TRAI Releases Consultation Paper on ‘the Auction of Radio Frequency Spectrum in the Frequency Bands Identified for International Mobile Telecommunications (IMT)’

TRAI Consultation Paper on Spectrum Auction (2025)

Release Date: September 30, 2025
Title: Auction of Radio Frequency Spectrum in the Frequency Bands Identified for International Mobile Telecommunications (IMT)

Background

·         Reference from DoT (15 May 2025): Sought TRAI’s recommendations under Section 11(1)(a) of the TRAI Act, 1997 on auction design for IMT spectrum bands.

·         Earlier Auctions: Based on TRAI’s Sept 2023 recommendations, Government auctioned spectrum in 800, 900, 1800, 2100, 2300, 2500, 3300 MHz & 26 GHz bands in June 2024.

·         Pending Bands:

o    600 MHz – not auctioned earlier due to weak ecosystem and limited global adoption. DoT requests fresh TRAI recommendations.

o    6 GHz (6425–7125 MHz) – only 400 MHz (fragmented: 300 MHz + 100 MHz) immediately available; balance 300 MHz available by 2030. TRAI asked to recommend timing & auction design.

o    1427–1518 MHz (67 MHz) – DoT requests TRAI to suggest a band plan, ensuring a continuous 24 MHz block for government use.

·         Re-farming: 687 MHz of spectrum to be reallocated for IMT services.

Scope of TRAI Recommendations

DoT requests TRAI to provide recommendations on:

1.    Reserve price, band plan, block size, quantum, and conditions for existing bands (800, 900, 1800, 2100, 2300, 2500, 3300 MHz, 26 GHz).

2.    Auction feasibility and timing for 6425–6725 MHz & 7025–7125 MHz bands.

3.    Fresh recommendations for the 600 MHz band.

4.    Band plan for 1427–1518 MHz spectrum, considering government allocation.

5.    Any other regulatory/technical requirements per NFAP/ITU Radio Regulations.

Stakeholder Consultation

·         Written Comments: By 28 October 2025.

·         Counter-Comments: By 11 November 2025.

·         Submission: Preferably by email to advmn@trai.gov.in.

·         Contact for Clarification:

o    Shri Akhilesh Kumar Trivedi

o    Advisor (Networks, Spectrum & Licensing), TRAI

o    Tel: +91-11-20907758

In essence: TRAI seeks stakeholder input on pricing, design, and timing for India’s next major spectrum auctions, including 600 MHz, fragmented 6 GHz, and L-band spectrum, which will shape the roadmap for 5G/IMT-2020 and beyond.

 

[ABS News Service/01.10.2025]

The Telecom Regulatory Authority of India (TRAI) has today released a Consultation Paper on ‘the Auction of Radio Frequency Spectrum in the Frequency Bands Identified for International Mobile Telecommunications (IMT)’.

Department of Telecommunications (DoT) through a letter dated 15.05.2025 sent a reference to TRAI under the terms of clause 11(1)(a) of the TRAI act 1997 for seeking TRAI’s recommendations for the auction of radio frequency spectrum in the frequency bands identified for International Mobile Telecommunications (IMT). Through the reference dated 15.05.2025, DoT informed, inter-alia, as below:

a.    In response to DoT's reference dated 02.08.2023 on auction of RF spectrum in the 600 MHz, 700 MHz, 800 MHz, 900 MHz, 1800 MHz, 2100 MHz, 2300 MHz, 2500 MHz, 3300 MHz, 26 GHz and 37-37.5 GHz, 37.5-40 GHz and 42.5-43.5 GHz bands, TRAI had provided its recommendations on 01.09.2023. Based on the TRAI's recommendations, the Government conducted auction of spectrum in the 800 MHz, 900 MHz, 1800 MHz, 2100 MHz, 2300 MHz, 2500 MHz, 3300 MHz and 26 GHz bands during June 2024.

b.    In the auction held in 2024, the 600 MHz band was not put to auction considering that this band was not sold in the auction held during 2022, the equipment ecosystem has not yet fully developed for this band and only a few countries have deployed 600 MHz in their public network. In the ITU Radio Regulations also, this band has not been identified at the regional or global level for IMT. Therefore, DoT has decided to seek fresh recommendations of TRAI before putting this band for auction.

c.     Out of the total 700 MHz spectrum in the 6425-7125 MHz range, only 400 MHz spectrum in two fragmented chunks at 6425-6725 MHz (300 MHz) and 7025-7125 MHz (100 MHz) are immediately available for auction, and remaining 300 MHz in the 6725-7025 MHz frequency range will be available by December 2030. In view of this, appropriate time for the auction of 6 GHz is required to be explored considering the less developed ecosystem and availability of only 400 MHz spectrum in a fragmented manner.

d.    A total of 687 MHz of spectrum is to be re-farmed for IMT based services.

DoT has also provided LSA-wise quantum of spectrum available with the Government in the existing and new IMT bands, through the reference.

Through the reference dated 15.05.2025, DoT, under the terms of clause 11(1)(a) of the TRAI act 1997, requested TRAI to -

(a)  provide recommendations on applicable reserve price, band plan, block size, quantum of spectrum to be auctioned and associated conditions for auction of spectrum in the existing bands viz. 800 MHz, 900 MHz, 1800 MHz, 2100 MHz, 2300 MHz, 2500 MHz, 3300 MHz, 26 GHz bands.

(b)  explore the possibilities of auction and timing of auction for the newly identified 6425-6725 MHz & 7025-7125 MHz bands. Accordingly, provide recommendations on timing of auction, applicable reserve price, band plan, block size, quantum of spectrum to be auctioned and associated conditions for auction of spectrum in these bands.

(c)  re-examine and provide fresh recommendations for the auction of spectrum in the 600 MHz band.

(d)  provide any other recommendations deemed fit for the purpose of spectrum auction in these frequency bands, including the regulatory/technical requirements as enunciated in the relevant provisions of the latest NFAP/Radio Regulations of the ITU.

TRAI examined the Reference dated 15.05.2025, and through a letter dated 19.06.2025, sought certain additional information/ clarifications from DoT. In response, DoT, through a letter dated 14.08.2025, provided the requisite information/ clarification. Importantly, through the letter dated 14.08.2025, DoT requested TRAI to recommend a possible band plan for the 67 MHz spectrum between 1427-1518 MHz considering the need to assign a continuous 24 MHz block to the Government user.

In this regard, a consultation paper on ‘Auction of Radio Frequency Spectrum in the Frequency Bands Identified for International Mobile Telecommunications (IMT)’ has been placed on the TRAI’s website (www.trai.gov.in) for seeking comments and counter-comments from stakeholders. Written comments on the issues raised in the consultation paper are invited from stakeholders by 28th October 2025 and counter-comments by 11th November 2025.

The comments/ counter-comments may be sent, preferably in electronic form at advmn@trai.gov.in. For any clarification/ information, Shri Akhilesh Kumar Trivedi, Advisor (Networks, Spectrum & Licensing), TRAI may be contacted at telephone number +91-11-20907758.
