Bharat Snachar Nigam is mainly responsible for the increasing congestion between networks of cellular operators on points of interconnection, a main reason for poor call quality, regulator TRAI has said in a report.
Worst case scenarios, where congestion level on PoI is 40 per cent or more, have been experienced across the country from Patna to Patiala and Chennai to Chandigarh.
In all these places, BSNL has PoI problems with operators Bharti, Hutch, Idea, Aircel, Reliance Infocomm and Tata Teleservices, according to the Network Congestion report of TRAI for September.
The congestion at the PoI level of service providers is benchmarked at less than 0.5 per cent as per TRAI' regulation.
In a number of areas, the degree of congestion is increasing between the operators alarmingly and is far more than this benchmark.
The PoI congestion report for July-September shows that it has been increasing. In September, at 193 locations, the PoI congestion level was over 10 per cent and worst affected locations were spread across the country.
BSNL seems to have maximum PoI congestion level with Bharti and the Tatas.
In a multi-operator environment, the issue of efficient and adequate interconnection between operators is very important, TRAI said.
