Mobile broadband is increasing rapidly both when it comes to traffic and number of subscriptions. The swift growth of the demand will require substantial capacity expansions. Operators are challenged by the fact that revenues from mobile broadband are limited, just a few per cent of APRU, and...

Radio spectrum is a vital asset and resource for mobile network operators. With spectrum in the 800 and 900 MHz bands coverage can be provided with fewer base station sites compared to higher frequency bands like 2.1 and 2.6 GHz. With more spectrum, i.e. wider bandwidth, operators can offer...

The introduction of mobile broadband technology, smartphones and dongles has resulted in a tremendous increase of 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...

The regulatory landscape is changing towards more flexible spectrum management schemes. Such schemes are expected to make additional spectrum resources available and lower the spectrum access barriers. Emerging spectrum authorization schemes such as secondary access (TV White Space) and Licensed...
