Shrivastava, however, said nothing concrete had been planned thus far on the issue of sharing and trading of airwaves, also called spectrum, since the government's norms on this subject were still awaited. "Regarding intra-circle roaming, we are in touch with five private operators -- Bharti Airtel, Reliance Jio, Vodafone India, Reliance Communications and Uninor.

While some of them approached us, we approached the others," the chairman said. "Some tests are going on with all the five companies. After this, we will have to enter into some mutual agreement with them. Within a month or two, we should be in a position to get into some kind of agreement," he added.

Intra-circle roaming pacts help companies optimise on their allotted radio frequency spectrum by sharing this scarce resource within a telecom circle -- which in the case of India is generally co-terminus with a state, as also some key cities.

For example, while travelling within a circle, the subscriber of one operator can hook on to the network of another service provider depending on whose signal is stonger in that area. This also helps in better network and infrastructure planning among the telecom operators.

Shrivastava said the main beneficiary of such pacts will be the customers.

"With intra-circle roaming agreements, since spectrum is shared, the service quality improves. In addition, it lowers infrastructure costs also. The network management is better. In the end, all this benefits the customer," he added.
