NEW DELHI & CHENNAI — In an aggressive bid to transition India from a consumer of telecom technologies to a primary creator of global telecommunications intellectual property, the Department of Telecommunications (DoT) has authorized experimental spectrum allocations across the sub-terahertz range (95 GHz to 300 GHz). Coordinated by the Bharat 6G Alliance, the regulatory directive paves the way for commercial hardware prototyping in ultra-dense wireless communications, holographic telepresence, and ubiquitous satellite-terrestrial convergence.
While India’s 5G rollout achieved the fastest geographical deployment recorded globally, policymakers and engineering consortiums are executing a multi-year blueprint to ensure Indian patents form the foundational core of the International Telecommunication Union’s (ITU) 6G standardizations.
Terahertz Spectrum and 100 Gbps Wireless Throughput
At the national 6G testbed established across IIT Madras, IIT Delhi, and the Society for Applied Microwave Electronics Engineering & Research (SAMEER), research teams demonstrated a sustained wireless transmission speed of 100 Gigabits per second across a 1.2-kilometer terrestrial path using 140 GHz radio frequencies.
The transition to terahertz bands unlocks unprecedented bandwidth density, enabling instantaneous data transfers required by autonomous vehicular networks, interactive artificial intelligence models, and industrial digital twins that cannot tolerate microsecond latency spikes.

Satellite Direct-to-Device (D2D) Integration
A transformative architectural shift in the Bharat 6G standard is native non-terrestrial network (NTN) integration. Unlike traditional mobile networks that depend entirely on ground-based cellular towers, 6G incorporates satellite Direct-to-Device (D2D) capabilities directly into commercial chipsets.
Standard smartphones will seamlessly switch between terrestrial 6G micro-cells in urban corridors and low-Earth orbit (LEO) satellite constellations over rural hinterlands, maritime economic zones, and Himalayan borders, permanently eradicating mobile coverage blackouts across the subcontinent.
Indigenous Patent Monetization and Manufacturing
India’s telecommunications R&D expenditure has begun yielding measurable strategic returns. Indian researchers and private hardware firms have registered over 380 Standard Essential Patents (SEPs) with international bodies. This domestic patent portfolio ensures that as global carriers deploy 6G infrastructure toward the turn of the decade, Indian technology firms will collect cross-licensing royalties rather than paying external licensing fees.
