The newly built third terminal of Hazrat Shahjalal International Airport in Dhaka has no mobile network coverage due to a design flaw, delaying its inauguration. The Civil Aviation Authority of Bangladesh (CAAB) discovered the issue after construction was nearly complete and has begun urgent work to install network infrastructure inside the terminal. The correction process, including opening parts of the aesthetic ceiling to lay cables, is expected to take six to seven months. According to CAAB sources, the original design did not include an in-building mobile network solution, forcing a redesign and additional costs estimated in the millions. An emergency board meeting decided to sign a five-year agreement with state-owned Teletalk to implement the network, as other operators only offered space rental without revenue sharing. The contract will be reviewed every two years, with rent increasing by 2.5 percent annually upon renewal. CAAB officials acknowledged that the absence of mobile coverage is a major operational flaw in an otherwise world-class facility. They expect the new agreement with Teletalk to resolve the issue and enable the terminal’s opening once the network installation is complete.
