The following chart summarizes the OIDs used to get or set the general operational characteristics of wireless WAN miniports and/or their NICs.
Currently, there are no defined statistics OIDs for the wireless WAN medium.
The following describes each of the preceding OIDs and their respective associated structures more fully.
References for the set of network-type-dependent OID_WW_XXX follow those for the OID_WW_GEN_XXX.
Wireless Operational Characteristics
Unless otherwise specified, the requesting protocol must allocate all buffer space necessary to complete OID requests. Underlying NDIS drivers need only copy the data into the supplied buffers.
To account for differences in hardware architectures and structure packing, structure members must be aligned on an 8-byte (NDIS-defined type NDIS_PHYSICAL_ADDRESS) boundary and the sizeof operator in "C" (or an analogous function) must be used to calculate the lengths of structure elements.
Some network devices support external interfaces to configure the device. Therefore, it is possible for some objects to change dynamically, which is outside the control of the underlying miniport.
Many of these OIDs have associated structures with members of type NDIS_VAR_DATA_DESC, defined as follows:
typedef struct _NDIS_VAR_DATA_DESC {
USHORT Length; // number of bytes of data in buffer
USHORT MaximumLength; // total size of buffer in bytes
LONG Offset; // offset in bytes, relative to struct
} NDIS_VAR_DATA_DESC, *PNDIS_VAR_DATA_DESC;
This structure defines a type used to describe buffer space relative to the base virtual address of the NDIS_VAR_DATA_DESC structure itself. In other words, a pointer to a buffer is not explicitly provided by this type; only the offset within the buffer space is provided. Because this descriptor does not use an actual pointer, a user-mode application can allocate a buffer together with its descriptor of this type and provide an offset within this buffer relative to the base virtual address of the descriptor. This allows structures containing these descriptors to be passed between user mode and kernel mode without address mapping. An Offset outside the range sizeof(NDIS_VAR_DATA_DESC)) is invalid.
Queries that return information of type NDIS_VAR_DATA_DESC should zero terminate buffers (that is, set the Offset member of this structure to NULL) and return zero as the buffer size if the requested information is unavailable. For example, if the revision number of the software/firmware in the device is unknown, a wireless WAN miniport should return zero for the Length and NULL for the Offset at SWVersionNum for an OID_WW_GEN_DEVICE_INFO query.
The definition of each OID_WW_GEN_XXX that follows describes the data type at InformationBuffer in the NDIS_REQUEST structure passed in to the MiniportQueryInformation or MiniportSetInformation function.
OID_WW_GEN_NETWORK_TYPES_SUPPORTED
For this OID, a miniport returns an array of types supported by the driver and its NIC that has any proper subset of the following system-defined values:
NdisWWMobitex
NdisWWPinpoint
NdisWWCDPD
NdisWWArdis
NdisWWDataTAC
NdisWWMetricom
NdisWWGSM
NdisWWCDMA
NdisWWTDMA
NdisWWAMPS
NdisWWInmarsat
NdisWWpACT
NdisWWGeneric
Any miniport that cannot claim full compliance with any particular type from the preceding list should return NdisWWGeneric for this query. Otherwise, the miniport should return a list of the particular type(s) for which it can provide fully compliant support.
Sets and indications are irrelevant for this OID.
OID_WW_GEN_NETWORK_TYPE_IN_USE
As a query, this OID requests MiniportQueryInformation to return the current NDIS_WW_NETWORK_TYPE used by the NIC driver. See OID_WW_GEN_NETWORK_TYPES_SUPPORTED for possible values.
As a set, this OID requests that MiniportSetInformation set the NIC and itself to use the specified NDIS_WW_NETWORK_TYPE value. If a miniport supports only a single type of network, it sets this type as the network default so a bound protocol is unlikely to make this OID request of such a miniport.
NdisWWGeneric should be specified in set requests to underlying drivers that do not claim full compliance with any of the enumerated network types in response to a query.
If the underlying miniport can support more than one type of network, a bound protocol should make this OID request to set the network type immediately following its successful call to NdisOpenAdapter and prior to calling NdisRequest with OID_WW_GEN_HEADER_FORMAT_IN_USE. Such a protocol should query the current operating network type prior to setting it. If the device is operating in the correct mode, then no further action is required other than registering for the OID_WW_GEN_INDICATION_REQUEST on return from the OID_WW_GEN_NETWORK_TYPE_IN_USE request.
When a miniport has completed a set operation requested by this OID, the network type has been set for all bound protocols.
If any bound protocol has enabled indications with OID_WW_GEN_INDICATION_REQUEST, the miniport must call NdisMIndicateStatus to notify such protocol(s) if the network type changes. It can ignore the TriggerValue member that was specified in the OID_WW_GEN_INDICATION_REQUEST.
