KNL has been developing its Cognitive Networked HF (CNHF) radio system since 2011, when the company was spun-off from the University of Oulu's Centre of Wireless Communication. Although it's called a radio system, CNHF is far from your in-car entertainment: it uses shortwave radio transmissions to send and receive any form of digital data, including files and real-time location data, over thousands of kilometres.
The technology behind the system combines traditional high frequency (HF) terrestrial radio technology with modern cognitive and software-defined technologies. The latter is key, as it replaces typical hardware components (such as mixers and amplifiers) with software, enabling it to work even in the most demanding environments. Meanwhile, cognitive radio can intelligently detect the wireless spectrum in its vicinity and automatically change its transmission or reception parameters according to what is the optimal wireless channel available.
