The scale is massive. BSNL placed orders for one lakh indigenously developed 4G sites for pan-India deployment. As of 28 February 2026, the government reported that 97,906 4G sites had been installed and 96,103 sites were on-air. This is a full national rollout, covering urban pockets, rural belts, border regions, hilly terrain and locations where commercial viability has always been difficult for private operators.

Hydrogen trains fit into this larger ecosystem as a specialised solution for routes where full overhead electrification involves terrain, heritage, environmental or economic complexity.

Under the leadership of Raipur Municipal Corporation, and with the participation of technical experts, builders, institutions and citizens, the city launched a large-scale rainwater harvesting and groundwater recharge drive.

SkyCast is important because aviation safety depends heavily on what happens in the lower atmosphere around an airport. Aircraft descent, final approach, landing and take-off are all sensitive to visibility, wind shear, turbulence, moisture, fog density and vertical atmospheric changes. Delhi’s airport faces some of the most difficult winter fog conditions in the country, where dense fog, pollution particles and low visibility can delay flights, divert aircraft and disrupt passenger movement. SkyCast brings these atmospheric details into one integrated monitoring framework.
