OID_WW_GEN_CHANNEL_QUALITY
This OID requests the miniport driver to return information about the quality of the link between its NIC and the network as follows:
| Value | 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 NdisRequestwith OID_GEN_MEDIA_CONNECT_STATUSor wait for an NDIS_STATUS_MEDIA_[DIS]CONNECT indication by the miniport driver.
If any bound protocol has enabled indications with OID_WW_GEN_INDICATION_REQUEST, the miniport driver must call NdisMIndicateStatusto notify such protocol(s) according to the TriggerValue that was specified in the OID_WW_GEN_INDICATION_REQUEST.
Sets are irrelevant for this OID.
