The scientists of Vilnius Gediminas Technical Univesity (VGTU) proved that software defined radio technology can accelerate wireless internet two or even three times. This technology can also make a breakthrough in the mobile internet area: scientists forecast that in several years‘ time the mobile internet will be as fast as the fibre-optic internet, used at home.
The software defined radio technology is a kind of technology, with the help of which the communication devices adapt themselves to the environmental conditions: the device can reconfigure its parameters because of the cognitive radio, thus accelerating and strengthening the data transition flow and improving the communication connection. The cognitive radio can be compared with the artificial intelligence of the device, able to understand and learn from the environment and to react towards it.
"Let us imagine a public wireless internet point in a city, to which many internet users are connecting. The point should work flawlessly, which can be achieved, synchronizing the apparatus in an appropriate way – changing radio channel into a less noisy one, selecting corresponding output and tuning other communication parameters. The cognitive radio technology, integrated into a wireless internet communication device, will perform everything automatically", – explained Artūras Medeišis, Associated Doctor and Head of the Telecommunication Engineering Department of the Electronics Faculty at VGTU.
The cognitive radio is one of the hits nowadays among the radio communication investigators all over the world. VGTU scientists have become appreciably advanced in this area: they have already created the prototypes of cognitive radio communication devices; they have been contributing to the international research and cooperating with famous research centres and universities.
The conception and the name of the "Cognitive Radio" emerged in 1999, after the first article on this topic. The author of the article Joseph Mitola put forward the cognitive radio idea, and testing started at the laboratories. The first users of this technology were military people, whose radio communication devices were promptly adjusting to the changing combat actions, avoiding intercepts or interfering with enemy communications. Later civil wireless communication systems started using this technology.
