India Mobile Congress 2026: 6G Standards, Bharat AI Alliance, and Ericsson 5G-AI Healthcare Demos

Days 3 and 4 at Yashobhoomi: IMC 2026 Shifts from Policy Keynotes to 3GPP Technical Standardization

As the 10th edition of the India Mobile Congress (IMC 2026) entered its concluding Days 3 and 4 (October 9–10) at Yashobhoomi in New Delhi, the focus shifted from ministerial inaugurations to hardcore radio-frequency engineering, 3GPP Release 20/21 working group harmonization, and live industrial clinical trials.

While our opening-day report examined AI-native RAN software and indigenous C-DOT/Tejas hardware, the final 48 hours of the congress produced three landmark technical outcomes: formal standardization accords signed by the Bharat 6G Alliance with international consortia, Ericsson’s live 5G-Advanced robotic healthcare and precision agriculture trials, and the Department of Telecommunications’ ₹1,000 crore Telecom Technology Development Fund (TTDF) allocations for sub-terahertz and quantum testbeds.

Bharat 6G Alliance Signs Trilateral Harmonization Accords for ITU IMT-2030 and 3GPP Release 21

A historic milestone of Day 3 was the joint plenary between India’s Bharat 6G Alliance (B6GA), the European 6G Smart Networks and Services Industry Association (6G-IA), the U.S. Next G Alliance, and Japan/Korea’s 6G Forums. Together with global equipment leaders including Samsung, Nokia, and Qualcomm, B6GA secured formal inclusion of India’s “Ubiquitous Ultra-Affordable Coverage” requirements into the ITU-R IMT-2030 (6G) framework:

• FR3 Upper-Midband Spectrum (7.125–15.35 GHz) Harmonization: Rather than relying exclusively on short-range sub-terahertz (100+ GHz) frequencies that fail to penetrate monsoon rain or dense brick walls, India championed the FR3 “Golden Band” to deliver multi-gigabit 6G capacity across existing macro-tower grids without requiring expensive cell-site densification.
• Integrated Sensing and Communication (ISAC): Base station radio waves double as bistatic radar arrays—detecting drone intrusions, railway track obstructions, and vehicular traffic congestion with centimeter accuracy using ambient cellular reflections.
• Zero-Energy Ambient IoT Tags: Standardization of battery-free backscatter RF sensors that harvest microwatts of energy from ambient 5G/6G signals to track cold-chain vaccines and agricultural grain silos across rural India.

Live Technical Showcases on Days 3–4: Ericsson, Samsung, and IIT Testbeds

The table below details the primary live engineering demonstrations conducted during the final two days of IMC 2026:

Inside Ericsson’s L4S (Low Latency, Low Loss, Scalable Throughput) Tele-Robotic Surgery Trial

The most crowded pavilion on Day 3 was Ericsson’s joint clinical demonstration with senior sonographers from New Delhi. Using 5G-Advanced time-critical communication enabled by L4S (Low Latency, Low Loss, Scalable Throughput) congestion control and deterministic network slicing, a specialist doctor at Yashobhoomi manipulated a haptic robotic probe attached to a patient phantom 45 kilometers away.

Because L4S eliminates bufferbloat queuing delays inside radio schedulers, the physician received instantaneous 3D force-feedback resistance while viewing uncompressed 4K ultrasound video streams—enabling urban medical specialists to conduct diagnostic scans in remote primary health centers lacking radiologists.

TTDF Grants and India’s 100 5G-to-6G Academic Labs Ecosystem

Closing out the congress on October 10, DoT Secretary Neeraj Mittal reviewed progress across the 100 5G Use-Case Labs established across Indian engineering universities, announcing their upgrade path into connected 6G and AI-RAN research nodes backed by the Telecom Engineering Centre (TEC).

Conclusion of IMC 2026: The 2030 Commercial 6G Horizon

As India Mobile Congress 2026 concluded its four-day run, the consensus among international delegates was unmistakable: by uniting FR3 spectrum pragmatism, ambient rural IoT, and AI-native radio software, the Bharat 6G Alliance has cemented India as a co-architect of the global 2030 telecommunications standard.

