Introduction

The allocation and judicious use of the 6GHz spectrum band are poised to revolutionize India’s digital landscape, transforming Wi-Fi capabilities and accelerating mobile internet via 5G and future 6G technologies. This comprehensive overview explains the technical aspects, government policies, and industry debates around the 6GHz band, highlighting its potential impact on connectivity and the digital economy.

What is the 6GHz Spectrum?

The 6GHz frequency range (roughly 5925 MHz to 7125 MHz) is part of the radio spectrum that enables high-speed wireless communication. In the context of India, it is divided broadly into two segments:

• Lower 6GHz (5925-6425 MHz): Dedicated for unlicensed use, primarily enhancing Wi-Fi services under regulated power limits.
• Upper 6GHz (6425-7125 MHz): Reserved for licensed mobile network use to support expanding 5G and upcoming 6G networks.

The availability of additional bandwidth in this spectrum allows for faster data rates and reduced congestion on wireless networks compared to traditional Wi-Fi frequency bands (2.4 GHz and 5 GHz).

Role of 6GHz in Wi-Fi and Mobile Networks

6GHz significantly enhances Wi-Fi when used with Wi-Fi 6E and Wi-Fi 7 standards by offering wider channels, lower latency, and less interference. This results in faster connectivity and greater capacity for devices.

For mobile networks, especially 5G and 6G, the 6GHz spectrum provides more bandwidth for data transmission and supports improved coverage in urban and suburban areas. It is vital for future-proofing telecom infrastructure to handle increasing data demands and Internet of Things (IoT) applications.

India’s 6GHz Spectrum Policy and Auction

India’s government initiated policy to delicence 500 MHz of the lower 6GHz band for unlicensed use to promote Wi-Fi and similar technologies. Concurrently, 400 MHz of spectrum will be auctioned for licensed mobile services, with an additional 300 MHz planned by 2030. This hybrid approach balances accessibility for consumers with the strategic growth of cellular networks.

Leading telecom operators Reliance Jio and Vodafone Idea advocate for auctioning the entire 6GHz band for mobile services to broaden 5G/6G reach. However, major global tech companies like Apple, Amazon, and Cisco recommend reserving more spectrum exclusively for Wi-Fi to ensure ecosystem readiness and compatibility.

Telecom Regulatory Authority of India (TRAI) continues stakeholder consultations to finalize timelines and terms, aiming to align with global standards post the World Radiocommunication Conference (WRC-27).

Benefits of 6GHz Spectrum for India

• Enhanced Wi-Fi performance: Wider channels and reduced interference improve indoor connectivity for homes, offices, and public spaces.
• Accelerated 5G/6G rollouts: Provides essential bandwidth for mobile operators to expand high-speed coverage and futuristic IoT services.
• Bridging digital divide: Supports government initiatives like PM-WANI (public Wi-Fi) and BharatNet (rural broadband) ensuring inclusive digital access.
• Economic growth and innovation: Enables new applications in automation, telemedicine, education, and smart cities.
• Global alignment: India adheres to international norms, facilitating ecosystem compatibility and technology adoption.

Challenges and Controversies

• Industry splits: Telcos push for licensed auctioning vs. tech firms backing unlicensed Wi-Fi use.
• Device and ecosystem readiness: Concerns over availability of consumer devices and infrastructure for upper 6GHz band mobile deployment.
• Spectrum management: Need for balancing licensed and unlicensed use to avoid interference and maximize utility.
• Revenue implications: Licensed auctions generate government revenue but potentially restrict Wi-Fi access; unlicensed access supports innovation but limits auction income.

Future Outlook for 6GHz Spectrum

The 6GHz band is strategic for India’s digital future, shaping the quality of mobile and wireless broadband. Regulatory decisions post-WRC-27 will clarify auctioning schedules and delicensing extents. Innovations in technology and multistakeholder cooperation will determine the pace and scope of benefits reaching citizens and industries.

FAQs

What frequencies does the 6GHz spectrum cover in India?

India’s 6GHz band spans from 5925 MHz to 7125 MHz, split between lower 6GHz for unlicensed use (Wi-Fi) and upper 6GHz for licensed mobile networks like 5G/6G.

How will 6GHz improve Wi-Fi connectivity in India?

The 6GHz spectrum allows wider channels, less interference, and higher data speeds via Wi-Fi 6E and 7, enabling faster and more reliable wireless internet in homes and public areas.

Why is there a debate over 6GHz spectrum allocation in India?

Telecom operators prefer full licensed allocation for 5G services, while global tech firms advocate reserving significant bands for unlicensed Wi-Fi to ensure device ecosystem and interoperability readiness.

What are the expected benefits of 6GHz for mobile networks?

6GHz offers expanded bandwidth to support faster, more reliable 5G and 6G connectivity, improving coverage and enabling emerging technologies like IoT, smart cities, and automation.

When will the 6GHz spectrum auction take place?

Initial auctions for 400 MHz in the 6GHz band are scheduled soon, with an additional 300 MHz planned by 2030. Final decisions await international standards alignment post WRC-27.
