2025.
(2) They shall come into force on the date of their publication in the Official Gazette.
2. Application. — These rules shall apply in the 77 to 81 GHz band.
3. Definitions. — (1) In these rules, unless the context otherwise requires, -
(a) "Act" means the Telecommunications Act, 2023 (44 of 2023);
(b) "Authority" means the authority notified by the Central Government.
(c) “equivalent isotropic radiated power” or “e.i.r.p” means the total power that would have to be
radiated by a hypothetical isotropic antenna to give the same signal strength as the actual source in
the direction of the antenna's strongest beam;
(d) "power spectral density" means the total energy output per unit bandwidth from a pulse or
sequence of pulses for which the transmit power is at its maximum level, divided by the total
duration of the pulses and the total time does not include the time between pulses during which the
transmit power is off or below its maximum level;
(e) "device" means the radiators operating in the frequency bands 77-81 GHz that use wideband
digital modulation techniques and provide a wide array of high datarate in mobile and fixed
communications for individuals, businesses, and institutions;
(f) "Vehicles" include, but are not limited to, passenger cars, busses, trucks, aircraft while taxing,
railroad train locomotives, train cars, monorails or trams, construction vehicles, motorcycles,
scooters, and boats and ships operated within territorial waters of India.
(2) The words and expressions used in these rules and not defined, but defined in the Act
shall have the same meaning respectively assigned to them in the Act.
4. Exemption. — No frequency assignment shall be required by any person to establish, maintain,
work, possess or deal in any wireless equipment for the purpose of short-range automotive radar system in
the 77 to 81 GHz frequency band on non-interference, non-protection and shared (non-exclusive) basis, and
using the technical parameters as specified in the Table below, namely:—
TABLE
Technical characteristics
+---------------------+---------------+---------------+---------------------+-----------------------------+
| Device Type | #Max. | *Max. Peak | Max. Emission | Maximum |
| | Average EIRP | e.i.r.p | Bandwidth | unwanted |
| | | | | emissions Limit |
+---------------------+---------------+---------------+---------------------+-----------------------------+
| Short Range | 50 dBm | 55 dBm | 4 GHz | -32 dBm/MHz |
| Automotive Radar | | | | |
+---------------------+---------------+---------------+---------------------+-----------------------------+
# To be measured over 1 MHz resolution bandwidth using average detector and integrated over the total
emission bandwidth
* To be measured over 1 MHz resolution bandwidth using peak detector over the entire emission
bandwidth, shall not be integrated over the emission bandwidth.
4.1 Operational Restrictions.— (1) This use will be limited to vehicles only.
5. Interference.— (1) The effect of unwanted energy due to one or a combination of emissions,
radiations or induction upon reception in a radio equipment, manifested by any performance degradation,
misinterpretation, or loss of information which could be extracted in the absence of such unwanted energy,
where any person operating as per the Telecommunications Act, 2023 (44 of 2023) or license under the
Indian Telegraph Act, 1885 (13 of 1885) which is valid pursuant to sub-section (6) of section 3 of the Act
informs the Authority that his licensed system is getting harmful interference from any other radio
equipment exempted under these rules, then such Authority shall call upon the user of such unauthorised
wireless equipment to take necessary steps to avoid interference by relocating the equipment, reducing the
power and using special type of antennae, failing which such Authority shall recommend discontinuation of
such wireless use.
(2) The Authority shall give a reasonable opportunity to the user of wireless equipment before making
recommendation of discontinuation of wireless use under sub-rule (1).
6. Equipment. - (1) The wireless equipment shall be type approved and designed and constructed in
such a manner that the bandwidth of emission and other parameters shall conform to the limits specified in
rule 4 and 5. The application for obtaining equipment type approval shall be made to the Central
Government in the format given in Annexure.
(2) The safety related requirements shall be as per the International or National standards such as
ITU/ETSI/ANSI/BIS/TEC/ICNIRP for the respective devices and frequency bands.
