1. A reconfigurable radio communications system, comprising:

  • a digital data bus;

    a control bus;

    a first reconfigurable radio communication unit responsive to the digital data bus and the control bus, the first reconfigurable radio communication unit including a first and a second multifunction radio transceiver responsive to at least a first antenna, the first reconfigurable radio communication unit further comprising;

    a first power supply voltage converter configured to derive voltages from a first normal power supply and a first emergency power supply; and

    a second power supply voltage converter configured to derive voltages from the first normal power supply and the first emergency power supply, the first emergency power supply remaining operable when the first normal power supply fails;

    a second reconfigurable radio communication unit responsive to the digital data bus and the control bus, the second reconfigurable radio communication unit including a first and a second multifunction radio transceiver responsive to at least a second antenna, the second reconfigurable radio communication unit further comprising;

    a third power supply voltage converter configured to derive voltages from a second normal power supply and a second emergency power supply; and

    a fourth power supply voltage converter configured to derive voltages from the second normal power supply and the second emergency power supply,the second emergency power supply remaining operable when the second normal power supply fails;

    wherein each of the first and the second multifunction radio transceivers of the first and the second reconfigurable radio communication units are operable to simultaneously transmit and receive data on at least two separate channels from different frequency bands; and

    wherein one of the multifunction radio transceivers is automatically reconfigurable to maintain radio communication functions previously performed by a faulted multifunction radio transceiver.
