As the number and variety of smartphones and other connected devices keeps growing, the need for radio spectrum grows with it. Cognitive radio technology developed under the EU-funded QOSMOS project could help meet these needs while controlling telecom costs, improving service and driving the development of new markets.

In the near future, the telecom industry will be faced with three challenges: a need for more radio spectrum, an ever-increasing demand for data, and consumers' increasing unwillingness to pay for it. Spectrum, however, is a finite resource.

The QOSMOS project addressed the twin problems of scarcity and cost by developing cognitive radio technology that dynamically optimises the use of radio spectrum, by accessing under-utilised portions of the spectrum and sharing spectrum across devices.

'The idea is to break down silos,' says Michael Fitch of British Telecom, who coordinated the QOSMOS project. 'Every new service and technology needs a new spectrum, and silos are formed when there are umpteen different devices that use umpteen different parts of the spectrum.'

This diversity does not make for efficient spectrum management. The project partners therefore developed three technologies: a central manager that controls the spectrum 'portfolio' in real-time for a region or country; a resource manager that allocates the spectrum to individual systems and senses the environment; and a cognitive radio terminal.

The project also developed a prototype transceiver to generate FBMC (Filter Bank Multicarrier transmission) waveforms. FBMC is expected to replace the OFDM (Orthogonal Frequency Division Multiplexing) technology that is more commonly in use today. With FBMC transmission, spectrum is carved out in rectangular blocks so that it is tightly packed for more efficient spectrum use.

    We already tried dead cats. Please work to change the laws so we can do our exhaustive test using live cats.

    Sorry, but it won't work unless the cats are both dead and alive at the same time.
