  • the communication may be for different purposes, for example, the transmission of voice data to allow a vehicle occupant to conduct a voice call with someone remote from the vehicle, or the transmission of data, such as media data, to and from an entertainment or information device formed either as an integral part of the vehicle systems or a separate mobile device connected to the vehicle systems. Additionally, it may also be desirable to be able to communicate data concerning the status of the vehicle's operating systems to a remote location, for example a service centre.
  • the preferred communication channel is a wireless communication channel, which may for example be a cellular telephone system or a satellite communications system.
  • a wireless communication channel Whilst an individual vehicle may be equipped and configured to use a number of different communication channels, for example may be equipped with both cellular and satellite communication systems, each communication channel is typically operated separately. Consequently, there will be instances where communication over one of the available communication channels is either unavailable or of a very poor quality due to known issues, such as a lack of cellular communication network in the vehicle's particular location, or the unavailability of satellite communications due to the vehicle being out of line of sight of a communications satellite. In such circumstances the particular data communication requiring the unavailable or degraded communication channel cannot occur or can only be accomplished at an undesirably low quality.
  • apparatus for wireless communication from a vehicle comprising a first transceiver configured to establish a first communication channel via a first wireless communication system and transmit a first signal to a communication server, and a second transceiver configured to establish a second communication channel via a second wireless communication system and transmit a second signal to the communication server, wherein the first and second transceivers are configured to transmit respective first and second signals simultaneously.

  • An advantage of the vehicle communication system having at least a first and second transceiver for utilising separate wireless communication systems is that data transmission can occur over both communication channels simultaneously so as to improve the likelihood of at least one of the channels achieving successful communication. Equally, this arrangement permits different data types, e.g. voice data and vehicle status data to be separately transmitted at the same time.

  • At least one of the first and second transceivers may be arranged to receive a third signal from the communications server. This permits at least one of the communication channels to be used for bidirectional communication.
  • the vehicle communication system may further comprise a communication server having a first receiver configured to receive the first signal and a second receiver configured to receive the second signal, and having a processor configured to compare the first and second signals.
  • the communication server is thus enabled to take further actions based on analysis of both the received first and second signals.
