OID_WWAN_DEVICE_CAPS
OID_WWAN_DEVICE_CAPS returns the capabilities of the MB device, including the cellular technology it supports, the classes of packet data it supports, the radio frequencies it supports, the type of voice service it provides, and whether it uses a Subscriber Identity Module (SIM card). The supported cellular technology and whether the device uses a SIM are particularly important because network provider selection and SIM user interfaces depend on the values of these two capabilities. The manufacturer and firmware revision are returned as optional fields.
Set requests are not supported.
Miniport drivers must process query requests asynchronously, initially returning NDIS_STATUS_INDICATION_REQUIRED to the original request, and later sending a NDIS_STATUS_WWAN_DEVICE_CAPS status notification containing a NDIS_WWAN_DEVICE_CAPS structure that indicates the capabilities of the MB device when completing query requests.
Remarks
Starting with Windows 8, the MB driver model has been updated to version 2.0. Windows 8 miniport drivers should set the Header.Revision member of the NDIS_WWAN_DEVICE_CAPS structure to NDIS_WWAN_DEVICE_CAPS_REVISION_2 for query requests. Windows 7 miniport drivers should set the Header.Revision member of the NDIS_WWAN_DEVICE_CAPS structure to NDIS_WWAN_DEVICE_CAPS_REVISION_1 for query requests.
For more information about using this OID, see WWAN Driver Initialization Procedure.
Miniport drivers can access device memory when processing query operations, but should not access the provider network or the Subscriber Identity Module (SIM card).
Many "world-wide" MB devices today support multiple frequency bands because the frequency bands for 2.5G/3G vary from country to country. The list of all the radio frequencies specified in the 3GPP standards (for GSM-based networks) and 3GPP2 standards (for CDMA-based networks) is shown in the following tables. Both standards adopt a similar band classification scheme.
