From Galwan to Siachen, Indian Army rolls out 4G, 5G network across Ladakh borders

In a landmark move, Indian Army troops posted in extreme terrains like Galwan and the Siachen Glacier now have access to 4G and 5G mobile connectivity, marking a significant leap in connecting soldiers with their families despite harsh and remote conditions.

The Army described this initiative as a "major morale booster" for personnel serving at isolated posts situated at altitudes above 18,000 feet. Officials said the network rollout covers strategic locations including Daulat Beg Oldi (DBO), Galwan, Demchok, Chumar, Batalik, Dras, and the Siachen Glacier.

Hailing it as a "transformative stride," the Army noted that the mobile connectivity will not just serve soldiers but will also empower remote border communities, helping bridge the critical digital divide across Ladakh’s challenging landscapes.

In a historic first, a 5G mobile tower has been successfully installed on the Siachen Glacier — the world’s highest battlefield — underscoring India’s technological capabilities and commitment to fortifying its frontiers through innovation.

The connectivity drive has been a collaborative effort under the Whole-of-Government approach, where the Army leveraged its robust optical fibre network and partnered with Telecom Service Providers and the Ladakh administration. The Fire and Fury Corps played a key role in coordinating and enabling mobile tower installations, with four major set-ups already operational in Ladakh and Kargil districts.

The Army emphasized that this project is not just about technology but about nation-building — digitally integrating 'First Villages' along the borders, enhancing economic activity, healthcare, education, tourism, and stemming migration by fostering new opportunities and dignity for remote populations.
