To cater to the growing demand, the government has decided to go forward with the plan to join a third submarine cable. This submarine cable, third of its kind, will be fully functional by 2024 and will be added around 7200 Gbps of Bandwidth to the national information infrastructure.

 Around the same time, the country's first submarine cable network is expected to be decommissioned. Built around 2005 and commissioned in 2006, SEA-ME-WE 4 is the first submarine fibre optic cable Bangladesh got connected to. Being the sole Backbone of the nation's internet connectivity, any interruption in service meant the entire nation had to suffer.

According to industry insiders, standard long route submarine fibre optic cable has a life expectancy of a 10 - 15 years. After that maintenance becomes costly and frequent. Bangladesh's first fibre submarine cable is already on its 15th year now. Human errors such as anchorage of seabound ships on the cable have resulted in some damage to the first submarine cables. When asked if the new cable will see similar downtime, Mirza Kamal Ahmed, General Manager of Bangladesh Submarine Cable Company Limited (BSCCL), said, "In the last fifteen years, we had one severe accident which was in August 2019 when an excavator damaged the second cable. Besides, the seabed in our region has frequent tremors causes disruption. Rest of the slowdown happens in National Telecommunication Transmission Network (NTTN)".

Md Emdadul Hoque, the Secretary General of Internet Service Providers Association of Bangladesh (ISPAB), however, said that the speed slows down are mostly due to unavailability of surplus connectivity. "We were sole dependent on the SEA-ME-WE 4 for a long time. Now that we have SEA-ME-WE 4, 5 and with the upcoming 6, the nationwide slowdown of the internet will reduce.". He also pointed out that transition from SEA-ME-WE 4 to 6, routine maintenance might be more frequent resulting slowdowns."

The new submarine cable is also expected to dramatically reduce the price and increase the speed of Bandwidth in Bangladesh. Over the last decade, Bangladesh already saw a steep decline in the price of bandwidth while consumption and speed saw a sharp increase. The current demand for bandwidth is around, 1600 Gbps which has just 300 Gbps just four years back in 2016. But compared to the global market, Bangladesh lags far behind. According to Ookla, the internet speed performance analysis giant, Bangladesh ranked 96th amongst 176 countries in fixed broadband.

But this is expected to change, according to Sumon Ahmed Sabir, Chief Technology Officer of Fiber@Home and Executive Council member of Asia Pacific Network Information Centre (APNIC). "When serving higher demand, the maintenance cost of submarine cables goes down resulting higher speed broadband at a lower price. Compared to the world, our consumption is low which attributes to the higher price. But the new submarine cable has a much higher capacity. So, its maintenance cost will be lower cost per Gbps which will reduce the price of bandwidth.", he said. Emdad echoed the same. He added, "We are now importing some bandwidth through international terrestrial cable from India to ensure redundancy at a higher price. If we have ample redundant capacity, speed will go up will price will go down."
