Meaning of Cognitive Networked Radio

The Cognitive Networked HF Radio (CNHF) senses its operating environment without the intervention of the user and can adapt to the user’s communications needs. A CNHF Radio can intelligently detect whether any portion of the spectrum is in use and can temporarily use it without interfering with the transmissions of other users.

The KNL network is capable of operating independently from other networks and infrastructure. Thus with built-in cellular and LAN network, advanced configurations can be established. Our CNHF solutions receive the whole HF spectrum at once and have extremely fast link establishment (less than 500ms).
