Techniques are directed to using communication metric data associated with multiple modulation schemes to achieve a link quality metric that is representative of the link as a whole, across the multiple modulation schemes that may be employed on the link. A calculation of a link quality metric may be triggered by a network layer transmission attempt, with communication metrics accumulated at the link layer of the link. A filter used to calculate the link quality metric may be updated based on network layer transmission attempts, based on successful and/or unsuccessful transmissions at a Media Access Control (MAC) layer of the link. More generally, a calculation of link quality may be triggered by a higher layer transmission attempt while being calculated based on transmission attempts at a lower layer of the link.

Techniques are directed to opportunistically communicating using a modulation scheme that is other than the preferred modulation scheme, to update communication metric data for the second modulation scheme, such as a modulation scheme that has not been used as much as the first modulation scheme. The second modulation scheme may be associated with a higher data rate than the preferred modulation scheme. If communication using the second modulation scheme is successful, subsequent communication may be carried out exclusively using the second modulation scheme, and the communication metrics may develop such that the second modulation scheme becomes the preferred modulation scheme.