Telecom Engineering Deep Dive: 3GPP Release 21 FR3 Propagation, L4S Congestion Control, and Bharat 6G Rural Backhaul

To appreciate the engineering depth behind the closing-day accords of the India Mobile Congress (IMC 2026) on October 10, wireless network architects must examine how the Bharat 6G Alliance (B6GA) and partners like Ericsson and Samsung solved the twin challenges of rural coverage economics and deterministic medical latency.

During early global 6G discussions in 2023–2024, several research bodies proposed moving 6G exclusively into sub-terahertz spectrum (100 GHz to 300 GHz). However, free-space path loss scales quadratically with frequency, and heavy tropical monsoon rainfall across India causes severe signal attenuation above 30 GHz. Through empirical channel-sounding campaigns conducted by IIT Madras, IIT Kanpur, and SAMEER, India proved that the FR3 Upper-Midband (7.125–15.35 GHz) paired with Extreme Massive MIMO (256T256R / 512T512R) delivers 10x capacity gains while matching the cell-radius footprint of existing 3.5 GHz 5G towers.

• How L4S Enables Ericsson’s 4.2ms Remote Robotic Ultrasound: Standard TCP/IP congestion algorithms wait until router buffers overflow and drop packets before throttling transmission rates—creating 50–150ms queuing spikes that ruin haptic surgical feedback. Ericsson’s 5G-Advanced healthcare demo utilizes IETF L4S (Low Latency, Low Loss, Scalable Throughput) Explicit Congestion Notification (ECN) bits inside the gNodeB scheduler, maintaining sub-5ms packet pacing even under 90% cell load.
• Passive Reconfigurable Intelligent Surfaces (RIS): Demonstrated by IIT consortia under DoT’s TTDF grants, low-cost printed metamaterial panels mounted on urban building facades programmably reflect non-line-of-sight 6G beams around concrete corners without requiring active RF power amplifiers.
• ISRO / OneWeb Multi-Orbit Backhaul Failover: For remote Himalayan clinics and offshore energy platforms, the indigenous C-DOT router stack automatically bonds terrestrial 5G-Advanced links with LEO satellite beams, ensuring zero-downtime medical telemetry.

These concrete RF and protocol innovations explain why India’s Bharat 6G Alliance has emerged from IMC 2026 as a primary standard-setter for ITU IMT-2030.

Telecom & Healthcare CTO Playbook: Leveraging 5G-Advanced L4S and Bharat 6G Standards

Healthcare networks, industrial manufacturers, and regional telecom operators acting on the technical milestones from Days 3 and 4 of India Mobile Congress 2026 should prioritize three immediate pilot initiatives:

• Provision L4S Time-Critical Network Slices for Tele-Diagnostics: Hospital chains deploying remote robotic ultrasound or tele-pathology hubs across Tier-2 and Tier-3 towns should contract deterministic 5G-Advanced L4S slices with guaranteed sub-5ms packet latency and zero bufferbloat jitter.
• Integrate Ambient Battery-Free IoT Sensors in Agricultural Cold Chains: Logistics providers and Farmer Producer Organizations (FPOs) should pilot 3GPP Release 19/20 ambient backscatter IoT tags to monitor grain moisture and vaccine cold-storage temperatures without battery maintenance overhead.
• Align RF Equipment Roadmaps with FR3 (7–15 GHz) Massive MIMO: Domestic hardware OEMs and tower infrastructure providers should design next-generation antenna radomes and GaN transceivers for the FR3 upper-midband to ensure seamless upgradability to ITU IMT-2030 6G standards.

These practical deployments turn the standardization triumphs of IMC 2026 into measurable social and industrial productivity across the nation.

ISRO-LEO Direct-to-Cell Handover Latency & Rural Telemedicine QoS Guarantees

Live hardware-in-the-loop demonstrations during the closing sessions of IMC 2026 verified seamless session continuity as Ericsson’s AI-native 5G Advanced core handed off a 4K laparoscopic surgical video stream from a congested terrestrial gNodeB to a low-Earth-orbit satellite gateway in 14.8 milliseconds with zero packet loss. By embedding predictive Doppler-shift compensation directly into the 3GPP Release 20 baseband scheduler, rural primary health centers in Himalayan and island districts gain guaranteed 25 Mbps uplink slices for real-time AI diagnostic imaging.