OID_WW_GEN_HEADER_FORMATS_SUPPORTED
For this OID, a miniport returns an array of header formats the NIC driver can support as one or more of the following system-defined values:
NdisWWDIXEthernetFrames
NdisWWMPAKFrames
NdisWWRDLAPFrames
NdisWWMDC4800Frames
DIX Ethernet is the default header format. Every wireless WAN miniport driver must support this format. Any miniport can support additional formats. However, a miniport is likely to support at most one other format that is native to its NIC.
Sets and indications are irrelevant for this OID.
OID_WW_GEN_HEADER_FORMAT_IN_USE
As a query, this OID requests MiniportQueryInformation to return the current NDIS_WW_HEADER_FORMAT it is using. See OID_WW_GEN_HEADER_FORMATS_SUPPORTED for possible values.
As a set, this OID requests MiniportSetInformation to use a particular header format that it returned in response to a preceding OID_WW_GEN_HEADER_FORMATS_SUPPORTED request. If no bound protocol requests a set, the miniport uses DIX-Ethernet framing by default.
If the underlying miniport can support more than one type of header, a bound protocol should make this OID request immediately following its successful call to NdisRequest with OID_WW_GEN_NETWORK_TYPE_IN_USE. A successful set request changes the header format in use for all bound protocols.
If any bound protocol has enabled indications with OID_WW_GEN_INDICATION_REQUEST, the miniport must call NdisMIndicateStatus to notify such protocol(s) if the header format changes. It can ignore the TriggerValue member that was specified in the OID_WW_GEN_INDICATION_REQUEST.
This OID requests MiniportSetInformation to place the specified indication request on the driver's event queue.
This OID allows bound protocols to register themselves to be notified of changes associated with particular wireless OIDs. Such a protocol passes an NDIS_WW_INDICATION_REQUEST structure to NdisRequest that specifies an OID_WW_GEN_XXX code and, for some OID codes, a trigger value. On return from such an OID_WW_GEN_INDICATION_REQUEST, the current value of the specified OID code will be in the InitialValue member, unless otherwise stated in the definition for the OID_WW_GEN_XXX specified in the Oid member.
The NDIS_WW_INDICATION_REQUEST structure is defined as follows:
typedef struct _NDIS_WW_INDICATION_REQUEST {
NDIS_OID Oid; // IN
UINT uIndicationFlag // IN
UINT uApplicationToken // IN OUT
HANDLE hIndicationHandle; // IN OUT
INT iPollingInterval; // IN OUT
NDIS_VAR_DATA_DESC InitialValue; // IN OUT
NDIS_VAR_DATA_DESC OIDIndicationValue // OUT
// only valid
// after indication
NDIS_VAR_DATA_DESC TriggerValue // IN
} NDIS_WW_INDICATION_REQUEST
The members of this structure contain the following information:
Oid
The OID_WW_GEN_XXX code for which the miniport should indicate events.
uIndicationFlag
Specifies a bitmask in which one of the following flags can be set:
OID_INDICATION_REQUEST_ENABLE
The miniport should call NdisMIndicateStatus if the event specified in this structure occurs.
OID_INDICATION_REQUEST_CANCEL
The miniport should cancel notifications for the specified event. The values supplied in the Oid and hIndicationHandle members must match the values specified in a preceding OID_WW_GEN_INDICATION_REQUEST.
All other bits in uIndicationFlag are reserved for future use.
uApplicationToken
Specifies an application-defined (or protocol-defined) token that is returned by the miniport when it posts the specified event.
hIndicationHandle
Specifies a miniport-determined handle. The application will save this handle and possibly use it to cancel this request subsequently (see uIndicationFlag).
iPollingInterval
Specifies an interval, in milliseconds, at which the miniport should poll the wireless NIC to monitor the value of the given OID.
If this member is set to -1, the miniport should use its own default settings to poll the device. Before returning, the miniport must set this member to the polling interval, in milliseconds, it will use for this indication. This allows the application to determine if the driver is sampling the OID too often, to possibly cancel its original request, and to make another request that the driver poll the NIC at a more appropriate interval.
InitialValue
On input, points to an NDIS_VAR_DATA_DESC-type buffer that can contain information necessary to initialize the requested notification, for instance, as in the case of OID_WW_GEN_CURRENT_ADDRESS. The miniport sets information about the current value of the specified OID in this buffer before returning or completing this request, whichever occurs first.
OIDIndicationValue
On input, specifies NULL. Before the miniport makes the event notification, it allocates an NDIS_VAR_DATA_DESC-type buffer to contain the value of the specified OID, and fills in its copy of the NDIS_WW_INDICATION_REQUEST structure.
