New software-defined radios allow a single radio to operate with multiple waveforms to provide a wide range of capabilities depending on frequency, waveform characteristics, and bandwidth. However, that variability also makes it difficult to establish and maintain IP connectivity. Moreover, radio-based communications can be unreliable, and if routers are unaware of each radio's condition, they cannot make effective routing decisions. Finally, network routers and radios must be able to form ad hoc networks with minimal configuration or changes. All of these challenges hinder the military's ability to have realtime access to mission-critical information.
