In a landmark move to bolster digital connectivity in some of the most remote and strategically vital areas of the country, the Indian Army has successfully enabled 4G and 5G mobile networks across the high-altitude regions of Ladakh, including Eastern Ladakh, Western Ladakh, and the Siachen Glacier—the highest battlefield in the world.
The installation of multiple mobile towers now provides high-speed mobile connectivity to troops stationed at forward and critical posts such as Daulat Beg Oldie (DBO), Galwan, Demchok, Chumar, Batalik, Dras, and Siachen.

These advancements will significantly improve communication capabilities for soldiers deployed in extreme conditions, often at elevations exceeding 18,000 feet. Most importantly, it ensures that personnel serving in these isolated locations can remain in touch with their families, particularly during the severe winter months when many of these posts are cut off due to heavy snowfall and treacherous terrain.
The rollout of this project was accomplished through a Whole-of-Government approach, involving coordinated efforts by the Indian Army, Telecom Service Providers (TSPs), and the Union Territory Administration of Ladakh.
The Fire and Fury Corps, which oversees military operations in the region, played a pivotal role in implementing the project by utilising the Army's optical fibre cable (OFC) infrastructure to establish seamless mobile networks in these difficult terrains.
A key highlight of the initiative is the installation of a 5G tower on the Siachen Glacier, making it the highest 5G mobile tower in the world. In total, four mobile towers have been installed using Army logistics and infrastructure in the Ladakh and Kargil districts, further bridging the digital divide and strengthening communication networks in India's border areas.
