2. Background: Abstract המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory 2  g20 cellular engine supports various operations (sms, data transmission, voice, etc.)  Each operation requires an Input using AT commands  During the integration process, customers need to spend time for accessing and using the cellular engine interfaces

3. Abstract המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory 3 Project Goals:  Develop a software API Layer which allows users to control the g20 cellular engine through these APIs  The software API will be used as customer reference code  Develop an easy to use GUI application for executing the most common g20 functionalities

4. System architecture המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory 6 The Software is implemented in layers:  Driver Layer – Handling the Serial Port I/O  Wrapper Layer for the Serial I/O – interface from the Driver Layer To C language  AT Commands interpreter Layer – Executes commands using the Wrapper layer  API Modules layer – Each module (SMS, voice, etc.) will include all functionalities required  GUI/Shell Layer – an optional layer, for activating the APIs directly during development stage
