The Vision of 5G Technology
Imagine downloading a full HD movie in mere seconds or experiencing lag-free virtual reality from the comfort of your living room. This is the potential of 5G — the fifth generation of wireless technology. With speeds up to 10 Gbps, latency as low as one millisecond, and the capacity to connect up to a million devices per square kilometer, 5G is not just an upgrade; it’s a revolution. It has the power to redefine industries, transform daily life, and fuel the growth of smart cities, autonomous vehicles, and advanced healthcare systems.
Globally, 5G is expected to generate $1.3 trillion in revenue by 2030, with India estimated to contribute $150 billion to this figure. Yet, these lofty promises come with caveats, especially in the Indian context.
Why 5G Hasn’t Reached Its Potential Yet
Despite the global fanfare, 5G remains a distant reality for many in India. While metro cities have begun pilot rollouts, majority of the countrymen are still struggling with consistent 4G. What’s holding us back?
1. High Infrastructure Costs
Building the infrastructure for 5G is neither simple nor cheap. For instance, laying fiber optic cables — the backbone of 5G — costs between ₹50,000 and ₹1 lakh per kilometer. India currently has only about 38% fiberization of its telecom towers, compared to over 80% in countries like the US and China. This glaring gap hampers the deployment of high-speed networks. Fiberization of telecom towers is the process of connecting radio towers with optical fiber cables. It’s a critical component for the successful deployment of 5G networks and is often called the “master key” for a faster 5G rollout.
Fiberization offers many benefits, including:
- High bandwidth: Fiber-optic cables provide high bandwidth and low latency.
- Large data transmission: Fiberization enables the transmission of large amounts of data for 5G services.
- Stronger backhaul support: Fiberization provides stronger backhaul support, which is the part of the network that connects the core and the edge.
- Insulation from interference: Fiber-optic cables offer high insulation from interference.

2. Spectrum Allocation Issues
India’s spectrum auctions have historically been expensive due to various policy and legal issues. In 2021, spectrum prices in India were 7-8 times higher than those in markets like South Korea. High costs discourage telecom operators, already reeling under financial stress, from acquiring sufficient bandwidth to ensure robust coverage.
3. Device Affordability
Only 8% of smartphones in India were 5G-enabled by the end of 2022, and these devices often cost upwards of ₹15,000. With India’s per capita income hovering around ₹1.5 lakh, such devices remain out of reach for the average citizen. Now the 5G enabled devices are increasing but still it is far from enough.
4. Rural-Urban Divide
Roughly 65% of India’s population resides in rural areas, yet these regions account for only about 30% of the country’s mobile internet usage. While urban areas might witness faster 5G rollouts, rural India faces challenges in even accessing basic 4G services, let alone high-speed 5G.
5. Dependence on Foreign Technology
India imports over 80% of its telecom equipment, making it reliant on global vendors like Ericsson, Huawei, and Nokia. This dependence not only inflates costs but also raises security concerns, particularly in a geopolitically sensitive environment. China is dominating the telecom equipment market, which poses security and political compulsions to opt for much expensive equipment from other nations.
Challenges Being Faced by 5G Technology
Beyond India’s borders, global challenges add another layer of complexity:
1. Spectrum Scarcity and Allocation
The ideal spectrum bands for 5G, particularly the mid-band (3.5 GHz), are often scarce. Governments globally must balance allocation for telecom needs with other essential services like defense and broadcasting.
2. Energy Consumption
5G networks, while efficient in data transmission, demand a dense network of small cells and antennas. A study by GSMA estimates that 5G networks could consume up to 2.5 times more power than 4G, presenting environmental and financial challenges.
3. Cybersecurity Risks
The enhanced connectivity of 5G comes with heightened security risks. In 2020 alone, India reported over 1.15 million cybersecurity incidents, a number poised to rise with 5G-enabled IoT devices becoming commonplace.
4. Integration with Legacy Systems
Shifting from 4G to 5G isn’t seamless. Telecom operators must manage the high costs of upgrading existing infrastructure while ensuring backward compatibility for older devices and networks.
Resolving the Present Issues
The hurdles are significant, but not insurmountable. India’s journey toward 5G adoption involves coordinated efforts across multiple fronts:
1. Policy Reforms
The Indian government has taken steps to reduce spectrum prices and simplify licensing norms. For instance, the 2022 spectrum auction saw base prices reduced by 39% compared to previous auctions, making participation more attractive for telecom operators.
2. Indigenous Development
Under the Atmanirbhar Bharat initiative, companies like Tejas Networks and C-DOT are developing indigenous 5G equipment. This not only reduces costs but also ensures greater control over network security.
3. Public-Private Partnerships
Projects like BharatNet, aimed at connecting rural areas with high-speed internet, exemplify the role of public-private collaboration. As of December 2022, over 5 lakh kilometers of optical fiber had been laid under this initiative.
4. Affordable Devices
Domestic manufacturers are working on sub-₹10,000 5G smartphones, expected to drive mass adoption. By 2025, it is projected that 40% of smartphones in India will be 5G-capable.
5. Green Technology
Telecom operators are investing in energy-efficient hardware and exploring renewable energy sources to power 5G towers, reducing the carbon footprint of the network.
Transformative Potential of 5G in India
1. Healthcare
India faces a doctor-patient ratio of 1:1400, far below the WHO-recommended 1:1000. 5G-enabled telemedicine can bridge this gap, especially in rural areas, by providing real-time consultations and even facilitating remote surgeries using robotics.
2. Education
Over 240 million children in India lack access to digital education. With 5G’s high-speed connectivity, immersive virtual classrooms and interactive learning platforms can become accessible even in remote villages.
3. Agriculture
India loses over ₹2 lakh crore annually due to inefficient agricultural practices. 5G-powered IoT devices can optimize irrigation, monitor soil health, and provide real-time weather updates, significantly boosting productivity.
4. Industry and Manufacturing
The introduction of 5G can facilitate Industry 4.0 practices, including predictive maintenance and automated supply chains. According to McKinsey, smart factories could increase India’s manufacturing GDP by $35 billion by 2030.
5. Smart Cities and Governance
India’s urban population is expected to reach 600 million by 2030. 5G can support the development of smart cities, with intelligent traffic systems, efficient waste management, and enhanced public safety through connected surveillance systems.
Disruption in Technology and Business
1. Startups and Innovation
India, already home to over 80,000 startups, can see a surge in innovations leveraging 5G in areas like fintech, healthtech, and logistics. This ecosystem could generate over 1 million new jobs by 2025.
2. Telecommunications
5G will push telecom operators to diversify their revenue streams, moving beyond traditional voice and data services to offer integrated solutions for industries.
3. Retail and E-commerce
With 5G, hyper-personalized shopping experiences powered by AI and IoT can become mainstream, enhancing customer satisfaction and boosting sales.
4. Global Competitiveness
By adopting 5G, India can position itself as a global technology leader, attracting foreign investments and driving exports in telecom equipment and solutions.
Conclusion
5G technology represents a transformative opportunity for India, but realizing its full potential requires overcoming significant challenges. By addressing infrastructural gaps, ensuring affordability, and fostering indigenous innovation, India can leverage 5G to bridge the digital divide and drive economic growth. The next decade will determine whether India emerges as a global leader in this digital revolution or remains a follower in the race for technological supremacy.
