While public attention usually stays fixed on mobile plan price hikes and corporate IPO timelines, a massive behind-the-scenes structural clash has broken out at the Department of Telecommunications (DoT). This regulatory standoff is centered on the high-frequency 26 GHz millimeter-wave (mmWave) band—a dense slice of airwaves bought by telecom operators for thousands of crores during the landmark 2022 spectrum auctions.
Reliance Jio has shaken up the industry by filing an official engineering request to repurpose its licensed 26 GHz holdings. Instead of routing these airwaves purely through traditional mobile networks, Jio wants to deploy low-cost, ultra-high-capacity wireless broadband directly to consumer homes using standard IEEE Wi-Fi protocols (such as Wi-Fi 7 and WiGig).
Bharti Airtel immediately recognized the massive competitive threat and lodged a formal technical protest. Airtel argues that shifting away from traditional global cellular frameworks risks causing localized network interference and upending the economic fairness of the licensed market.
In this comprehensive policy breakdown, we analyze the core technology architectures driving this dispute, look at the arguments presented by both telecom giants, and evaluate how the government’s pending decision will shape the future of high-speed internet in India.
High-Level Breakdown of the 26 GHz Spectrum Matrix
| Battlefront Column | Reliance Jio’s Technological Vision | Bharti Airtel’s Regulatory Counter |
| Preferred Protocol | IEEE 802.11 Framework (Open-source Wi-Fi 7 / WiGig standard) | 3GPP Mobile Framework (Conventional 5G cellular / Standalone FWA) |
| Core Equipment Model | Mature, globally mass-produced, low-cost customer-premise devices | Proprietary, high-cost base stations controlled by legacy tech vendors |
| Primary Economic Aim | Lower infrastructure deployment costs to rapidly scale home broadband | Shield multi-billion-dollar investments and preserve licensed asset value |
| Technical Challenges | Finding the right balance for high outdoor power transmission limits | Preventing signal leak issues from bleeding into adjacent 5G sectors |
| Government Standard Status | Draft guidelines under review by TEC and TSDSI | Demanding strict adherence to established international cellular limits |
The Core Problem: The Millimeter-Wave Dilemma
To understand why this corporate battle is happening, it helps to look at the physical limitations of the 26 GHz band itself. When operators bought these airwaves in 2022, mmWave technology was praised for its ability to deliver fiber-like speeds, ultra-low latency, and massive bandwidth over the air.
However, real-world deployments have faced steep economic challenges globally. Frequencies in the 26 GHz range have incredibly poor propagation characteristics—meaning the signals cannot travel long distances and struggle to penetrate common obstacles like concrete walls, glass, or trees.
To provide reliable outdoor mobile 5G coverage using this band, operators would have to install millions of dense, expensive antenna nodes every few hundred meters. Because consumer mobile devices natively supporting mmWave are still rare in India, these expensive airwaves have sat largely underutilized.
Jio’s Play: Leveraging the Mature Wi-Fi Ecosystem
Jio’s engineering proposal offers a clever workaround to this economic hurdle. By shifting its 26 GHz spectrum allocation over to open-source IEEE Wi-Fi standards, Jio can tap into a highly mature, mass-produced hardware market.
Building customer equipment (CPE) for 3GPP-compliant Fixed Wireless Access (FWA) routers requires using proprietary technology controlled by a handful of global manufacturers, pushing consumer hardware costs up toward the $200 mark. In contrast, standard Wi-Fi chips are highly affordable. Deforming the 26 GHz band to run high-capacity outdoor wireless links directly into homes bypasses these steep hardware costs, allowing Jio to deploy high-speed broadband at a fraction of the price.
Airtel’s Counter: Defending the 3GPP Moat and Interference Rules
Airtel’s formal objection with the DoT is built on clear technical and regulatory rules. The operator argues that spectrum purchased under mobile broadband guidelines must strictly adhere to 3GPP specifications. Shifting a major operator over to an entirely different protocol family creates three major problems:
- Localized Signal Interference: Because Jio and Airtel hold adjacent slices of the 26 GHz band, Airtel warns that high-power outdoor Wi-Fi transmitters could cause severe co-channel interference, degrading the performance of nearby 5G cellular sectors.
- Unverified Radiation Frameworks: India’s strict electromagnetic field (EMF) safety rules are calibrated explicitly around 3GPP designs. Airtel argues that the power levels required for outdoor Wi-Fi deployments (ranging between 20W and 63W) need deep technical validation before moving to commercial lines.
- Protecting Investment Fairness: Airtel has spent thousands of crores building out its premium 5G network under the assumption that everyone would follow the same cellular rules. Allowing a competitor to pivot to a lower-cost, unlicensed-style model changes the competitive landscape mid-game.
Step-by-Step: How Regulators are Evaluating the 26 GHz Clash
Because this technical dispute could redefine the telecom sector, the government’s technical arms are running a highly structured validation process.
1.DoT Referral to Technical Bodies:
Following Jio’s initial proposal, the DoT officially tasked the Telecommunication Engineering Centre (TEC) and the Telecommunications Standards Development Society, India (TSDSI), to draft a localized national standard.
