Spectrum Usage in Mobile Broadband Communication Systems / RADIOFREKVENČU IZMANTOŠANA MOBILO PLATJOSLAS SAKARU SISTĒMĀS

The increased demand of mobile broadband consumers on services in the mobile environment with high data rate and technologically developed mobile broadband communication systems will require more spectrum to be available in the future. The new technologies as well as the existing services require frequencies for their development. The authors investigate the available and potential future mobile terrestrial frequency bands - worldwide and in Europe. An insight into the spectrum management is provided, with radio access technologies, methods for more efficient use of mobile frequency bands and frequency cross-border coordination also addressed. It is stressed that the radio frequency spectrum is a limited national resource that will become increasingly precious in the future.
