The Bangladesh Telecommunication and Regulatory Commission is working to introduce a technical survey to ensure quality of telecom services to improve customer satisfaction. Under the initiative, the regulator has purchased equipment to examine the operators' service response time, call drops, signal-to-noise ratio, cross-talk, echo, interrupts, frequency response and loudness levels. The regulator also recently asked the operators to submit their coverage status on all the highways, railways and riverine areas within the month, to ensure uninterrupted service. Sunil Kanti Bose, chairman of BTRC, said the service quality of the operators is falling as of late, and they will have to explain the reasons, The Daily Star reported online. The regulator also wanted to know why users are facing more call drops now, he said. None of the mobile operators is ensuring the quality of their service and call drop has become a regular phenomenon, according to the minutes of a commission meeting last month. The regulator is still in a consultation with the operators to prepare the criteria on which their service quality will be measured, said an official of a mobile operator.
