7. Why Brazil decided to develop its own model ? 1. Non-payment of royalties ( Different from the mobile phones industry in Brazil) 2. Development of national technology ( GINGA-NCL became a ITU-T Recommendation) 3. Most appropriate system for the country's problem ( For example: a solution for the Digital Divide Problem)
