The Department of Telecommunications (DoT) has accepted the Telecom Regulatory Authority of India's (TRAI) proposal to allow service providers to share active infrastructure. The move will enable telecom operators to lower tariffs and reduce their expenditure by over 50 per cent. DoT has also accepted TRAI's proposal of not mandating infrastructure sharing. The mode of commercial agreement has been left to service providers. DoT is, however, of the opinion that levies charged on various operators sharing passive infrastructure should not be more than 1.2 times the amount being charged from a single player.
