The Cognition Diary
This episode explores how the internet works in Bangladesh in 2025. It covers the submarine cables landing in Cox's Bazar and Kuakata managed by BSCCL, the role of IIGs in routing international traffic, and how NTTNs build the nationwide fiber backbone. ISPs and mobile operators provide last-mile access via fiber (FTTH) and 4G/5G, while IXPs (BDIX) and local caches optimize domestic traffic. The system is overseen by the BTRC, facing challenges in rural reach and reliability but poised for significant capacity boosts from upcoming cables and 5G expansion.
