In a bid to keep pace with the ever-evolving global market, the government has recently mandated the Centre for Development of Telematics (C-DOT) to initiate research and development for 6G and other futuristic technologies. The next generation telecom technology, 6G, is projected to be commercially launched between 2028-2030. With speeds estimated to be approximately 50 times faster than its predecessor, 5G, 6G technology has the potential to revolutionize communication.
Understanding the Basics of 6G Technology
The sixth-generation wireless, or 6G, is set to succeed the current 5G cellular technology. Promising higher capacity and significantly reduced latency, it aims to operate on higher frequencies than 5G networks. One of the primary objectives of 6G internet is to support one microsecond-latency communication, which is about 1,000 times faster than one millisecond throughput. It proposes the utilization of the currently unexploited terahertz band of frequency. While terahertz waves, which fall between infrared waves and microwaves on the electromagnetic spectrum, are tiny and fragile, their utilization can open up a vast amount of free spectrum, leading to astonishing data rates.
Potential Benefits of 6G Technology
The advent of 6G technology is expected to bring about considerable advancements in various sectors. These include imaging improvements, enhanced presence technology, and better location awareness. Furthermore, its higher frequencies would allow much faster sampling rates, greater throughput, and higher data rates.
The integration of sub-mm waves and frequency selectivity could usher in significant advances in wireless sensing technology. With regards to digital capabilities, 6G technology could simplify devices, making them easier to use, wear, and carry, thereby benefiting paramedics, educators, and agro-technicians who often work in remote areas.
In the context of India, this technology could optimize public transportation by improving the utilization of the country’s rail, air, and road networks. Additionally, artificial intelligence and massively parallel computing architectures could help address transportation and scheduling challenges.
Challenges and Roadblocks
While the future of 6G technology seems promising, there are several challenges that need to be addressed. These include ensuring energy efficiency, preventing signal loss due to obstructions and atmospheric water droplets, and maintaining robust cybersecurity and data protection measures.
Adopting new models for antenna design, miniaturization, edge cloud, and distributed AI will be crucial, along with ensuring end-to-end security and privacy. Meanwhile, the availability of semiconducting materials that can utilize multi-THz frequencies is yet another hurdle.
Furthermore, THz waves can be obstructed by water vapor present in the atmosphere. This necessitates the development of complex mathematical models to ensure data reaches its destination efficiently.
C-DOT: Pioneer in Telecommunications Development
C-DOT, established in 1984, is an autonomous telecom research and development centre operating under the Department of Telecom, Ministry of Communications. As a registered society and a publicly funded research institution, C-DOT is currently engaged in realizing various flagship programmes of the Government of India, including Digital India, BharatNet, and Smart Cities.
Planning Ahead: The Way Forward
To progress towards 6G, the government needs to articulate a long-term vision coupled with a solid multi-year plan, substantial investments, and minimal bureaucracy. Moreover, effective execution of the new electronics manufacturing policy, as outlined in the India Trillion Dollar Digital Opportunity document (2019), is necessary.
India must aim to cultivate not just leadership for major tech firms like Google and Microsoft, but also promote homegrown innovation based on the principles of ‘Talent, Technology, and Trust’. It is crucial to replicate the success of space and nuclear technologies missions to achieve technological self-reliance or Atmanirbharta. By 2047, India’s centenary of Independence, exhibiting leadership in 6G could indeed be a fitting tribute to the nation’s progress.
