According to a report by Bangladesh Telecommunication Regulatory Commission (BTRC) disclosed on Monday, none of the mobile phone operators in the country met the 4G data speed benchmark in Chattogram Division.
However, call drop rate in all mobile operators' network was found within the benchmark except state-owned Teletalk.
BTRC made the report after a comprehensive Quality of Service (QoS) measurement through drive test in different location of Chattogram Division from 13 February to 14 March of this year.
The benchmark for 4G download speed was decided to be 7 Mbps. However, all the mobile operators had download speeds far lower than the benchmark.
The country's largest mobile operator Grameenphone's download speed was found to be 4.92 Mbps while the speed for the second largest mobile operator, Robi was found to be 3.56 Mbps. Country's third largest mobile operator Banglalink had a comparatively better speed at 6.10 Mbps.
The call drop rate in the three private operators' network in Dhaka and Chattogram was found within the benchmark.
However, state-owned Teletalk's call drop rate in Chattogram was found to be higher than the benchmark. Teletalk also has the lowest 4G download speed both in Dhaka and Chattogram among all the operators.
Sources at BTRC have said that its technical team will conduct such drive test in other divisions by next June.
