Reliance Jio’s recent move to seek approval from India’s Department of Telecommunications (DoT) to utilize the 26 GHz spectrum band for Wi-Fi services signals a notable shift in the country’s telecom landscape. Traditionally earmarked for 5G mobile deployments, the potential repurposing of this millimeter-wave spectrum by a major player like Jio reveals new directions for harnessing high-frequency bands to enhance broadband connectivity. This strategic effort not only expands Jio’s digital infrastructure footprint but also ushers in a broader industry dialogue on optimal spectrum utilization, regulatory adaptation, and the future of high-speed wireless access in India.
The 26 GHz band, part of the millimeter-wave (mmWave) spectrum, offers considerable bandwidth capable of supporting ultra-high-speed wireless data transmission. Its attributes make it a prime candidate for 5G networks worldwide, thanks to the ability to transport large volumes of data at extremely low latency. Yet the band’s physical characteristics come with constraints: limited range and poor penetration through buildings or obstacles demand dense network deployments and line-of-sight alignments, complicating the rollout of widespread mobile coverage. Despite these technical hurdles, 5G mmWave remains a cornerstone for next-generation connectivity, expected to evolve into even faster 6G systems in the future.
Jio’s application to the DoT follows regulatory protocols set in the 2022 spectrum auction’s Notice Inviting Application (NIA). This framework requires telecom operators acquiring spectrum initially designated for 5G mobile use to seek clearance before converting it to other uses such as Wi-Fi. By engaging the Telecommunication Engineering Centre (TEC) for technical approval, Jio aims to ensure compliance and service quality standards. The company’s comprehensive acquisition of multiple spectrum bands in 2022, including the coveted 26 GHz, creates a fertile ground for innovation outside traditional mobile broadband models.
One of the most significant implications of shifting the 26 GHz band toward Wi-Fi lies in expanding fixed wireless access (FWA) solutions. Unlike wired broadband services, FWA leverages wireless spectrum to deliver high-speed internet directly to homes and businesses, especially beneficial in urban areas with dense populations or regions where laying fiber and cables remains prohibitively expensive. Jio’s plan could translate to delivering gigabit-level speeds over Wi-Fi, broadening user access to fast internet without the cost and logistical challenges of expanding wired infrastructure. This approach aligns well with India’s push toward digital inclusion and connectivity for underserved communities, potentially accelerating the country’s broadband penetration.
The move also signals an evolving industry trend toward flexible, hybrid management of spectrum assets. If the DoT grants Jio’s request, it is widely anticipated that other telecom giants like Bharti Airtel may seek similar approvals, leading to a more diversified utilization of high-frequency bands. This trend supports a technology-neutral regulatory stance where spectrum can be dynamically assigned across service types to maximize resource efficiency. Operators could balance between mobile broadband, fixed wireless, enterprise solutions, and other emerging use cases in a single spectrum band, optimizing returns on investment and consumer value.
Despite the opportunities, several technical and market challenges lie ahead. The inherent limitations of millimeter-wave frequencies mean massive infrastructure investment is necessary to ensure consistent coverage, requiring installation of many small cells or repeaters, particularly in obstructed urban environments. Furthermore, widespread consumer adoption hinges on the availability of compatible devices—smartphones, routers, and enterprise equipment capable of operating effectively on the 26 GHz band are still limited. Industry players and vendors will need to accelerate innovation in device ecosystems, driving down costs and improving performance to facilitate mass-market penetration.
From a policy perspective, the coexistence of Wi-Fi and mobile services within the same spectrum band demands careful balancing. The 26 GHz band remains vital for long-term 5G evolution and beyond, and any repurposing must preserve mobile network integrity while enabling alternate uses. Jio’s proposal might prompt regulators to revisit spectrum licensing frameworks, advocating more flexible and dynamic models that accommodate rapid technological and market changes. Such regulatory agility could position India at the forefront of digital connectivity innovation, fostering new business models and service expansions.
Strategically, this initiative reflects Jio’s ambition to strengthen its leadership in India’s digital infrastructure ecosystem. By pioneering multi-use applications of high-frequency spectrum, Jio can enhance broadband speeds, expand coverage, and enrich user experiences across both consumer and enterprise sectors. The potential for integrating ultra-high-speed Wi-Fi with mobile broadband services can support burgeoning data demand propelled by video streaming, cloud computing, and immersive technologies like augmented and virtual reality.
In summary, Reliance Jio’s request to the DoT to enable Wi-Fi services on the 26 GHz band is a forward-looking move that could redefine spectrum usage in India. Utilizing this 5G-spectrum asset for Wi-Fi could unlock new, versatile broadband solutions, bridging gaps in coverage and speed across challenging environments. While technical constraints and regulatory complexities remain, this step highlights the dynamic interplay between innovation, policy, and market needs driving the nation’s wireless connectivity evolution. The outcome of this approval process stands to influence how India’s telecom sector adapts to rapidly shifting consumer expectations and technological horizons in the years ahead.
