Patent ID: 8774795

Claim:
An avionics system comprising: a first main radio unit (MRU) configurable to simultaneously provide at least one safety certified channel for a cockpit of an aircraft and at least one other channel for cabin services of the aircraft with a software defined radio (SDR); a second main radio unit (MRU) configurable to simultaneously provide at least one safety certified channel for a cockpit of an aircraft and at least one other channel for cabin services of the aircraft with a software defined radio (SDR); a first RF unit configured to selectively communicate with one of the first MRU and the second MRU and send and receive signals from a first antenna, wherein the first RF unit is configured to amplify first outgoing signals from one of the first MRU and the second MRU and send the first outgoing signals to the first antenna for propagation therefrom as well as filter first incoming signals from the first antenna and send the first incoming signals to one of the first MRU and the second MRU for processing; and a second RF unit configured to selectively communicate with one of the first MRU and the second MRU and send and receive signals from a second antenna, wherein the second RF unit is configured to amplify second outgoing signals from one of the first MRU and the second MRU and send the second outgoing signals to the second antenna for propagation therefrom as well as filter second incoming signals from the second antenna and send the second incoming signals to one of the first MRU and the second MRU for processing.
