Even as state-run BSNL and MTNL look at monetising their realty assets, Union Telecom Minister Ravi Shankar Prasad on Friday said the precondition of using the land for telecom infrastructure at time of allotment may prove to be a hurdle.Speaking at the MTNL's technology centre in central Mumbai, Mr. Prasad said there are some limitations emanating from the fact that the land was allotted specifically for telecom infrastructure.He informed that a high-level committee has been formed at the departmental level to look into how to utilise the excess land holdings of MTNL and BSNL.The union minister said he would like MTNL's revenue to increase, not only in terms of improving connectivity and consumer base, but also in optimum utilisation of their resources and infrastructure. He further said the government has empowered the boards of these companies to take the right decisions. Attacking the previous UPA regime, he said MTNL, which had reported a profit of Rs 10,000 crore when the Vajpayee government demitted office, was reeling under losses of Rs 8,000 crore at the end of a decade of Congress rule.