A protocol can reference the miniport-allocated buffer only during the status indication of the event. The allocating driver can deallocate this buffer and release all resources necessary to trigger the event on return from its call to NdisMIndicateStatus with this event.
TriggerValue
On input, specifies the virtual address of an NDIS_VAR_DATA_DESC-type buffer containing a value the underlying driver uses to decide when to indicate the specified event, or this member can be NULL, depending on the given Oid value. The miniport can ignore this member for OID codes that trigger on a change in status. See the descriptions of individual OID_WW_GEN_XXX for specifics.
The miniport must fill in the InitialValue and iPollingInterval members of the given structure with the state of the driver's current information. When the given OID has reached the trigger value, the miniport fills in the OIDIndicationValue member of this structure. The initiator of this request cannot access anything in the NDIS_WW_INDICATION_REQUEST structure it allocated until ownership is returned to the protocol, either when this request is returned to its ProtocolRequestComplete function or because the returned status from NdisRequest is something other than NDIS_STATUS_PENDING.
After event notifications for a particular OID have been enabled by this request, a wireless WAN miniport should fill in the appropriate information and call NdisMIndicateStatus with NDIS_STATUS_WW_INDICATION to notify NDIS, which forwards such a notification to interested protocols, according to the following guidelines:
·For OID_WW_GEN_XXX codes that use the TriggerValue:
·While InitialValue < TriggerValue, the miniport continues to monitor for the specified condition. It posts such an event when the present value for the OID becomes >= the given TriggerValue.
·If InitialValue = TriggerValue, the miniport fills in remaining information in the given structure and calls NdisMIndicateStatus to post the event immediately.
·If InitialValue > TriggerValue, the miniport should post the event when the present value for the OID becomes <= TriggerValue.
·For OID_WW_GEN_XXX codes that do not use the TriggerValue:
The miniport should post the event when a status change occurs, as described for that OID_WW_GEN_XXX.
After a requested event is posted, the calling application must submit another indication request to receive another NDIS_STATUS_WW_INDICATION event. Due to the asynchronous nature of calls to NdisRequest, a protocol writer should be aware that the requested event could be posted prior to the return of a call to NdisRequest with OID_WW_GEN_INDICATION_REQUEST. The uApplicationToken member can be used to facilitate demultiplexing of each such event.
Any attempt to cancel an OID_WW_GEN_INDICATION_REQUEST that has already occurred can be ignored by the underlying driver.
Many OID_WW_GEN_INDICATION_REQUESTs can be outstanding for a particular OID. Making several calls to NdisRequest with this OID can establish several trigger points. When one of several OID_WW_GEN_INDICATION_REQUESTs causes an event notification, only that trigger is canceled, but all other OID_WW_GEN_INDICATION_REQUESTs remain enabled.
NDIS delivers a miniport's event indications to every protocol that is bound to that underlying driver serially. Consequently, NIC drivers must copy the contents of the indication request. A NIC driver must fill in the hIndicationHandle value prior to scheduling the request on its internal event queue and returning from the call to MiniportSetInformation. This ensures that bound protocol(s) can detect their own respective event notifications when they occur. Consequently, a miniport should set a value in hIndicationHandle that is unique each time it processes this request, such as a monotonically increasing 32-bit value (transaction ID), to ensure that collisions do not occur. The value for this member can be reset to zero every time the miniport initializes.
When a miniport indicates an event for this OID, it must pass a pointer to its copy of the indication request as the Status parameter when it calls NdisMIndicateStatus. Bound protocol drivers that receive the indication must copy the indicated information into their own internal buffer space, assuming any particular protocol determines that the hIndicationHandle value indicates an event of interest to that protocol.
As a general rule, every protocol should check the hIndicationHandle value when an event notification is made and return control as soon as each protocol's ProtocolStatus function determines the indicated event is not of interest. Otherwise, the effect of notifying all bound protocols of miniport-indicated events is a degradation in performance for the miniport and for all bound protocols.
Event data is guaranteed to be valid only until a ProtocolStatus function returns control. On return from NdisMIndicateStatus, the indicating miniport can release all context for the specified event.
Queries and indications are irrelevant for this OID.
This OID requests the miniport to return initialization-time information about itself and its NIC.
This request uses a WW_DEVICE_INFO structure, defined as follows:

