Abstract
Techniques for providing hybrid communications to devices on vehicles include using 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. A subsequent forward link is selected, based on the reverse data, from a plurality of forward links, each of which is supported by a different frequency band. Forward data may be multiplexed and/or multicast, and in some cases, multiple forward links may be used for distributed forward data delivery. These techniques allow for efficient data delivery to the vehicle, and in particular while the vehicle is in transit and link conditions are dynamic.
