The European Commission has presented a strategy for more flexible use of the radio spectrum for electronic communication services. The radio spectrum consists of all waves operating at frequencies between 3 kHz and 300 GHz. It is divided into 'bands' used, for example, by terrestrial television (between 400 and 800 MHz) and mobile phones (900, 1800 and 2000 MHz). To avoid interference, public authorities regulate the characteristics of radio emitters and licensed spectrum users. The digital revolution, however, brought about the 3G standard wireless access technologies and digital broadcasting, making traditional radio spectrum regulation inefficient. The Commission will now coordinate the work of EU Member State authorities to remove access and usage restrictions for this band and will include the issue in its review of the current EU telecom rules.
