Reliance Jio’s recent application to India’s Department of Telecommunications (DoT) for approval to utilize the 26 GHz spectrum band—traditionally reserved for 5G services—for WiFi deployment signals a noteworthy evolution in wireless technology strategy within the country. As one of India’s dominant telecom operators, Jio’s move displays an ambition to blend 5G and WiFi capabilities into a hybrid model that could drastically transform urban broadband experiences. This development arrives amid India’s broader digital transformation agenda and a rapidly advancing telecommunications ecosystem that demands innovation in spectrum usage and network architecture.
The telecom sector in India has been through transformative waves, notably with the commercial rollout of 5G in late 2022 by Reliance Jio and Bharti Airtel, soon joined by Vi in 2024. The spectrum auctions leading up to these launches, particularly the pivotal 2022 auction where Jio acquired significant millimeter-wave spectrum in the 26 GHz band, paved the way for these next-generation connectivity services. This high-frequency spectrum offers potential for ultra-low latency and vast bandwidth, opening doors for high-density user environments and new use cases requiring blistering data throughput.
By seeking regulatory approval to repurpose the 26 GHz band for WiFi, Jio is effectively reimagining spectrum utility, crossing traditional boundaries that separated WiFi and cellular services. Per Clause 2.3 of the 2022 spectrum auction’s Notice Inviting Applications, any change in use from 5G to other technologies mandates prior approval to prevent interference and ensure network integrity. This regulatory step not only safeguards performance but enables a pioneering hybrid infrastructure model that leverages the best of both wireless worlds.
Leveraging Millimeter-Wave Spectrum for WiFi Innovation
Standard WiFi operates mostly in lower frequency ranges such as 2.4 GHz and 5 GHz, providing broad coverage but limited speeds and capacity. In contrast, the millimeter-wave 26 GHz spectrum can deliver gigabit speeds though over shorter ranges, making it well-suited for dense urban settings where users simultaneously demand high-definition video streaming, augmented reality applications, and rapid file transfers. By piloting WiFi in this band, Jio aims to drastically upgrade the bandwidth and latency capabilities of WiFi networks in metropolitan hotspots, complementing 5G core networks without overlapping traffic loads.
This hybrid deployment promises to alleviate last-mile connectivity challenges—those tricky end-user experience gaps caused by network congestion or terrain obstacles in crowded environments. The 26 GHz WiFi could serve as a localized capacity enhancer, strategically deployed across dense urban nodes. Such integration would underpin smart city solutions, corporate campuses with private network requirements, and sprawling Internet of Things ecosystems where device density and real-time data flow are critical.
Economic and Technical Considerations
Repurposing the 26 GHz spectrum faces notable headwinds. Millimeter waves have limited propagation and are easily blocked by buildings, weather, and physical barriers, compelling operators to plan for dense concentrations of access points. This increases infrastructure complexity and costs. Jio’s experiment, therefore, represents not just a technical undertaking but an economic one—balancing deployment expenses against the promise of high-value service innovations.
The DoT’s scrutiny is paramount, as it must ensure that Jio’s hybrid approach neither degrades existing 5G performance nor disrupts the broader spectrum management ecosystem. Policymakers will likely evaluate interference risks, harmonization with national telecom strategies, and the scalability of such hybrid frameworks. Success here could inspire other operators within India—and potentially elsewhere—to adopt similar strategies, boosting competitive innovation while preserving orderly spectrum use.
Jio’s Strategic Vision Within India’s Digital Ambitions
Jio’s bid dovetails with India’s ambitious digital growth targets, where the government encourages adoption of 5G, AI, blockchain, and IoT technologies to fuel economic advancement. Through this spectrum innovation, Jio signals its intent to transcend simple service provision and become a digital infrastructure catalyst. By capitalizing on underutilized spectrum in creative ways, the company aligns with its public commitments to next-gen technological leadership, potentially unlocking new business models for B2B, content providers, and consumers.
On a global scale, this 5G-WiFi fusion trend reflects the industry’s evolving understanding that no single wireless technology can address all connectivity challenges. Integrating the ultra-low latency and massive bandwidth of 5G millimeter waves with the flexibility and ubiquity of WiFi networks offers a promising pathway to seamless, high-capacity wireless ecosystems. Jio’s initiative places India alongside other innovation hotspots adapting to the surge in wireless data demand and diversification of digital services.
In essence, Reliance Jio’s request to the DoT to deploy the 26 GHz spectrum band for WiFi shows a bold step toward maximizing millimeter-wave potential beyond conventional cellular uses. If approved, this hybrid model would not only offer superfast internet experiences and enhanced network resilience but also serve as a case study in intelligent spectrum reallocation. It encapsulates a moment where regulatory prudence meets technological ambition, creating momentum for India’s telecommunications future that could reverberate across service design, spectrum policy, and digital economy growth.
For consumers eager for uninterrupted high-quality broadband, enterprises shaping the future of smart networks, and regulators balancing innovation with order, this evolution promises to be a defining chapter. Reliance Jio’s spectrum strategy could well be the spark that ignites a new era of hybrid connectivity, laying the groundwork for India’s continued ascent as a global technology leader.
