Abstract: A communication system for automatically choosing a communication modality from a plurality of communication modalities for use for communication between distant communication entities is provided. The communication system includes a controller configured to: receive a message in the form of one of a first plurality of modalities from a message originator for transmission to a message recipient and select at least one modality for sending the message to the message recipient. To select the controller is configured to: determine the existence of any predetermined vehicle context requirements, predetermined static requirements, predetermined communication service provider requirements, communication context requirements, message recipient preferences, and message originator preferences; and make the selection based on those requirements and preferences. The controller is further configured to convert the received message to the selected modality and cause the message to be transmitted to the message recipient.

Abstract: A radio system comprises a plurality of software defined radio units, and a plurality of digital data switches each in operative communication with at least one of the radio units, with the digital data switches operatively connected to each other. A plurality of antenna units are each in operative communication with at least one of the radio units through at least one of the digital data switches. A plurality of radio resources managers are each operatively coupled to one or more of the digital data switches, with each of the radio resources managers configured to control one or more of the digital data switches to route digital data between the radio units and the antenna units.

Abstract: The radio system comprises a radio unit and an antenna unit coupled to the radio unit. The antenna unit is physically separate and located remote from the radio unit. The antenna unit further comprises a digital pre-distortion engine configured to pre-distort a modulated digital data signal; a digital to analog converter configured to convert the pre-distorted digital data signal to a pre-distorted analog data signal; and a power amplifier configured to amplify the pre-distorted analog data signal which distorts the pre-distorted analog data signal. The distortion introduced by the power amplifier is opposite to the pre-distortion introduced by the digital pre-distortion engine such that the pre-distortion introduced by the digital pre-distortion engine approximately cancels the distortion introduced by the power amplifier.
