Grameenphone has completed its yearlong network swapping activities, which will develop its call and data quality and made the country's biggest mobile operator ready for better telecom services.

The operator upgraded its 7,272 base transceivers (BTSs) as part of the swapping that started on February 12, said Chief Technology Officer Tanveer Mohammad.

The network is now able to provide 3G services by upgrad-

ing some of its technical equipment and software, he said.

Mohammad spoke at a press briefing to describe the network swapping activities, at Sonargaon Hotel in the capital on Monday.

The operator also made assessments on how much internet bandwidth would be required for different parts of Dhaka for 3G services, he said.

With new network equipment, the operator is now more cost-efficient, and its operational expenditure has reduced which impacted its revenue positively, he said.

Energy consumption at the BTSs has reduced to around 50 percent, and there are 200 BTSs, which are running through solar power while 120 more are getting ready to use such power, he said.

The operator is still working to introduce more smart approach to provide more quality service, Mohammad said.

Mobile network has covered the country's 89.13 percent land and 99.16 percent population, and Grameenphone has covered 89.79 percent of the area under the network coverage, he said.
