Call drop, poor internet connection worry users

News Report Even as mobile phone users continue to complain about regular call drops and poor internet services, the Bangladesh Telecommunication Regulatory Commission(BTRC)is yet to take anyinitiative to address the growing menaces. Some users say they face call drop problem five to six times a day and that they often have to wait for a long time to get through. Users are also complaining about getting 2G or 3G in places where they are supposed to get 4G internet services. Shamsunnahar, a resident of Bashundhara residential area, uses both Grameenphone and Robi SIMs. She said poor mobile network has made speaking on phone an irritating experience. “The calls are dropped several times even when the network is available,” she said. Another resident of the area, Sarwar Alam, who also uses Robi and GP SIMs, said his experience was similar to that of Shamsunnahar. Rahman, a resident of Malibagh who uses Grameenphone, said he faced call dropissue five to six times a day. Between November 6 and 8 of last year, the BTRC conducted a Quality of Service (QoS) test in 15 areas of the capital. It made 3,300 machine generated calls with a duration of 90 seconds. Similar tests were conducted in other cities. Test reports showed GP, the country’s largest mobile operator, recorded a call drop rate of 3.38 percent. Second largest operator Robi’s call drop rate was 1.35 percent while Banglalink’s rate was 0.58 percent and state-owned Teletalk’s rate was 1.58 percent. But the BTRC and International Telecommunication Union set 3 percent as the limit. Grameenphone took an average of 10.14 seconds for connecting to the dialed number. The time was 6.15 seconds for Robi, 7.69 seconds for Banglalink and 7.11 seconds for Teletalk. In this case, the BTRC set 7 seconds as the benchmark for connecting with the dialed number. 4G internet speed was also tested. According to the Bangladesh Telecommunication Regulatory Commission (BTRC), a 2 percent call drop is acceptable while the International Telecommunication Union’s tolerable level was 3 percent. For India, the acceptable call drop was 2 percent while for Malaysia it was 5 percent, said mobile operators at a working session at the La Vinci hotel in Dhaka. There is no such ceiling for countries like the United Kingdom, France, Germany and Australia. The authority set 7 Mbps as the lowest speed for 4G carriers. But speed provided by the top three operators was below the lowest limit set by the BTRC. The average downlink speed of GP was 5.88 Mbps while 5.91 Mbps was recorded for Robi and 5.18 Mbps for Banglalink. Teletalk was not operating as a 4G carrier during the test. “We’ve received lots of complaints about dropped calls. Even ministers are facing the problem,” Posts and Telecommunications Minister Mustafa Jabbar said when asked about the situation. He said the BTRC has been directed to take action against those concerned. Jabbar said the mobile network operators in the country do not have enough spectrums to handle huge subscribers. “The number of dropped calls is high among GP users as it (the company) handles comparatively more subscribers. But there’s no scope to compromise the quality of service,” he added. Asked about GP’s call drop issues, BTRC Chairman Jahurul Haque noted that all the operators had some problems. “We take action to solve issues whenever subscribers lodge complaints,” he said. We won’t compromise in case of quality.” Haque said a notice seeking explanation about dropped calls was issued to the operators concerned, adding that the situation has improved a little recently. “The Quality of Service Regulation has already been issued to verify the quality of operators. Besides, test drives are being conducted in various places including Dhaka. The quality of service varies from operator to operator. We’re working to improve the quality of all operators in the country,” the BTRC chief said. Asked about the steps taken, Haque said various problems impeding quality service are being solved through discussion with the authorities concerned. He provided detailed information of the complaints lodged by the subscribers. In March, the BTRC received 334 complaints against GP, 448 against Robi, 149 againstBanglalink, 166 against Airtel and 101 against Teletalk. Brig Gen (retd) SM Farhad, secretary general of the Association of Mobile Telecom Operators of Bangladesh, said the operators always try to reduce the number of dropped calls. He noted that natural hazards such as storm, downpour and power-cut can cause problems at mobile towers. Asked why the operators do not purchase spectrum, he said they are expensive compared to other countries. “Operators are interested in purchasing spectrum. But they don’t proceed due to the high price. They’ll buy if the price is reduced.” According to the BTRC, there were 160.59 million mobile phone subscribers in the country until April this year.GP has 74.473 million subscribers, Robi 47.574 million, Banglalink 34.547 million and Teletalk 3.995 million. Besides, there are 93.702 million internet subscribers in the country. Of them, 87.910 million use Mobile Internet while 0.060 million use WiMax and 5.732 million use ISP+PSTN. In the session “Quality of Service: Expectation and Reality” organised by the Association of Mobile Telecom Operators of Bangladesh (AMTOB), operators said fibre optic cable cut, spectrum shortage, shortage of spots for establishing telecommunications sites and densely populated city areas were the main causes for the call drops. “In the city, there are dozens of restricted areas where we cannot set up our networks and frequent use of jammers also causes call drops,” said Shahed Alam, executive vice-president and head of regulatory affairs at Robi, the second largest operator. The Defense Officers Housing Schemes in the capital do not allow setting up of mobile networks inside their areas alongside the authorities of Bashundhara residential area, Banasree, officers club and Ramna area, he said. Mobile operators also cannot set up networks from Banani to Airport for some unresolved issues and from Bijoy Sarani to Jahangir Gate there are huge jammers similar to those at the old central jail, said top executives of a number of operators. Some mosques also use jammers, they said. “The same happens in the Chittagong port, DOHS and airport areas,” said Alam. Cell phone jammer is an electronic device that blocks transmission of signals between a mobile phone and a base station. By using the same frequency as a mobile handset, it creates strong interference for communication between the caller and receiver. Operators said when a call is generated by a customer it passes through a number of channels such as nationwide transmission networks, internet connections, internet exchanges and in some cases international gateways, before reaching a receiver. The operators have nothing to do if something goes wrong at any channel, the top executives said. (Inputs taken from UNB)
