As I mentioned earlier. At this time India does not use Satellite communication at the 'dispersion' level.How do soldiers get networked information on the battlefield? Either satellite or terrestrial data links, the terrestrial requires repeaters on the ground so is only possible if you control the lines behind you. The satellite can reach anywhere.
You seem to be unplugged from history of technology and are pigeon-holed into the latest tech! AM communication won't need repeaters for hundreds/thousands of kms (what was used in WWI & WWII) - that's the way HAM radios work! FM communication will need repeater in about 50 kms. India does have that level of vast mobile terrestial comm equipment.
