The government on Saturday said state-run MTNL is sharing its passive infrastructure such as mobile towers with Reliance Communications, Bharti airtel, Vodafone and Idea for generating revenue.

However, MTNL has not shared any Base Transceiver Station (BTS) till date, Minister of State for Communications and IT Milind Deora informed the Rajya Sabha in a written reply.

MTNL is sharing 15 sites with Reliance Communications, two with Bharti airtel, five with Vodafone, eight with Idea Cellular and one with Aircel, he said.

Replying to another question, Deora said that though MTNL is, in general, meeting the Quality of Services (QoS) benchmarks prescribed by the telecom regulator Trai regarding mobile services, some complaints of subscribers are received.

These complaints, as and when received, are attended promptly by the company. To further improve the QoS, measures like BTS addition, capacity augmentation and upgradation, antenna tilting, optimisation of network and drive test are undertaken on a continuous basis by MTNL, he said.
