The trend towards wireless communication at events continues
EURO 2008 also pushed the frequency-technical boundaries. It was only possible to assign sufficient frequencies at the last minute thanks to flexible frequency assignment, a specially designed database and smooth-running procedures. The trend towards handling all communication at events using predominantly wireless technology was also confirmed by the very high demand for frequencies at major concerts, festivals etc.
Side-effects of the digital dividend
The splitting-off of the 790 – 862 MHz frequency range for mobile radio has led to uncertainty among affected manufacturers and users of wireless microphone systems. This widespread application demands an unoccupied radio spectrum. Our advice, the search for possible alternative bands and lobbying work in international bodies have been greatly valued.
Some neighbouring countries have a substantially greater need for broadcasting frequencies than Switzerland. This situation will be aggravated by the reduction in the frequency range in favour of mobile radio. Within the framework of bilateral and multilateral negotiations, we are attempting to ensure frequency utilisation which is as dense and free from interference as possible.
Assignment rules for radio relay systems updated
Back to overview Frequency management
After just two years of preparation, the assignment rules for radio relay systems have been adapted to the state of the art, with a view to making use of the resource in a sustainable and interference-free manner. In the future, for example, the application of automatic transmitter power control (ATPC) will become standard. Microwave links are sensitive to rain: comprehensive quality tests have shown that Switzerland has to be sub-divided into two precipitation zones in order to take into account the different attenuation induced by rain. The use of (adaptive) modulation techniques is already becoming apparent – an indication that the body of rules will also 'live on' in the future.
