How to Create a Mobile Phone

  • Article

The Mobile Phone configuration provides a starting point for mobile devices using wireless data communications. To create a platform configuration for a Microsoft Windows CE-based mobile handset, you can use the New Platform Wizard, or you can build a custom platform by manually selecting the necessary components.

Because the Mobile Phone configuration targets a specific form factor, you can use the Emulator included with Platform Builder to view and test your new image. For more information, see Mobile Handheld Configuration.

Hardware and Software Assumptions

  • Your Platform Builder installation includes the Emulator: X86 board support package (BSP). For more information, see Creating an Emulator-Compatible Platform.
  • Your test hardware includes a serial port-based phone device. To test the complete functionality your Mobile Phone configuration provides, you must include a test device capable of testing functionality such as wireless telephony, and voice and data communications. For more information, see Writing to a Serial Port.

To track your progress in the following table, select the check box next to each step.
