3 telecom operators namely Aircel, Vodafone and PSU BSNL were reported as failing to meet quality of services benchmark set by DOT with regards to call drops as Economic times reported today. The performance on call drop is accessed through quality of service (QoS) parameters like call drop rate/circuit switch voice drop rate for which benchmark is less than or equal to 2 per cent. For worst affected cells having over 3 per cent traffic channel drop during cell bouncing busy hour or any other hour of a day, the benchmark is less than or equal to 3 per cent.
"As regards, the parameter worst affected cells having more than 3 per cent call drop rate, Aircel is not meeting the benchmark in 18 service areas, BSNL in 5 and Vodafone in 2 service areas," Telecom Minister Ravi Shankar Prasad said in a written reply to the Rajya Sabha.
As per the performance monitoring report for 2G services for the quarter ending December 2014, the benchmark for parameter call drop rate is not met by Aircel in 2 service areas and BSNL in 3 service areas and for 3G services, Aircel is not meeting the benchmark for parameter worst affected cells having more than 3 per cent call drop rate in 12 service areas and BSNL in 3 service areas.
Operators need to invest more in active and passive infrastructure to ensure that they can provide seamless services and are able to meet the QoS bench mark. This involves setting up more telecom towers and having sufficient amount of spectrum to avoid congestion at towers.