2.Calibrating Safe Power Thresholds:
Technical committees are analyzing specific transmission limits, evaluating how high-power outdoor Wi-Fi configurations operating around 43 dBm (20W) and 48 dBm (63W) impact environmental safety.
3.Designing Protective Guard Bands:
To completely eliminate signal bleeding between competing operators, the TEC is modeling a physical 200 MHz guard band—leaving a slice of spectrum deliberately empty to act as a buffer zone.
4.Publishing the Final Policy Framework:
Once stakeholder consultations wrap up, the DoT will release its final policy order, establishing whether operators can use alternative technology standards or if the band will stay exclusive to 3GPP.
Long-Term Market Risks and Strategic Outcomes
- A Landmark Precedent for Technology Neutrality: If the DoT rules in Jio’s favor, it permanently establishes that India’s spectrum framework is genuinely technology-neutral, allowing licensed telcos to run any globally recognized standard on their airwaves.
- Impact on Future 6G Evolution Plans: Because the mmWave band is seen as a key stepping stone toward upcoming 6G network layers, fracturing the spectrum across clashing protocol standards today could complicate long-term infrastructure planning.
- Shifting the Home Broadband Cost Structure: A favorable nod for Jio could spark a fresh price war in the home internet market, paving the way for ultra-affordable, multi-gigabit wireless broadband packages across urban areas.
Does this 26 GHz spectrum dispute affect the regular 5G network speeds on my phone?
No, it does not. Regular consumer mobile 5G services run on completely different frequencies, primarily using the mid-band (3.5 GHz) and low-band (700 MHz) layers. The 26 GHz band is a separate high-frequency asset currently underutilized for regular mobile lines.
What is the main difference between 3GPP and IEEE standards?
3GPP is the global corporate framework that designs traditional mobile communications like 3G, 4G, and 5G cellular networks. IEEE is an independent engineering body that develops global standards for local wireless networking, most famously the 802.11 Wi-Fi family.
Why is hardware for 3GPP Fixed Wireless Access so expensive?
FWA hardware relies on complex, proprietary radios and modem technologies controlled by a small group of international telecom vendors. Because the manufacturing scale is specialized compared to standard consumer electronics, home device costs stay significantly higher.
What is a “guard band,” and how can it resolve the Jio-Airtel dispute?
A guard band is a small, intentional slice of spectrum left completely unused between two active communication blocks. It acts as a physical buffer zone, ensuring high-power signals from one operator’s protocol do not spill over and cause interference on a competitor’s network.
Can I connect my current laptop or smartphone to Jio’s proposed 26 GHz Wi-Fi network?
No, traditional consumer devices cannot connect to 26 GHz signals directly. Jio’s plan relies on setting up a specialized outdoor receiver on your building’s roof to catch the 26 GHz beam. That receiver then translates the signal into standard Wi-Fi (like 2.4 GHz or 5 GHz) for your indoor devices.
Is the 26 GHz band used for Wi-Fi anywhere else in the world?
Using the 26 GHz band for open Wi-Fi broadband is rare globally, as most international markets have focused on opening up the 6 GHz band for unlicensed Wi-Fi 6E and Wi-Fi 7 upgrades. This makes India’s pending decision a highly watched test case for global tech observers.
How much money did the operators spend to secure these 26 GHz airwaves?
During the 2022 auctions, Jio spent roughly ₹6,990 crore to secure 22,000 MHz of spectrum in this band, while Airtel invested approximately ₹5,592 crore for a 17,600 MHz slice, and Vodafone Idea acquired a smaller portion for around ₹1,915 crore.
What are the radiation exposure risks flagged by Airtel in their counter-filing?
Airtel’s technical objection highlights that running high-power wireless broadband equipment outdoors creates radically different transmission footprints compared to standard indoor Wi-Fi routers. They argue that these radiation patterns require deep, independent testing before deployment.
What happens if the DoT rules entirely in favor of Bharti Airtel’s protest?
If the government sides with Airtel, the 26 GHz band will remain strictly locked to 3GPP mobile parameters. This would protect traditional network structures but could leave a significant portion of Jio’s mmWave spectrum assets underutilized until local device ecosystems mature.
When are the technical standard guidelines expected to be officially finalized?
The Telecommunication Engineering Centre (TEC) and the TSDSI have been working round the clock on the draft guidelines, with technical committees pushing to finalize and publish the core framework by the end of July 2026.
Conclusion
The intense standoff over the 26 GHz band highlights a fundamental dilemma facing modern telecom regulators: should spectrum policy focus on protecting existing infrastructure investments, or should it allow flexible innovation to drive down consumer costs? Jio’s proposal to run low-cost IEEE Wi-Fi protocols across its licensed frequencies is a bold challenge to traditional 3GPP cellular networks, offering an efficient path to connect millions of Indian homes to ultra-fast broadband. However, Airtel’s technical objections regarding signal interference and safety standards are grounded in valid engineering rules that cannot be ignored. As the DoT and the TEC finalize their guidelines, their decision will set a landmark precedent for India’s tech policy—determining whether the country treats its airwaves with absolute technological neutrality or keeps its high-frequency bands anchored to traditional mobile rules.
