3. History of Telecom systems in Bangladesh
The liberalization of Bangladesh’s telecommunications sector began with small steps in 1989 with the issuance of a license to a private operator for the provision of inter alia cellular mobile services to compete with the previous monopoly provider of telecommunications services the Bangladesh Telegraph and Telephone Board (BTTB). Significant changes in the number of fixed and mobile services deployed in Bangladesh occurred in the late 1990s and the numbers of services in operation have subsequently grown exponentially in the past five years. The incentives both from government and public sectors have helped to grow this sector. It is now one of the biggest sector of Bangladesh. As a populous country, it's huge market has attracted many foreign investors to invest in this sector