In either case, this request uses one of the following values:
| Value | Meaning |
| 0 | Transmitter enabled |
| 1 | Transmitter disabled |
| -1 | Transmitter state unknown |
A typical use of this OID would be to temporarily disable the NIC's transmitter before entering a construction blasting zone. MiniportSetInformation should return NDIS_STATUS_INVALID_DATA if the value at InformationBuffer for this request is -1.
If any bound protocol has enabled indications with OID_WW_GEN_INDICATION_REQUEST, the miniport must call NdisMIndicateStatus to notify such protocol(s) if the NIC's transmitter state changes. It can ignore the TriggerValue member that was specified in the OID_WW_GEN_INDICATION_REQUEST.

The format of the current address depends on the header format, which must be one of the supported header formats listed with OID_WW_GEN_HEADER_FORMATS_SUPPORTED.
This request uses a WW_CURRENT_ADDRESS structure, defined as follows:
typedef struct _WW_CURRENT_ADDRESS {
NDIS_WW_HEADER_FORMAT Format;

| 1 | Driver suspended |
When a miniport suspends itself, it should release any hardware resources, such as the serial port, it uses in its operational state. This operation can be initiated in the control panel when an end user wants to reassign the hardware resource for other uses, such as sending AT commands to a serial device on the same serial port that the NDIS driver was using.
If any bound protocol has enabled indications with OID_WW_GEN_INDICATION_REQUEST, the miniport must call NdisMIndicateStatus to notify such protocol(s) if the driver's suspension state changes. It can ignore the TriggerValue member that was specified in the OID_WW_GEN_INDICATION_REQUEST.

If any bound protocol has enabled indications with OID_WW_GEN_INDICATION_REQUEST, the miniport must call NdisMIndicateStatus to notify such protocol(s) if the encryption state changes. It can ignore the TriggerValue member that was specified in the OID_WW_GEN_INDICATION_REQUEST.
This OID requests the miniport to return information about the quality of the link between its NIC and the network as follows:
| Value(s) | Meaning |
| 0 | The wireless NIC is not in contact with the network. |
| 1-100 | The driver can communicate with the base station at the given quality for the link, expressed as a normalized value. 100 designates the highest possible quality for the link. If a NIC indicates only whether it is in or out of network contact, its driver should return zero for out of contact and 100 for in contact. |
| -1 | Channel quality is unknown. |
Any bound protocol that simply monitors the in/out state of network contact by an underlying wireless WAN NIC should either call NdisRequest with OID_GEN_MEDIA_CONNECT_STATUS or wait for an NDIS_STATUS_MEDIA_[DIS]CONNECT indication by the miniport.
If any bound protocol has enabled indications with OID_WW_GEN_INDICATION_REQUEST, the miniport must call NdisMIndicateStatus to notify such protocol(s) according to the TriggerValue that was specified in the OID_WW_GEN_INDICATION_REQUEST.

| -1 | Registration status is unknown. |
If any bound protocol has enabled indications with OID_WW_GEN_INDICATION_REQUEST, the miniport must call NdisMIndicateStatus to notify such protocol(s) if the registration state changes. It can ignore the TriggerValue member that was specified in the OID_WW_GEN_INDICATION_REQUEST.

| Value | Meaning |
| 0-100 | The charge of the battery as a percentage, where 100 means it is fully charged. |

As a set, this OID requests the miniport latch a single AT command to be executed. Such a command always begins with the prefix "AT" or "at."
This request is generic for executing AT commands through NDIS driver(s). See the Metricom modem reference manual for information about the AT commands and S registers specific to this device. The data described by this structure is always a NUL-terminated ASCII string.
This request uses a WW_MET_FUNCTION structure, defined as equivalent to the NDIS_VAR_DATA_DESC structure, which was defined previously.
