Sector watchdog the Telecom Regulatory Authority of India (TRAI) has criticised fellow regulator the Department of Telecommunications (DoT) for washing its hands of any service disruptions in the metro circles, after delays in allotting spectrum to Vodafone India and Bharti Airtel have left the duo too little time to reconfigure their networks before their current concessions expire, at the end of November. The Economic Times writes that the TRAI has urged the DoT to help the two telcos to ensure that customers are not affected, adding that there will be ‘serious degradation in telecom networks’ if the department does not help find a solution. The two providers had requested an extension of six months to their current licences to guarantee a smooth handover, but the proposal was rejected by the DoT earlier this week, on the basis that it would effectively extend the providers’ licences by around a year. In its announcement, the DoT said that any potential disruption caused by network optimisation would have to be handled by the cellcos. As previously noted by CommsUpdate, more than 35 million customers across Delhi, Mumbai and Kolkata stand to be affected by the anticipated networks issues.
