On top of the drivers is an application, WMCore, running as background
service. The service is started automatically at Windows startup and can be
used to change the state of the Mobile Broadband Module without end-user
interaction also prior to Windows login.
The WMCore service provides a number of functions to control the module
and retrieve information about the module and its states. The functions are
accessible through the Ericsson Mobile Broadband C++ API, see [5]. The
service is also used by Ericsson’s Wireless Manager.
