Abstract
Techniques for providing hybrid communications to devices on vehicles include using a selected modulation scheme on a forward link to deliver data (that is intended to be received by an on-board device) onto a vehicle, and using a reverse link in a different frequency band to send reverse data from the vehicle. Based on the reverse data, a subsequent pre-defined modulation scheme for a subsequent forward transmission is selected from a plurality of modulation schemes corresponding to a plurality of performance levels of data delivery. The selections may be based on a current geo-spatial location of the vehicle, a type of data, and/or on one or more other dynamic conditions. The forward data may be multiplexed and/or multicast. Thus, adaptive modulation is achieved in a hybrid communications system in which the forward link and the reverse link to the vehicle are supported by different wireless communication bands.
