On the project

Projekt CORTIF cílí na koexistenci konkurenčních zařízení využívající stejná radiofrekveční pásma, a to jak na aplikační úrovni (stejná lokace), tak na technologické úrovni (stejná deska plošných spojů). V rámci Evropského konsorcia projektu CATRENE CORTIF výrobci mobilních zařízení a set-top boxů stanoví systémové požadavky a výrobci polovodičových součástek vyvinou nové techniky dovolující koexistenci bezdrátové komunikace. Spolu se systémovými integrátory bude pak předvedeno ověření konceptu a dosažené výsledky. Čeští účastníci projektu, společnost IMA a veřejná vysoká škola VUT, ke společnému projektu přispějí návrhem a realizací experimentálních elektronických modulů, návrhem metodiky pro měření koexistence bezdrátových mobilních systémů a integrací výsledků do bezdrátové senzorové sítě. Po celou dobu projektu bude kladen důraz na možné standardizační aktivity, spotřebu zařízení a výrobní náklady.

Description in English
There are expected to be 7 trillion wireless devices in the field by 2020. These will cover not only telecommunications but also new application areas such as e-health, traffic management and environmental monitoring. The interference problems that willemerge in such a rich environment urgently need to be addressed. It?s becoming increasingly important for the European economy. Without action a complete wireless traffic jam is expected in the nearby future. CORTIF will enable the concurrent use of RF spectrum by multiple, independent radio systems without harmful mutual interference. It is applicable across distances of different orders of magnitude; from a single PCB out to the wide area with radios that might be far apart. Key goals are: Creating the next generation of European wireless communication systems by the development of new methodologies for RF design and simulation tools. These methodologies will focus on co-existence, robustness and low cost as a prerequisite for future radio technologies. The project is targeting the whole value chain beginning from component and system design up to complete demonstration systems. When this happens it is essential that they can operate without detrimental mutual interference. Additionally, the projectwill move towards the smart environment with intelligent devices that interact with users, sense their environment, and communicate with each other, often with no human involvement.. Some of these devices are fixed, other devices are nomadic, but all must communicate and, increasingly, that communication must be wireless in order to meet their design objective. To support this brave new world, significant challenges must be overcome at multiple layers of the communication stack; from device designs toaccess protocols; spectrum management policies to standards. Communicating devices should be able to coexist without detrimental mutual interference. Meeting this objective is the purpose of CORTIF.
