India’s 6G to Use Terahertz Bands, Enabling 1 Terabit/Second Speeds-100x Faster Than 5G
India is on the verge of a digital revolution as the government prepares to launch 6G technology, which will utilize Terahertz frequency bands to achieve blazing internet speeds of up to 1 terabit per second (Tbps), equivalent to 125 gigabytes per second. This next-generation leap, announced by Minister Pemmasani, promises to make 6G nearly 100 times faster than the current 5G networks, setting the stage for transformative advances in connectivity, industry, and everyday life.
Terahertz (THz) frequency bands refer to electromagnetic waves in the range of 0.1 to 10 THz-much higher than the millimeter waves used in 5G. These ultra-high frequencies allow for:
Massive Data Throughput: Enabling the transmission of huge amounts of data in real-time.
Ultra-Low Latency: Reducing delays to near-instantaneous levels, critical for applications like autonomous vehicles and remote surgery.
Dense Connectivity: Supporting millions of devices per square kilometer, essential for smart cities and IoT .
While 5G has already revolutionized mobile and wireless connectivity with speeds up to 10 Gbps, 6G’s projected 1 Tbps capability represents a quantum leap. Here’s how 6G will outpace 5G:
Speed: 1 terabit/second is 100 times faster than the best 5G speeds.
Capacity: 6G can handle exponentially more devices and data streams.
Reliability: Enhanced error correction and signal clarity, even in crowded environments.
New Applications: Real
Minister Pemmasani emphasized that India’s 6G roadmap is designed to position the country as a global leader in digital infrastructure. By harnessing Terahertz bands, India aims to:
Empower Smart Cities: Seamless integration of sensors, vehicles, and public services.
Boost Industry 4.0: Enabling automation, robotics, and AI in manufacturing and logistics.
Advance Healthcare: Real-time telemedicine, remote diagnostics, and even robotic surgery.
Enhance Education: Ultra-fast, immersive e-learning experiences with virtual classrooms and labs.
While commercial 6G networks are expected globally by 2030, India is fast-tracking pilot projects and research, with early trials anticipated as soon as 2027–2028. The government’s proactive policies and public-private partnerships are expected to make India one of the first countries to roll out 6G at scale.
India’s bold move to adopt Terahertz frequency bands for 6G, as outlined by Minister Pemmasani, signals a new era in digital connectivity. With speeds up to 1 terabit per second, 6G will not only redefine how Indians live, work, and communicate but will also position India as a global technology powerhouse.
