File Compression Alternatives for Windows Mobile Devices

Windows Mobile 6.5

Windows Mobile devices that use Global System for Mobile Communications (GSM) support WAP Binary XML (WBXML) compression for over-the-air (OTA) push provisioning messages.

WBXML tokenization is a standard way to compress XML text files to a tokenized format for OTA transmission efficiency. For information about the WBXML token tables used by OTA push provisioning messages, and for information about Microsoft custom parameter token tables, see WBXML and Windows Mobile Devices.

If the XML provisioning file is provided in a .cab or .cpf file, you can use MSZIP to compress the provisioning file, which typically results in compression gains of greater than 50 percent. The Windows Mobile devices CAB Installer automatically decompresses the .cpf file and extracts the .cab file contents.
