BharatNotes What is 5G and Spectrum Allocation?
5G is the fifth generation of cellular technology, designed to deliver peak speeds many times faster than 4G, latency low enough for real-time control, and the capacity to connect a very large number of devices per square kilometre. These services run on radio-frequency spectrum — a finite natural resource owned by the State and licensed to operators. Spectrum allocation is the process by which the Department of Telecommunications (DoT) assigns these airwaves, in India chiefly through transparent competitive auctions conducted on the recommendations of the Telecom Regulatory Authority of India (TRAI).
India's commercial 5G era began on 1 October 2022, when the Prime Minister launched services at the India Mobile Congress, New Delhi.
The 2022 5G Spectrum Auction
The auction ran 26 July–1 August 2022 over 40 rounds and raised gross bids of Rs 1,50,173 crore — the highest in India's history (DoT/PIB, Aug 2022). Spectrum was sold across the 700, 800, 900, 1800, 2100, 3300 MHz and 26 GHz bands.
| Operator | Approx. bid value | Notes |
|---|---|---|
| Reliance Jio | Rs ~88,078 crore | Top bidder; acquired 700 MHz |
| Bharti Airtel | Rs ~43,084 crore | Mid- and high-band focus |
| Vodafone Idea | Rs ~18,784 crore | Selected circles |
| Adani Data Networks | Rs ~212 crore | 26 GHz, captive/private use |
(Figures as per DoT/Ministry of Communications, Aug 2022.)
Bands are grouped as low (700/800 MHz — wide coverage, building penetration), mid (around 3300 MHz — the workhorse balancing speed and reach), and high/mmWave (26 GHz — very high capacity, short range).
How Spectrum Is Allocated
After the 2G case (2012), where the Supreme Court cancelled 122 licences granted on a first-come-first-served basis, auctions became the standard for commercial spectrum to ensure fairness and revenue for the exchequer. The Telecommunications Act, 2023 preserves auctions as the default but permits administrative (non-auction) allocation for specified entries such as satellite/space communication and government/security uses — a model aligned with several ITU member-states for shared, non-exclusive spectrum.
Current Status and Significance
5G has expanded rapidly: services now reach about 99.9% of districts, with operators having deployed over 5 lakh 5G base stations — roughly 5.23 lakh BTS as of 28 February 2026 (DoT data reported to Parliament, late 2025). This supports the Digital India push, enterprise/private networks, IoT, and rural connectivity alongside BharatNet and 4G saturation drives.
Looking ahead, the Bharat 6G Vision (released 22 March 2023) targets India as a leading 6G contributor by 2030, aiming for roughly 10% of global 6G patents, with R&D in terahertz, Open RAN and indigenous chipsets.
UPSC Angle
For Prelims, remember the band categories, the Rs 1,50,173 crore auction figure, the 1 October 2022 launch, and the auction-versus-administrative distinction. For Mains, connect 5G to the digital divide and rural access (GS2/GS3 governance), the 2G judgment on equitable allocation of natural resources, telecom as critical infrastructure and national security, and self-reliance in 6G technology. This is a foundational concept that anchors several questions on the digital economy and emerging technologies rather than a single recurring PYQ.
