    摘要: A transmitter performs BLUETOOTH capability negotiation with a receiver to determine that both the transmitter and the receiver support an adaptive coding protocol, where the adaptive coding protocol enables the transmitter to send media files in different codec formats to the receiver via BLUETOOTH; determines at least one codec format that is of a media file and that is supported by the receiver; establishes an Advanced Audio Distribution Profile (A2DP) BLUETOOTH connection; determines a first codec format of a first media file; and sends the first media file to the receiver when the receiver supports the first codec format, where media data in the first media file includes a first indication, and the first indication indicates the first codec format.

    摘要: A communication system comprises an access point (203) communicating via a directional beam and a first and second wireless modem (111, 703) for establishing a first and respectively second mm wave radio communication link to the first access point (203). The first and second wireless modems (111, 703) are located on a vehicle (103) and employ electronically steerable beamforming directional antennas having a first main beams for establishing the radio communication links. A scheduler (801) schedules data of the communication over the first mm wave radio communication link and the second mm wave radio communication link in dependence on a link quality of at least one of the first mm wave radio communication link and the second mm wave radio communication link. The main beams may be formed in substantially the same direction.
