The US Naval Research Laboratory (NRL) is developing the capability for radios to autonomously select and re-select frequencies to avoid bandwidth congestion and jamming.
The effort could potentially make forces less dependent on spectrum managers who must manually set channels, as well as remove the need for personnel to manually enter and re-enter those keys every time they change frequency.
Using cognitive radios (devices that can change how they transmit information), the radio should learn that a frequency is no longer good and switch to another frequency, without any interruption, and try to communicate along that channel, Andrew Robertson, communications and networks research scientist at the NRL, recently told IHS Jane's.
