Abstract
Techniques for optimizing modem use for data delivery to vehicles that are near to or parked at ports include using a high-capacity forward communications link, in a first frequency band, to support a logical forward link of a data tunnel via which data is delivered between a data provider and the vehicle. Instead of using the reverse communications link of the first frequency band, though, a reverse communications link in a different frequency band is used to support the reverse logical link of the data tunnel, as reverse data typically requires less bandwidth. Thus, the forward communications link is used in a high-throughput, unidirectional manner. Forward data may be multiplexed and/or multicast, and in some cases, multiple forward communications links may be used in parallel to support the logical forward link of the data tunnel.
