The Indian Armed Forces will use a dedicated communication network operated by state-run Bharat Sanchar Nigam Limited (BSNL) by the end of 2012
BSNL will finalise the tenders calling for the implementation of the army and the navy network by this August and implement the networks by December 2012, according to business-standard.com.
The optical-fibre network for the army and the navy costs INR80,980m ($1.7bn) while the similar project for Indian Air Force currently undergoing testing will cost INR91,750m ($2bn).
BSNL said that Indian defence would vacate the 45Mhz radio spectrum once it had built an alternative optical-fibre cable network for all the defence forces.
The Department of Telecommunications expects the defence forces to vacate the radio waves by September 2010.
The radio spectrum in the network carries voice signals in wireless devices and is essential for cellular mobile telephony to operate.
