mobile data traffic. Future demand for more capacity can be met by allocation of more bandwidth and new spectrum bands to … mobile communication. But spectrum is a scarce resource and allocation of new licensed bands will only partly satisfy the … growing demand. Another possibility is secondary use of spectrum bands which primarily have been allocated for other services …

transition was based on a centralised model designed to release a major portion of the spectrum, whereas the Spanish model is … Spanish authorities regarding the increase in spectrum demand will make the digital transition in Spain far more expensive … release of a large amount of spectrum, in Spain, the impact of European harmonisation on national DTT planning will inevitably …

The objective of this paper is to highlight the need to consider a multitude of scenarios for the … enabled by improved spectral efficiency, adding more spectrum bands, aggregation of frequency bands and offloading to local … assuming deployment in regions in the world where both the availability of spectrum as well as the penetration of fixed phones …

There have been substantial technical and policy discussions about the spectrum needs of 5G and the necessity of … expanding access to the higher frequency spectrum, including in the millimeter wave bands from 30 to 300 GHz. The focus, however … markets continue to grow, demand may arise for spectrum in still higher frequency bands above 90GHz, including in the sub …

The essential input to the exploitation of mobile broadband known as radio spectrum is a scarce resource, whose … allocation and eventual assignment by telecommunications regulator and spectrum authorities across the world is of outmost … importance. The most popular approach to spectrum assignment is to run an auction where frequency bands get assigned over a …
